The definite integral by using the properties of even functions, we can evaluate the definite integral ∫(1²/246 + 7) cot(dt) over the interval [-2, I].

We can rewrite the integral as ∫(1²/246 + 7) cot(dt) = ∫(1/246 + 7) cot(dt). Since cot(dt) is an odd function, we can split the integral into two parts: one over the positive interval [0, I] and the other over the negative interval [-I, 0]. However, since the function we are integrating, (1/246 + 7), is an even function, the integrals over both intervals will be equal.

Let's focus on the integral over the positive interval [0, I]. Using the properties of cotangent, we know that cot(dt) = 1/tan(dt). Therefore, the integral becomes ∫(1/246 + 7) (1/tan(dt)) over [0, I]. By applying the integral property ∫(1/tan(x)) dx =[tex]ln|sec(x)| + C[/tex], where C is the constant of integration, we can find the antiderivative of (1/246 + 7) (1/tan(dt)).

Once we have the antiderivative, we evaluate it at the upper limit of integration, I, and subtract its value at the lower limit of integration, 0. Since the integral over the negative interval will have the same value, we can simply multiply the result by 2 to account for both intervals.

The given interval [-2, I] should be specified with a specific value for I in order to obtain a numerical answer.

To find the scalar product of vectors AB and AC, we calculate the dot product between them. To find the angle between the vectors AB and AC, we use the dot product formula and the magnitudes of the vectors.

To find the scalar product of vectors AB and AC, we need to calculate the dot product between the two vectors. The scalar product, denoted as AB · AC, is given by the sum of the products of their corresponding components. So, AB · AC = (xB - xA)(xC - xA) + (yB - yA)(yC - yA) + (zB - zA)(zC - zA). To find the angle between the vectors AB and AC, we can use the dot product formula and the magnitude (length) of the vectors. The angle, denoted as θ, can be calculated using the formula cos(θ) = (AB · AC) / (|AB| |AC|), where |AB| and |AC| represent the magnitudes of vectors AB and AC, respectively.

To find the vector product (cross product) of the vectors AB and AC, we need to take the cross product between the two vectors. The vector product, denoted as AB × AC, is given by the determinant of the 3x3 matrix formed by the components of the vectors: AB × AC = (yB - yA)(zC - zA) - (zB - zA)(yC - yA), (zB - zA)(xC - xA) - (xB - xA)(zC - zA), (xB - xA)(yC - yA) - (yB - yA)(xC - xA).

The first derivative of the function given in the question is [tex]f(x) = \sqrt(1 - 10x) + (1 - 5x)^2[/tex] is [tex]f'(x) = 2(1 - 5x)\sqrt(1 - 10x) - 10(1 - 5x)(1 - 5x)^2/(5x + 5(x - 3))[/tex].

To differentiate the given function f(x), we need to apply the chain rule and the power rule. Let's break down the function and differentiate each part separately.

[tex]f(x) = \sqrt(1 - 10x) + (1 - 5x)^2[/tex]

First, let's differentiate the square term, [tex](1 - 5x)^2[/tex]. Applying the power rule, we get:

[tex]d/dx[(1 - 5x)^2] = 2(1 - 5x)(-5) = -10(1 - 5x)[/tex]

Next, let's differentiate the square root term, √(1 - 10x). Applying the chain rule, we have:

[tex]d/dx[\sqrt(1 - 10x)] = (1/2)(1 - 10x)^{-1/2}(-10) = -5(1 - 10x)^{-1/2}[/tex]

Now, we can combine the derivatives of both terms to obtain the derivative of f(x):

[tex]f'(x) = -5(1 - 10x)^{-1/2} + -10(1 - 5x)(1 - 5x)[/tex]

Simplifying further:

[tex]f'(x) = -5(1 - 10x)^{-1/2}- 10(1 - 5x)^2[/tex]

To express the answer in a different form, we can factor out a common term from the second part:

[tex]f'(x) = -5(1 - 10x)^{-1/2}- 10(1 - 5x)(1 - 5x)/(5x + 5(x - 3))[/tex]

Thus, the derivative of f(x) is [tex]f'(x) = 2(1 - 5x)\sqrt(1 - 10x) - 10(1 - 5x)(1 - 5x)^2/(5x + 5(x - 3))[/tex].

The indefinite integral of √(x)√(4x² + 81) is (1/12) (4x² + 81)^(3/2) / (x√(x)) + C, where C is the constant of integration.

To find the indefinite integral of √(x)√(4x² + 81), we can use the substitution method. Let's proceed with the following steps:

Step 1: Make a substitution:

Let u = 4x² + 81. Now, differentiate both sides of this equation with respect to x:

du/dx = 8x.

Step 2: Solve for dx:

Rearrange the equation to solve for dx:

dx = du / (8x).

Step 3: Rewrite the integral:

Substitute the value of dx and the expression for u into the integral:

∫(1/√(x)√(4x² + 81)) dx = ∫(1/√(x)√u) (du / (8x)).

Step 4: Simplify the expression:

Combine the terms and simplify the integral:

(1/8)∫(1/√(x)√u) (1/x) du.

Step 5: Separate the variables:

Split the fraction into two separate fractions:

(1/8)∫(1/√(x)√u) (1/x) du = (1/8)∫(1/√(x)x√u) du.

Step 6: Integrate:

Now, we can integrate with respect to u:

(1/8)∫(1/√(x)x√u) du = (1/8)∫(1/√(x)) (√u/x) du.

Step 7: Simplify further:

Move the constant (1/8) outside the integral and rewrite the expression:

(1/8)∫(1/√(x)) (√u/x) du = (1/8√(x)) ∫(√u/x) du.

Step 8: Integrate the remaining expression:

Integrate (√u/x) with respect to u:

(1/8√(x)) ∫(√u/x) du = (1/8√(x)) ∫(1/x)(√u) du.

Step 9: Simplify and solve the integral:

Move the constant (1/8√(x)) outside the integral and integrate:

(1/8√(x)) ∫(1/x)(√u) du = (1/8√(x)) ∫(√u)/x du = (1/8√(x)) (1/x) ∫√u du.

Step 10: Integrate the remaining expression:

Integrate √u with respect to u:

(1/8√(x)) (1/x) ∫√u du = (1/8√(x)) (1/x) * (2/3) u^(3/2) + C.

Step 11: Substitute back the original expression for u:

Substitute u = 4x² + 81:

(1/8√(x)) (1/x) * (2/3) (4x² + 81)^(3/2) + C.

Step 12: Simplify further if needed:

Simplify the expression if desired:

(1/12) (4x² + 81)^(3/2) / (x√(x)) + C.

Therefore, the indefinite integral of √(x)√(4x² + 81) is (1/12) (4x² + 81)^(3/2) / (x√(x)) + C.

There are 91 ways to select 7 plants if 1 rye plant is to be included.

If 1 rye plant is to be included in the selection of 7 plants, there are two cases to consider: selecting the remaining 6 plants from the remaining wheat and barley plants, or selecting the remaining 6 plants from the remaining wheat, barley, and rye plants.

Case 1: Selecting 6 plants from the remaining wheat and barley plants

There are 4 wheat plants and 3 barley plants remaining, making a total of 7 plants. We need to select 6 plants from these 7. This can be calculated using combinations:

Number of ways = C(7, 6) = 7

Case 2: Selecting 6 plants from the remaining wheat, barley, and rye plants

There are 4 wheat plants, 3 barley plants, and 2 rye plants remaining, making a total of 9 plants. We need to select 6 plants from these 9. Again, we can calculate this using combinations:

Number of ways = C(9, 6) = 84

Therefore, the total number of ways to select 7 plants if 1 rye plant is to be included is the sum of the number of ways from both cases:

Total number of ways = Number of ways in Case 1 + Number of ways in Case 2

Total number of ways = 7 + 84

The nth-order Taylor polynomials of the function f(x) = 13ln(x) centered at a = 1, for n = 0, 1, and 2, are as follows:

a) For n = 0, the zeroth-order Taylor polynomial is simply the value of the function at the center: P0(x) = f(a) = f(1) = 13ln(1) = 0. b) For n = 1, the first-order Taylor polynomial is obtained by taking the derivative of the function and evaluating it at the center: P1(x) = f(a) + f'(a)(x - a) = f(1) + f'(1)(x - 1) = 0 + (13/x)(x - 1) = 13(x - 1). c) For n = 2, the second-order Taylor polynomial is obtained by taking the second derivative of the function and evaluating it at the center: P2(x) = f(a) + f'(a)(x - a) + (1/2)f''(a)(x - a)^2 = f(1) + f'(1)(x - 1) + (1/2)(-13/x^2)(x - 1)^2 = 13(x - 1) - (13/2)(x - 1)^2.

a. Approximately 84% of newborns have a respiratory rate within 1.2 standard deviations of the mean.

b. The probability that a newborn selected at random will have a respiratory rate higher than 55 beats per minute is approximately 15.87%.

c. Thirty percent of all newborns have a respiratory rate lower than approximately 47.38 breaths per minute.

d. Approximately 81.33% of samples of 5 newborns will have an average respiratory rate below 52 breaths per minute.

e. Approximately 10.2% of samples of 10 newborns will have an average respiratory rate above 52 breaths per minute.

f. Approximately 39.76% of samples of 10 newborns will have an average respiratory rate between 50 and 52 breaths per minute.

a. 84% of babies have respiratory rates within 1.2 standard deviations of the mean. The normal distribution can calculate this. Finding the area under the normal curve between 1.2 standard deviations above and below the mean gives us the proportion. The proportion of infants in this range is this area.

b. Calculate the area under the normal curve to the right of 55 to discover the probability that a randomly picked infant will have a respiratory rate higher than 55 beats per minute. The z-score formula (x - mean) / standard deviation helps standardise 55. The z-score is 55 - 50 / 5 = 1. Using a calculator or typical normal distribution table, the likelihood of a z-score larger than 1 is 0.1587. The probability is 15.87%, or 0.1587.

c. The 30th percentile z-score determines the respiratory rate below which 30% of neonates fall. 30th percentile z-score is -0.524. A conventional normal distribution table or calculator can identify the z-score associated with an area of 0.3 to the left of it. Multiplying the z-score by the standard deviation and adding it to the mean returns it to its original units. The respiratory rate is (z-score * standard deviation) + mean = (-0.524 * 5) + 50 = 47.38. 30% of neonates breathe less than 47.38 breaths per minute.

d. The average respiratory rate of 5 newborns will follow a normal distribution with the same mean but a standard deviation equal to the population standard deviation divided by the square root of the sample size, which is 5/sqrt(5) = 2.236. To compute the proportion of samples having an average respiratory rate < 52 breaths per minute, we require the z-score. The z-score is 0.8944. The likelihood of a z-score less than 0.8944 is around 0.8133 using a basic normal distribution table or calculator. Thus, 81.33% of 5 newborn samples will have a respiratory rate below 52 breaths per minute.

e. The average respiratory rate of 10 infants will follow a normal distribution with the same mean but a standard deviation of 5/sqrt(10) = 1.5811. We calculate the z-score using (52 - 50) / 1.5811 = 1.2649. The likelihood of a z-score larger than 1.2649 is 0.102. Thus, 10.2% of 10 babies will have a respiratory rate exceeding 52 breaths per minute.

f. Calculate the z-scores for both values to find the fraction of 10 babies with an average respiratory rate between 50 and 52 breaths per minute. (50 - 50) / 1.5811 = 0. (52 - 50) / 1.5811 = 1.2649. The chance of z-scores between 0 and 1.2649 is approximately 0.3976 using a basic normal distribution table or calculator. Thus, 39.76% of 10 newborn samples will have an average respiratory rate of 50–52 breaths per minute.

The limit of the given function as x approaches infinity is 3/2. Let's evaluate the limit of the function as x approaches infinity. We have

lim(x→∞) [(9x² - x) / (6x² + 5x - 8)].

To simplify the expression, we divide the leading term in the numerator and denominator by the highest power of x, which is x². This gives us lim(x→∞) [(9 - (1/x)) / (6 + (5/x) - (8/x²))].

As x approaches infinity, the terms (1/x) and (8/x²) tend to zero, since their denominators become infinitely large. Therefore, we can simplify the expression further as lim(x→∞) [(9 - 0) / (6 + 0 - 0)].

Simplifying this, we get lim(x→∞) [9 / 6]. Evaluating this limit gives us the final result of 3/2.

Keshawn's age is 8, and since Alexa's age is consecutive and even, her age would be 8 + 2 = 10.

What is consecutive even integers?

Cοnsecutive even integers are even integers that fοllοw each οther by a difference οf 2. If x is an even integer, then x + 2, x + 4, x + 6 and x + 8 are cοnsecutive even integers.

Let's assume that Keshawn's age is represented by the variable x. Since their ages are consecutive even integers, Alexa's age would be x + 2.

According to the given information, the sum of the square of Alexa's age and 5 times Keshawn's age is 140. We can express this information in an equation:

(x + 2)² + 5x = 140

Expanding the square term:

x² + 4x + 4 + 5x = 140

Combining like terms:

x² + 9x + 4 = 140

Moving all terms to one side of the equation:

x² + 9x + 4 - 140 = 0

Simplifying:

x² + 9x - 136 = 0

To solve this quadratic equation, we can factor it or use the quadratic formula. Let's use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

For our equation, a = 1, b = 9, and c = -136. Plugging these values into the formula:

x = (-9 ± √(9² - 4 * 1 * -136)) / (2 * 1)

Simplifying further:

x = (-9 ± √(81 + 544)) / 2

x = (-9 ± √625) / 2

x = (-9 ± 25) / 2

We have two possible solutions:

1. x = (-9 + 25) / 2 = 8

2. x = (-9 - 25) / 2 = -17

Since age cannot be negative, we disregard the second solution.

Therefore, Keshawn's age is 8, and since Alexa's age is consecutive and even, her age would be 8 + 2 = 10.

Alexa's age is 10.

The expression (f/m)(x) - (m/f)(x) is calculated by substituting the given functions into the expression and simplifying, resulting in [tex](-x^2 + 3x + 2) / (3x - 6)[/tex], while (f/m)(0) - (m/10) is directly computed as -7/6.

(a) To compute the expression (f/m)(x) - (m/f)(x), we need to substitute the given functions f(x) and m(x) into the expression and simplify.

The expression (f/m)(x) represents f(x) divided by m(x), and (m/f)(x) represents m(x) divided by f(x).

[tex](f/m)(x) = (3x - 6) / (x^2 - 8)[/tex]

[tex](m/f)(x) = (x^2 - 8) / (3x - 6)[/tex]

Substituting the functions into the expression, we have:

[tex](f/m)(x) - (m/f)(x) = (3x - 6) / (x^2 - 8) - (x^2 - 8) / (3x - 6)[/tex]

To simplify this expression further, we can find a common denominator and combine the fractions. However, since the denominator (3x - 6) appears in both terms, we can simplify the expression as follows:

[tex](f/m)(x) - (m/f)(x) = (3x - 6 - (x^2 - 8)) / (3x - 6)[/tex]

Simplifying the numerator, we have:

[tex](3x - 6 - x^2 + 8) / (3x - 6) = (-x^2 + 3x + 2) / (3x - 6)[/tex]

This is the simplified form of the expression (f/m)(x) - (m/f)(x).

(b) To compute the expression (f/m)(0) - (m/10), we need to substitute x = 0 into (f/m)(x) and x = 10 into (m/f)(x) and then perform the subtraction.

Substituting x = 0 into (f/m)(x), we have:

[tex](f/m)(0) = (3(0) - 6) / (0^2 - 8) = -6 / (-8) = 3/4[/tex]

Substituting x = 10 into (m/f)(x), we have:

[tex](m/f)(10) = (10^2 - 8) / (3(10) - 6) = 92 / 24 = 23/6[/tex]

Therefore, (f/m)(0) - (m/10) = (3/4) - (23/6) = (9/12) - (23/6) = (-14/12) = -7/6

In conclusion, the expression (f/m)(x) - (m/f)(x) simplifies to [tex](-x^2 + 3x + 2) / (3x - 6)[/tex], and (f/m)(0) - (m/10) equals -7/6.

The function f(x) = e^x^2 is not injective (one-to-one) on its natural domain because it fails the horizontal line test. This means that there exist different values of x within its domain that map to the same y-value. In other words, there are multiple x-values that produce the same output value.

To find the largest possible domain A, where all elements of A are non-negative and f(x) is defined, we need to consider the domain restrictions of the exponential function. The exponential function e^x is defined for all real numbers, but its output is always positive. Therefore, in order for f(x) = e^x^2 to be non-negative, the values of x^2 must also be non-negative. This means that the largest possible domain A is the set of all real numbers where x is greater than or equal to 0. In interval notation, this can be written as A = [0, +∞). Within this domain, all elements are non-negative, and the function f(x) is well-defined.

The function h(x) = (7:x² – 5)3 can be expressed as the composition of two functions, f(x) and g(x).

Let's break down the process of finding f(x) and g(x) that compose h(x). The given function h(x) can be written as h(x) = (7:(x² – 5))3. We need to determine the inner function g(x) and the outer function f(x) such that h(x) = (f o g)(x).

To simplify the expression, let's start with the inner function g(x) = x² – 5. The function g(x) takes an input, squares it, and then subtracts 5. Next, we determine the outer function f(x) that acts on the output of g(x) to obtain h(x). In this case, f(x) = 7:x, which means it divides 7 by the input. Thus, (f o g)(x) = f(g(x)) = (7:(x² – 5))3.

To illustrate this composition, we first apply the inner function g(x) to the input x. Then, the output of g(x), which is (x² – 5), becomes the input for the outer function f(x). Finally, we raise the result to the power of 3, resulting in the final function h(x) = (7:(x² – 5))3.

Probability that the maximum number of balls in any given box is exactly 22, out of 33 balls distributed in 44 boxes,

To determine the probability, we need to find the favorable outcomes and divide it by the total number of possible outcomes. Since the maximum number of balls in any box should be exactly 22, we distribute 22 balls to one box and distribute the remaining 11 balls among the remaining 43 boxes. This can be represented as choosing 22 balls out of 33 and choosing 11 balls out of the remaining 43. The number of ways to choose these balls can be calculated using combinations.

The probability can be calculated as follows: P(maximum number of balls in any given box = 22) = (Number of favorable outcomes) / (Total number of possible outcomes). The number of favorable outcomes is given by the product of the number of ways to choose 22 balls out of 33 and the number of ways to choose 11 balls out of the remaining 43. The total number of possible outcomes is given by the number of ways to distribute 33 balls among 44 boxes. By calculating the ratios, we can determine the probability that the maximum number of balls in any given box is exactly 22.

By converting the given triple integral into cylindrical coordinates, we can express it as 2r dz dr dθ.

In cylindrical coordinates, we have three variables: r (radius), θ (angle), and z (height). To convert the given integral into cylindrical coordinates, we need to express the differentials of integration (dx, dy, dz) in terms of the cylindrical differentials (dr, dθ, dz).

Starting with I = ∫∫∫ dz dy dx, we can rewrite dx and dy in terms of cylindrical differentials. In cylindrical coordinates, dx = dr cosθ - r sinθ dθ and dy = dr sinθ + r cosθ dθ. Substituting these expressions into the integral, we have I = ∫∫∫ dz (dr cosθ - r sinθ dθ) (dr sinθ + r cosθ dθ).

Simplifying the expression, we obtain I = ∫∫∫ (dr cosθ - r sinθ dθ) (dr sinθ + r cosθ dθ) dz.

Expanding the product, we have I = ∫∫∫ (dr cosθ sinθ + r cos²θ dr dθ - r² sin²θ dθ - r³ sinθ cosθ dθ) dz.

Further simplifying the expression, we can rearrange the terms and factor out common factors to obtain I = ∫∫∫ (r dr dz) (2 cosθ sinθ - r sin²θ - r² sinθ cosθ) dθ.

Finally, we can express the integral as I = ∫∫ (2r cosθ sinθ - r² sin²θ - r³ sinθ cosθ) (dz dr) dθ.

This is the equivalent triple integral in cylindrical coordinates, which can be written as I = ∫∫∫ 2r dz dr dθ.

The integral of [tex]ln(x^2 + 17x + 60)[/tex] with respect to x, when x is greater than 0, evaluates to [tex]2x ln(x + 5) - 2x + C[/tex] , where C represents the constant of integration.

To calculate the integral, we can use the substitution method.

Let [tex]u = x^2 + 17x + 60[/tex].

Then, [tex]du/dx = 2x + 17[/tex],

and solving for dx, we have [tex]dx = du/(2x + 17)[/tex].

Substituting these values into the integral, we get:

[tex]\int\limits{ln(x^2 + 17x + 60) } \,dx = \int\limits ln(u) * (du/(2x + 17))[/tex]

Now, we can separate the variables and rewrite the integral as:

=[tex]\int\limits ln(u) * (1/(2x + 17)) du[/tex]

Next, we can focus on the remaining x term in the denominator. We can rewrite it as follows:

=[tex]\int\limits ln(u) * (1/(2(x + 8.5))) du[/tex]

Pulling the constant factor of 1/2 out of the integral, we have:

=[tex](1/2) * \int\limits ln(u) * (1/(x + 8.5)) du[/tex]

Finally, integrating ln(u) with respect to u gives us:

=[tex](1/2) * (u ln(u) - u) + C[/tex]

Substituting back u = x^2 + 17x + 60, we get the final result:

= [tex]2x ln(x + 5) - 2x + C[/tex]

Therefore, the integral of [tex]ln(x^2 + 17x + 60)[/tex]with respect to x, when x is greater than 0, is [tex]2x ln(x + 5) - 2x + C[/tex], where C represents the constant of integration.

The given series [tex]$\sum_{n=1}^{\infty}(-1)^n(\frac{1}{n})^7$[/tex] converges absolutely and the given series [tex]$\sum_{n=1}^{\infty}n \sin(n)$[/tex] converges conditionally.

Given series [tex]:$\sum_{n=1}^{\infty}(-1)^n(\frac{1}{n})^7$ and $\sum_{n=1}^{\infty}n \sin(n)$First series, $\sum_{n=1}^{\infty}(-1)^n(\frac{1}{n})^7$[/tex]

Here,[tex]$p = 7 > 1$[/tex]

Then by p-series test , the series converges absolutely.

The p-series test states that the infinite series [tex]$\sum_{n=1}^{\infty}\frac{1}{n^p}$[/tex] is convergent if and only if p>1.Second series,[tex]$\sum_{n=1}^{\infty}n \sin(n)$[/tex][tex]$p = 7 > 1$[/tex]

We cannot apply the p-series test or the comparison test, because the series [tex]$\sum_{n=1}^{\infty}n \sin(n)$[/tex]do not have positive terms.So, let's check for the condition of alternating series.

To check the condition of the alternating series, we need to check two conditions: 1. Alternating sign: The series must alternate in sign. That is, the first term must be positive, the second term must be negative, the third term must be positive, and so on.2. Monotonicity: The magnitude of the terms must be monotonically decreasing; that is, $|u_{n+1}| \le |u_{n}|$ for all n.If the two conditions hold, then the series converges.

If the magnitude of the terms does not converge to zero, then the series diverges. Here,[tex]$\sum_{n=1}^{\infty}n \sin(n)$[/tex]satisfies both conditions and hence converges by alternating series test.

Therefore, the given series [tex]$\sum_{n=1}^{\infty}(-1)^n(\frac{1}{n})^7$[/tex] converges absolutely and the given series [tex]$\sum_{n=1}^{\infty}n \sin(n)$[/tex] converges conditionally.

For a sine wave with a period of 3, the value of b can be determined using the formula period = 2π/|b|. In this case, since the given period is 3, we can set up the equation 3 = 2π/|b|.

The period of a sine wave represents the distance required for the wave to complete one full cycle. It is denoted as T and relates to the frequency and wavelength of the wave. The standard formula for a sine wave is y = sin(bx), where b determines the frequency and period. The period is given by the equation period = 2π/|b|.

In this problem, we are given a sine wave with a period of 3. To find the value of b, we can set up the equation 3 = 2π/|b|. By cross-multiplying and isolating b, we find that |b| = 2π/3. Since the absolute value of b can be positive or negative, we consider both cases.

Therefore, the value of b for the given sine wave with a period of 3 is 2π/3 or -2π/3. This represents the frequency of the wave and determines the rate at which it oscillates within the given period.

The series converges for all values of x, the radius of convergence is infinite, and the interval of convergence is (-∞, +∞).

To find the radius of convergence and interval of convergence of the series, we can use the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is L as n approaches infinity, then the series converges if L < 1 and diverges if L > 1.

Let's apply the ratio test to the series ∑((-1)^n * (x-3)^n) / (6n+1):

a(n) = (-1)^n * (x-3)^n / (6n+1)

a(n+1) = (-1)^(n+1) * (x-3)^(n+1) / (6(n+1)+1) = (-1)^n * (-1) * (x-3)^(n+1) / (6n+7)

Now, let's calculate the limit of the absolute value of the ratio:

lim(n→∞) |a(n+1) / a(n)|

= lim(n→∞) |((-1)^n * (-1) * (x-3)^(n+1) / (6n+7)) / ((-1)^n * (x-3)^n / (6n+1))|

= lim(n→∞) |- (x-3) / (6n+7) * (6n+1)|

= lim(n→∞) |- (x-3) / (36n^2 + 48n + 7)|

Since the leading term in the denominator is 36n^2, the limit becomes:

lim(n→∞) |- (x-3) / (36n^2)|

= |x-3| / (36 * lim(n→∞) n^2)

The limit lim(n→∞) n^2 is infinite, so the absolute value of the ratio is:

|a(n+1) / a(n)| = |x-3| / ∞ = 0

Since the limit of the absolute value of the ratio is 0, we have L = 0. Therefore, the series converges for all values of x.

Since the series converges for all values of x, the radius of convergence is infinite, and the interval of convergence is (-∞, +∞).

The solution to the integral equation is y(t) = 5/√5 * sin(√5t).

To solve the integral equation, we take the Laplace transform of both sides. Applying the Laplace transform to the left side, we have L[y(t)] = Y(s), where Y(s) represents the Laplace transform of y(t).

For the right side, we apply the Laplace transform to each term separately. The Laplace transform of 5 is simply 5/s. To evaluate the Laplace transform of the integral term, we can use the convolution property. The convolution of sin(ty(1 - t)) and 1 - t is given by ∫[0 to t] sin(t - τ)y(1 - τ) dτ.

Taking the Laplace transform of sin(t - τ)y(1 - τ), we obtain the expression Y(s) / (s^2 + 1), since the Laplace transform of sin(at) is a / (s^2 + a^2).

Combining the Laplace transforms of each term, we have Y(s) = 5/s - 4Y(s) / (s^2 + 1).

Next, we solve for Y(s) by rearranging the equation: Y(s) + 4Y(s) / (s^2 + 1) = 5/s.

Simplifying further, we have Y(s)(s^2 + 5) = 5s. Dividing both sides by (s^2 + 5), we get Y(s) = 5s / (s^2 + 5).

Finally, we apply the inverse Laplace transform to Y(s) to obtain the solution y(t). Taking the inverse Laplace transform of 5s / (s^2 + 5), we find that y(t) = 5/√5 * sin(√5t).

To find the solution u(t) from the given differential equation and initial condition, we can use the method of separation of variables.

The given differential equation is:

[tex]\(\frac{du}{dt} = e^{3.4t} - 3.2u\)[/tex]

To solve this, we'll separate the variables by moving all terms involving u to one side and all terms involving t to the other side:

[tex]\(\frac{du}{e^{3.4t} - 3.2u} = dt\)[/tex]

Next, we integrate both sides with respect to their respective variables:

[tex]\(\int \frac{1}{e^{3.4t} - 3.2u} du = \int dt\)[/tex]

The integral on the left side is a bit more involved. We can use substitution to simplify it.

Let [tex]\(v = e^{3.4t} - 3.2u\)[/tex], then [tex]\(dv = (3.4e^{3.4t} - 3.2du)\)[/tex].

Rearranging, we have [tex]\(du = \frac{3.4e^{3.4t} - dv}{3.2}\)[/tex].

Substituting these values in, the integral becomes:

Simplifying, we get:

[tex]\(\ln|v| = t + C_1\)[/tex]

where C₁ is the constant of integration.

Substituting back [tex]\(v = e^{3.4t} - 3.2u\)[/tex], we have:

[tex]\(\ln|e^{3.4t} - 3.2u| = t + C_1\)[/tex]

To find the particular solution that satisfies the initial condition u(0) = 3.6, we substitute t = 0 and u = 3.6 into the equation:

The relative minimum value of the function f(x, y) = 3x² + 3y² - 2xy - 7, subject to the constraint 4x + y = 118, is -107.25.

To find the relative minimum of the function f(x, y) subject to the constraint, we can use the method of Lagrange multipliers. The Lagrangian function is defined as L(x, y, λ) = f(x, y) - λ(g(x, y) - 118), where g(x, y) = 4x + y - 118 is the constraint function and λ is the Lagrange multiplier.

To find the critical points, we need to solve the following system of equations:

∂L/∂x = 6x - 2y - 4λ = 0

∂L/∂y = 6y - 2x - λ = 0

g(x, y) = 4x + y - 118 = 0

Solving these equations simultaneously, we get x = -23/3, y = 194/3, and λ = 17/3.

To determine whether this critical point is a relative minimum, we can compute the second partial derivatives of f(x, y) and evaluate them at the critical point. The second partial derivatives are:

∂²f/∂x² = 6

∂²f/∂y² = 6

∂²f/∂x∂y = -2

Evaluating these at the critical point, we find that ∂²f/∂x² = ∂²f/∂y² = 6 and ∂²f/∂x∂y = -2.

Since the second partial derivatives test indicates that the critical point is a relative minimum, we can substitute the values of x and y into the function f(x, y) to find the minimum value:

f(-23/3, 194/3) = 3(-23/3)² + 3(194/3)² - 2(-23/3)(194/3) - 7 = -107.25.

Therefore, the relative minimum value of f(x, y) subject to the constraint 4x + y = 118 is -107.25.
