The divergen theorm also known as Gauss's theorem, is a fundamental theorem in vector calculus that relates the outward flux of a vector field through a closed surface to the divergence of the field inside the surface.

Here, we will use the divergence theorem to evaluate SI F:ds where S -1 = 2 F(x, y, z) = (x +2yz? i + (4y +tan (x?z)) j+(2z+sin-(2xy?)) k and S is the outward-oriented surface of the solid E bounded by the parabolo.The given vector field is F(x, y, z) = (x + 2yz)i + (4y + tan(xz))j + (2z - sin(2xy))k. The solid E is bounded by the paraboloid z = 4 - x² - y² and the plane z = 0. Therefore, the surface S is the boundary of E oriented outward. By the divergence theorem, we know that: ∫∫S F · dS = ∭E ∇ · F dV Here, ∇ · F is the divergence of F. Let's calculate the divergence of F: ∇ · F = (∂/∂x)(x + 2yz) + (∂/∂y)(4y + tan(xz)) + (∂/∂z)(2z - sin(2xy))= 1 + 2y + xzsec²(xz) + 2cos(2xy) Now, using the divergence theorem, we can write: ∫∫S F · dS = ∭E ∇ · F dV= ∭E (1 + 2y + xzsec²(xz) + 2cos(2xy)) dVWe can change the integral to cylindrical coordinates: x = r cosθ, y = r sinθ, and z = z. The Jacobian is r. The bounds for r and θ are 0 to 2 and 0 to 2π, respectively, and the bounds for z are 0 to 4 - r². Therefore, the integral becomes: ∫∫S F · dS = ∭E (1 + 2y + xzsec²(xz) + 2cos(2xy)) dV= ∫₀² ∫₀² ∫₀^(4 - r²) (1 + 2r sinθ + r² cosθ zsec²(r²cosθsinθ)) + 2cos(2r²sinθcosθ)) r dz dr dθThis integral is difficult to evaluate analytically. Therefore, we can use a computer algebra system to get the numerical result.

The mean of the random variable X, denoted by E[X], is 0.44.

To calculate the mean of a discrete random variable using its cumulative distribution function (CDF), we need to use the formula:

E[X] = Σ(x * P(X = x))

Where x represents the possible values of the random variable, and P(X = x) represents the probability mass function (PMF) of the random variable at each x.

Given the cumulative distribution function values, we can determine the PMF as follows:

P(X = -3) = Fx(-3) - Fx(-4) = 0.14 - 0 = 0.14

P(X = -2) = Fx(-2) - Fx(-3) = 0.2 - 0.14 = 0.06

P(X = -1) = Fx(-1) - Fx(-2) = 0.25 - 0.2 = 0.05

P(X = 0) = Fx(0) - Fx(-1) = 0.43 - 0.25 = 0.18

P(X = 1) = Fx(1) - Fx(0) = 0.54 - 0.43 = 0.11

P(X = 2) = Fx(2) - Fx(1) = 1.0 - 0.54 = 0.46

Now we can calculate the mean using the formula mentioned earlier:

E[X] = (-3 * 0.14) + (-2 * 0.06) + (-1 * 0.05) + (0 * 0.18) + (1 * 0.11) + (2 * 0.46)

     = -0.42 - 0.12 - 0.05 + 0 + 0.11 + 0.92

Therefore, the mean of the random variable X, denoted by E[X], is 0.44.

The definite integral used to compute the area bounded between two curves is obtained by taking the limit of a Riemann sum, where the height represents the difference between the upper and lower curves and the thickness represents the width of each rectangle.

To calculate the area between two curves, we divide the interval into small subintervals, each with a width denoted as Δx or Δy. The height of each rectangle is determined by the difference between the upper and lower curves. If the width is in the x-direction (Δx), the height is obtained by subtracting the equation of the lower curve from the equation of the upper curve. On the other hand, if the width is in the y-direction (Δy), the height is obtained by subtracting the equation of the left curve from the equation of the right curve.

By summing up the areas of these rectangles and taking the limit as the width of the subintervals approaches zero, we obtain the definite integral, which represents the area between the two curves.

In conclusion, the definite integral is used to compute the area bounded between two curves by considering the difference between the upper and lower (or left and right) curves as the height of each rectangle and the width of the subintervals as the thickness.

Answer:

x = 7.2 units

Step-by-step explanation:

Because this is a right triangle, we can use trigonometric functions to solve for variable x. We are given an adjacent leg to our triangle, an acute angle, and the hypotenuse so we are going to take the cosine of that angle.

Cosine of an angle equals the adjacent leg divided by the hypotenuse so our equation looks like:
cos 37° = [tex]\frac{x}{9}[/tex]

To isolate variable x we are going to multiply both sides by 9:
9(cos 37°) = 9([tex]\frac{x}{9}[/tex])

Multiply and simplify:
9 cos 37° = 9x / 9
9 cos 37° = 1x
9 cos 37° = x

Break out a calculator and solve, making sure to round to the nearest tenth as the directions say:

Given that sec(θ) = -6/5 and θ terminates in QIII, we can sketch a graph of θ and find the exact values of sin(θ) and cot(θ).

In QIII, both the x-coordinate and y-coordinate of a point on the unit circle are negative.

Since sec(θ) = -6/5, we know that the reciprocal of cosine, which is 1/cos(θ), is equal to -6/5.

From this, we can deduce that cosine is negative, and its absolute value is 5/6.

To find sin(θ), we can use the Pythagorean identity sin^2(θ) + cos^2(θ) = 1.

Plugging in the value of cos(θ) as 5/6, we can solve for sin(θ). In this case,

sin(θ) = -sqrt(1 - (5/6)^2) = -sqrt(11/36) = -sqrt(11)/6.

For cot(θ), we know that cot(θ) = 1/tan(θ). Since cosine is negative in QIII,

we can deduce that tangent is also negative.

Using the identity tan(θ) = sin(θ)/cos(θ), we can calculate tan(θ) = (sqrt(11)/6)/(5/6) = sqrt(11)/5.

Therefore, cot(θ) = 1/tan(θ) = 5/sqrt(11).

In summary, in QIII where sec(θ) = -6/5, sin(θ) = -sqrt(11)/6, and cot(θ) = 5/sqrt(11).

The Maclaurin series representation of f(x) = (x+2)-³ is ∑[((-1)^n)*(n+1)x^n]/2^(n+4).

The MacLaurin series is a special case of the Taylor series in which the approximation of a function is centered at x=0. It can be represented as f(x) = ∑[((d^n)f(0))/(n!)]*(x^n), where d^n represents the nth derivative of f(x), evaluated at x = 0.

To derive the MacLaurin series representation of f(x) = (x+2)-³, we need to find the nth derivative of f(x) and evaluate it at x = 0.

We can use the chain rule and the power rule to find the nth derivative of f(x), which is -6*((x+2)^(-(n+3))). Evaluating this at x = 0 yields (-6/2^(n+3))*((n+2)!), since all the terms containing x disappear and we are left with the constant term.

Now we can substitute this nth derivative into the MacLaurin series formula to get the series representation: f(x) = ∑[((-6/2^(n+3))*((n+2)!))/(n!)]*(x^n). Simplifying this expression yields f(x) = ∑[((-1)^n)*(n+1)x^n]/2^(n+4), which is the desired MacLaurin series representation of f(x) = (x+2)-³.

The first problem asks for the derivative of y = xcos(x) using logarithmic differentiation. The second problem involves finding y' for the function x sin(y) using implicit differentiation.

a. To find the derivative of y = xcos(x) using logarithmic differentiation, we take the natural logarithm of both sides:

ln(y) = ln(xcos(x))

Next, we apply the logarithmic differentiation technique by differentiating implicitly with respect to x:

1/y * dy/dx = (1/x) + (d/dx)(cos(x))

To find dy/dx, we multiply both sides by y:

dy/dx = y * [(1/x) + (d/dx)(cos(x))]

Substituting y = xcos(x) into the equation, we have:

dy/dx = xcos(x) * [(1/x) + (d/dx)(cos(x))]

Simplifying further, we obtain:

dy/dx = cos(x) + x * (-sin(x)) = cos(x) - xsin(x)

Therefore, the derivative of y = xcos(x) using logarithmic differentiation is dy/dx = cos(x) - xsin(x).

b. To find y' for the function x sin(y) using implicit differentiation, we differentiate both sides of the equation with respect to x:

d/dx (x sin(y)) = d/dx (0)

Applying the product rule on the left-hand side, we get:

sin(y) + x * (d/dx)(sin(y)) = 0

Next, we need to find (d/dx)(sin(y)). Since y is a function of x, we differentiate sin(y) using the chain rule:

(d/dx)(sin(y)) = cos(y) * (d/dx)(y)

Simplifying the equation, we have:

sin(y) + xcos(y) * (d/dx)(y) = 0

To isolate (d/dx)(y), we divide both sides by xcos(y):

(d/dx)(y) = -sin(y) / (xcos(y))

Therefore, y' for the function x sin(y) is given by y' = -sin(y) / (xcos(y)).

We are given a line passing through point P (-2, 2, 1) and another line described by the equation L₂: R = (16, 0, -1) + t(1, 2, -2). We need to find the coordinates of a point A on line L₂ such that the line segment AP is perpendicular to line L₂.

To find a point A on line L₂ such that AP is perpendicular to L₂, we need to find the intersection of line L₂ and the line perpendicular to L₂ passing through point P.

The direction vector of line L₂ is (1, 2, -2). To find a vector perpendicular to L₂, we can take the cross product of the direction vector of L₂ and a vector parallel to AP.

Let's take vector AP = (-2 - 16, 2 - 0, 1 - (-1)) = (-18, 2, 2).

Taking the cross product of (1, 2, -2) and (-18, 2, 2), we get (-6, -40, -38).

To find point A, we add the obtained vector to a point on L₂. Let's take the point (16, 0, -1) on L₂.

Adding (-6, -40, -38) to (16, 0, -1), we get A = (10, -40, -39).

a. To sketch the region in quadrant I enclosed by the curves y = 4x, y = 5 - √x, and the y-axis, we can start by plotting the graphs of these equations and identifying the area of overlap.

The region in quadrant I is enclosed by the curves y = 4x, y = 5 - √x, and the y-axis. It consists of the portion between the x-axis and the curves y = 4x and y = 5 - √x.

1. Plotting the Curves:

To sketch the region, we plot the graphs of the equations y = 4x and y = 5 - √x in the first quadrant. The curve y = 4x represents a straight line passing through the origin with a slope of 4. The curve y = 5 - √x is a decreasing curve that starts at the point (0, 5) and approaches the y-axis asymptotically.

2. Identifying the Region:

The region enclosed by the curves and the y-axis consists of the area between the x-axis and the curves y = 4x and y = 5 - √x. This region is bounded by the x-values where the two curves intersect.

3. Determining Intersection Points:

To find the intersection points, we set the equations y = 4x and y = 5 - √x equal to each other:

4x = 5 - √x

16x^2 = 25 - 10√x + x

16x^2 - x - 25 + 10√x = 0

Solving this quadratic equation will give us the x-values where the curves intersect.

b. Finding the Volume of the Solid of Revolution:

To find the volume of the solid of revolution obtained by rotating the region in quadrant I, we can use the method of cylindrical shells or the disk method. The specific method depends on the axis of rotation.

If the region is rotated around the y-axis, we can use the cylindrical shell method. This involves integrating the circumference of each shell multiplied by its height. The height will be the difference between the functions y = 4x and y = 5 - √x, and the circumference will be 2πx.

If the region is rotated around the x-axis, we can use the disk method. This involves integrating the area of each disk formed by taking cross-sections perpendicular to the x-axis. The radius of each disk will be the difference between the functions y = 4x and y = 5 - √x, and the area will be πr^2.

The specific calculation for finding the volume depends on the axis of rotation specified in the problem.

The equation of the line(s) normal to the curve y = (2x - 1)^3 with a slope of -1/24 and x > 0 is y = 12x - 6 - (1/6)i.

To find the equation of the line(s) normal to the curve y = (2x - 1)^3 with a slope of -1/24, we can use the properties of derivatives.

The slope of the normal line to a curve at a given point is the negative reciprocal of the slope of the tangent line to the curve at that point.

First, we need to find the derivative of the given curve to determine the slope of the tangent line at any point.

Let's find the derivative of y = (2x - 1)^3:

dy/dx = 3(2x - 1)^2 * 2

      = 6(2x - 1)^2

Now, let's find the x-coordinate(s) of the point(s) where the derivative is equal to -1/24.

-1/24 = 6(2x - 1)^2

Dividing both sides by 6:

-1/144 = (2x - 1)^2

Taking the square root of both sides:

±√(-1/144) = 2x - 1

±(1/12)i = 2x - 1

For real solutions, we can disregard the complex roots. So, we only consider the positive root:

(1/12)i = 2x - 1

Solving for x:

2x = 1 + (1/12)i

x = (1/2) + (1/24)i

Since we are interested in values of x greater than 0, we discard the solution x = (1/2) + (1/24)i.

Now, we can find the y-coordinate(s) of the point(s) using the original equation of the curve:

y = (2x - 1)^3

Substituting x = (1/2) + (1/24)i into the equation:

y = (2((1/2) + (1/24)i) - 1)^3

  = (1 + (1/12)i - 1)^3

  = (1/12)i^3

  = (-1/12)i

Therefore, we have a point on the curve at (x, y) = ((1/2) + (1/24)i, (-1/12)i).

Now, we can determine the slope of the tangent line at this point by evaluating the derivative:

dy/dx = 6(2x - 1)^2

Substituting x = (1/2) + (1/24)i into the derivative:

dy/dx = 6(2((1/2) + (1/24)i) - 1)^2

      = 6(1 + (1/12)i - 1)^2

      = 6(1/12)i^2

      = -(1/12)

The slope of the tangent line at the point ((1/2) + (1/24)i, (-1/12)i) is -(1/12).

To find the slope of the normal line, we take the negative reciprocal:

m = 12

So, the slope of the normal line is 12.

Now, we have a point on the curve ((1/2) + (1/24)i, (-1/12)i) and the slope of the normal line is 12.

Using the point-slope form of a line, we can write the equation of the normal line:

y - (-1/12)i = 12(x - ((1/2) + (1/24)i))

Simplifying:

y + (1/12)i = 12x - 6 - (1/2)i - (1/2)i

Combining like terms:

y + (1/12)i = 12x - 6 - (1/24)i

To write the equation without complex numbers, we can separate the real and imaginary parts:

y = 12x - 6 - (1/12)i - (1/12)i

The equation of the normal line, in terms of real and imaginary parts, is:

y = 12x - 6 - (1/6)i.

The projection of u onto v can be determined as follows:

Projection of u onto v = [(u.v) / (|v|²)] × v

where u.v represents the dot product of vectors u and v, and |v| represents the magnitude of vector v

Now, u.v = (2 × 8) + (5 × 7)

To find the integral of the expression ∫(x² + sin x) cos a dr, we can break it down into two separate integrals using the linearity property of integration.

The integral of x² cos a dr can be calculated by treating a as a constant and integrating term by term. The integral of x² with respect to r is (1/3) x³, and the integral of cos a with respect to r is sin a multiplied by r. Therefore, the integral of x² cos a dr is (1/3) x³ sin a.

Similarly, the integral of sin x cos a dr can be calculated by treating a as a constant. The integral of sin x with respect to r is -cos x, and multiplying it by cos a gives -cos x cos a.

Combining both integrals, we have (1/3) x³ sin a - cos x cos a. Since the constant of integration can be added to the result, we denote it as C. Therefore, the final answer is x² sin x - 2x cos x - 2 sin x + C.

The probability that all three chosen people are male, we need to determine the number of favorable outcomes (choosing three males) divided by the total number of possible outcomes (choosing any three people from the crowd).

The total number of possible outcomes is given by choosing three people out of the total 5000 people in the stadium, which can be calculated as 5000C3.

The number of favorable outcomes is selecting three males from the 4000 male attendees. This can be calculated as 4000C3.

Therefore, the probability that all three chosen people are male is:

P(all 3 are male) = (number of favorable outcomes) / (total number of possible outcomes)

                 = 4000C3 / 5000C3

To simplify the expression, let's calculate the values of 4000C3 and 5000C3:

4000C3 = (4000!)/(3!(4000-3)!)

= (4000 * 3999 * 3998) / (3 * 2 * 1)

= 8,784,00

5000C3 = (5000!)/(3!(5000-3)!)

= (5000 * 4999 * 4998) / (3 * 2 * 1)

= 208,333,167

Substituting these values into the probability expression:

P(all 3 are male) = 8,784,000 / 208,333,167

to determine the radius of convergence, r, and the interval of convergence, i, of the series σ(n=1 to ∞) (n⁴/5) xⁿ, 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 less than 1, the series converges.

using the ratio test, let's calculate the limit:

lim(n→∞) |[(n+1)⁴/5 * x⁽ⁿ⁺¹⁾] / [(n⁴/5) * xⁿ]|

simplifying:

lim(n→∞) |[(n+1)⁴/5 * x⁽ⁿ⁺¹⁾] / [(n⁴/5) * xⁿ]|

= lim(n→∞) |[(n+1)⁴/5 * x] / [n⁴/5]|

= lim(n→∞) |[(n+1)/n]⁴ * x|

= |x|

the limit of the ratio is |x|. for the series to converge, the absolute value of x must be less than 1. for x = -1, the series becomes:

σ(n=1 to ∞) (n⁴/5) (-1)ⁿ

this is an alternating series. by the alternating series test, we can determine that it converges.

for x = 1, the series becomes:

σ(n=1 to ∞) (n⁴/5)

to determine if this series converges or diverges, we can use the p-series test. the p-series test states that for a series of the form σ(1 to ∞) nᵖ, the series converges if p > 1 and diverges if p ≤ 1. in this case, p = 4/5 > 1, so the series converges.

To establish the identity sin(e)cos(e) - (1 - cot(e)) = cos(e) - sin(e)/(1 + tan(e)), we simplify each side separately.

Left side:

sin(e)cos(e) - (1 - cot(e))

Using the trigonometric identity cot(e) = cos(e)/sin(e), we rewrite the expression as:

sin(e)cos(e) - (1 - cos(e)/sin(e))

Multiply through by sin(e) to eliminate the denominator:

sin^2(e)cos(e) - sin(e) + cos(e)

Right side:

cos(e) - sin(e)/(1 + tan(e))

Using the trigonometric identity tan(e) = sin(e)/cos(e), we rewrite the expression as:

cos(e) - sin(e)/(1 + sin(e)/cos(e))

Multiply through by cos(e) to eliminate the denominator:

cos^2(e) - sin(e)cos(e)/(cos(e) + sin(e))

Now we can compare the simplified left side and right side:

sin^2(e)cos(e) - sin(e) + cos(e) = cos^2(e) - sin(e)cos(e)/(cos(e) + sin(e))

To simplify further, we can use the identity sin^2(e) + cos^2(e) = 1:

(1 - cos^2(e))cos(e) - sin(e) + cos(e) = cos^2(e) - sin(e)cos(e)/(cos(e) + sin(e))

Expanding and rearranging terms:

cos(e) - cos^3(e) - sin(e) + cos(e) = cos^2(e) - sin(e)cos(e)/(cos(e) + sin(e))

Combine like terms:

2cos(e) - cos^3(e) - sin(e) = cos^2(e) - sin(e)cos(e)/(cos(e) + sin(e))

To simplify further, we can divide through by cos(e) + sin(e) (assuming cos(e) + sin(e) ≠ 0):

2 - cos^2(e) - sin^2(e) = cos^2(e) - sin(e)cos(e)/(cos(e) + sin(e))

Using the identity sin^2(e) + cos^2(e) = 1:

2 - 1 = cos^2(e) - sin(e)cos(e)/(cos(e) + sin(e))

1 = cos^2(e) - sin(e)cos(e)/(cos(e) + sin(e))

This confirms that the left side is equal to the right side, establishing the identity.

Therefore, we have established the identity sin(e)cos(e) - (1 - cot(e)) = cos(e) - sin(e)/(1 + tan(e)) in terms of sine and cosine.

a. We can cancel out common terms an+1 / an = -(n+1)(n+1)! / n(n)! = -(n+1) / n

b. The limit as n approaches infinity is -∞.

c. The series n(-7)n! converges according to the ratio test.

When n is large, an is nonzero, and the ratio test is a test (or "criterion") for the convergence of a series where each term is a real or complex integer. The test, often known as d'Alembert's ratio test or the Cauchy ratio test, was first published by Jean le Rond d'Alembert.

To determine whether the series n(-7)n! converges or diverges using the ratio test, let's find the ratio of successive terms. The ratio test states that if the limit of the ratio of consecutive terms is less than 1, the series converges. Otherwise, if the limit is greater than 1 or the limit is equal to 1, the series diverges or the test is inconclusive, respectively.

(a) Find the ratio of successive terms:

an+1 / an = (n+1)(-7)(n+1)! / (n)(-7)(n)! = -(n+1)(n+1)! / n(n)!

To simplify this expression, we can cancel out common terms:

an+1 / an = -(n+1)(n+1)! / n(n)! = -(n+1) / n

(b) Evaluate the limit of the ratio as n approaches infinity:

lim(n->∞) -(n+1) / n = -∞

The limit as n approaches infinity is -∞.

(c) By the ratio test, if the limit of the ratio of consecutive terms is less than 1, the series converges. In this case, the limit is -∞, which is less than 1. Therefore, the series n(-7)n! converges according to the ratio test.

To generate 10 realizations of length n = 200 each of an ARMA (1,1) process with parameters φ = 0.9 and θ = 0.5, we can simulate the process multiple times using these parameter values. By iterating the process equation for each realization and estimating the values of the parameters φ and θ, we can compare the estimated values to the true values of φ = 0.9 and θ = 0.5.

An ARMA (1,1) process is a combination of an autoregressive (AR) component and a moving average (MA) component. The process can be defined as:

X_t = φX_{t-1} + Z_t + θZ_{t-1}

where X_t is the value at time t, φ is the autoregressive parameter, Z_t is the white noise error term at time t, and θ is the moving average parameter.

To generate the realizations, we can start with an initial value X_0 and iterate the process equation for n time steps using the given parameter values. This will give us a series of n values for each realization.

Next, we can estimate the values of the parameters φ and θ for each realization. There are various methods for parameter estimation, such as maximum likelihood estimation or least squares estimation. These methods involve finding the parameter values that maximize the likelihood of observing the given data or minimize the sum of squared errors.

Once we have the estimated parameter values for each realization, we can compare them to the true values (φ = 0.9 and θ = 0.5). We can calculate the difference between the estimated values and the true values to assess the accuracy of the estimators.

By repeating this process for 10 realizations of length 200, we can evaluate the performance of the estimators and assess how close they are to the true values of the parameters.

1.The area of the region bounded by + y = 0 and x = y² + 3y is 9 square units.

2.The area of the region bounded by the parabolas y = r² and y = 2 - 2x can be calculated by finding the points of intersection and integrating the difference between the two functions.

To find the area of the region bounded by + y = 0 and x = y² + 3y, we need to determine the points of intersection between the two curves. Setting y = 0 in the equation x = y² + 3y, we get x = 0. So, the intersection point is (0, 0). Next, we need to find the other intersection point by solving the equation y² + 3y = 0. Factoring y out, we get y(y + 3) = 0, which gives us y = 0 and y = -3. Since y cannot be negative for this problem, the other intersection point is (0, -3). Thus, the region is bounded by the x-axis and the curve x = y² + 3y. To find the area, we integrate the function x = y² + 3y with respect to y over the interval [-3, 0]. The integral is given by ∫(y² + 3y)dy evaluated from -3 to 0. Solving this integral, we get the area of the region as 9 square units.

The base of the solid is the region bounded by the parabolas y = r² and y = 2 - 2x. To find the area of this region, we need to determine the points of intersection between the two curves. Setting the two equations equal to each other, we get r² = 2 - 2x. Rearranging the equation, we have x = (2 - r²)/2. So, the intersection point is (x, y) = ((2 - r²)/2, r²). The region is bounded by the two parabolas, and we need to find the area between them. To do this, we integrate the difference of the two functions, which is given by A = ∫[(2 - 2x) - r²]dx evaluated over the appropriate interval. The interval of integration depends on the range of values for r. Once the integral is solved over the specified interval, we will obtain the area of the region as the final result.

This general solution satisfies the given differential equation y" - 6y + 9y = e³1 t² for t > 0.

The general solution of the given differential equation y" - 6y + 9y = e³1 t² for t > 0 can be obtained using the method of Variation of Parameters. It involves finding particular solutions and then combining them with the complementary solution to obtain the general solution.

To solve the differential equation using Variation of Parameters, we first find the complementary solution by assuming y = e^(rt). Substituting this into the differential equation gives us the characteristic equation r² - 6r + 9 = 0, which factors to (r - 3)² = 0. Hence, the complementary solution is y_c = (c₁ + c₂t)e^(3t).

Next, we find the particular solution using the method of Variation of Parameters.

We assume a particular solution of the form y_p = u₁(t)e^(3t), where u₁(t) is an unknown function.

Differentiating y_p twice, we get y_p'' = (u₁'' + 6u₁' + 9u₁)e^(3t).

Substituting y_p and its derivatives into the differential equation, we obtain u₁''e^(3t) = e³1 t².

To determine u₁(t), we solve the following system of equations: u₁'' + 6u₁' + 9u₁ = t² and u₁''e^(3t) = e³1 t².

By solving this system, we find u₁(t) = (1/9)t⁴e^(-3t).

Finally, the general solution is obtained by combining the complementary and particular solutions: y = y_c + y_p = (c₁ + c₂t)e^(3t) + (1/9)t⁴e^(-3t).

This general solution satisfies the given differential equation y" - 6y + 9y = e³1 t² for t > 0.
