The first three coefficients are calculated as CO = 1^(3/10), C1 = (3/10) * 1^(-7/10), and C2 = C3 = 0. The interval of convergence for the power series representation of f(x) = 2.0.3 is (-∞, +∞), meaning it converges for all real values of x.

The power series representation of a function involves expressing the function as an infinite sum of terms, where each term is a multiple of x raised to a power. In this case, the function f(x) = 2.0.3 is a constant function with the value of 2.0.3 for all x. To represent it as a power series, we need to find the coefficients cn.

The coefficients cn can be calculated by substituting the corresponding values of n into the formula cn = f^(n)(a) / n!, where f^(n)(a) represents the nth derivative of f(x) evaluated at a, and n! denotes the factorial of n. In this case, since f(x) is a constant function, all its derivatives are zero except for the zeroth derivative, which is simply the function itself.

Calculating the coefficients:

CO: Plugging in n = 0, we get CO = f^(0)(1) / 0! = f(1) = 2.0.3 = 1.

C1: Substituting n = 1, we have C1 = f^(1)(1) / 1! = 0.

C2 and C3: As the function f(x) is a constant, all higher-order derivatives are zero, so C2 = C3 = 0.

The interval of convergence of a power series represents the range of x values for which the series converges. In this case, since all coefficients after C1 are zero, the power series reduces to a constant term, and it converges for all x.

Therefore, the interval of convergence for the power series representation of f(x) = 2.0.3 is (-∞, +∞), meaning it converges for all real values of x.

The atmospheric pressure at an altitude of 12000 ft is approximately 8.333 psi.

Atmospheric pressure refers to the force per unit area exerted by the Earth's atmosphere on any object or surface within it. It is the weight of the air above a specific location, resulting from the gravitational pull on the air molecules. Atmospheric pressure decreases as altitude increases, since there is less air above at higher elevations.

Atmospheric pressure is typically measured using units such as pounds per square inch (psi), millimeters of mercury (mmHg), or pascals (Pa). Standard atmospheric pressure at sea level is defined as 1 atmosphere (atm), which is equivalent to approximately 14.7 psi, 760 mmHg, or 101,325 Pa.

In the problem Given:

P₀ = 15 psi (at sea level)

P(4000 ft) = 12.5 psi

We need to find P(12000 ft).

Using the equation [tex]P = P_0e^{(-kh)[/tex], we can rearrange it to solve for k:

k = -ln(P/P₀)/h

Substituting the given values:

k = -ln(12.5/15)/4000 ft

Now we can use the value of k to find P(12000 ft):

[tex]P(12000 ft) = P_0e^{(-k * 12000 ft)[/tex]

Substituting the calculated value of k and P₀ = 15 psi:

[tex]P(12000 ft) ≈ 15 * e^{(-(-ln(12.5/15)/4000 * 12000) ft[/tex]

Calculating this expression yields P(12000 ft) ≈ 8.333 psi (rounded to three decimal places).

The given ordinary differential equation is a linear homogeneous second-order equation with constant coefficients. The characteristic equation is solved to find the roots, which determine the general solution. To find the particular solution, a guess is made based on the form of the forcing term. The solutions are then combined to form the complete solution. In this case, the complete solution consists of the general solution and the particular solution.

To classify the given ODE, we look at its highest-order derivative term. Since it is a second-order derivative, the ODE is a second-order equation.

The characteristic equation is obtained by substituting y = e^(rx) into the homogeneous form of the equation (setting the forcing term equal to zero). For the given ODE, the characteristic equation becomes:

r^2 + 2r + 17 = 0

Solving this quadratic equation gives us the roots r1 = -1 + 4i and r2 = -1 - 4i.

The general solution to the homogeneous equation is then given by:

y_h(x) = c1e^((-1+4i)x) + c2e^((-1-4i)x)

To find the particular solution, a guess is made based on the form of the forcing term. Since the forcing term is 60e^(-4x)sin(5x), a particular solution of the form y_p(x) = Ae^(-4x)sin(5x) + Be^(-4x)cos(5x) is assumed.

By substituting this guess into the original ODE and solving for A and B, we can find the particular solution.

To ensure that we have found all the solutions, we combine the general solution and the particular solution. The general solution is a linear combination of two linearly independent solutions, and the particular solution is added to this to obtain the complete solution.

Therefore, the complete solution to the given ODE consists of the general solution and the particular solution.

b) The height of the math book at different time intervals can be determined using the formula f(t) = 300 - 9t^2. In the given table, the values of t represent the time in seconds, and the corresponding values of f(t) represent the height in feet.

The first paragraph summarizes the answer: The table shows the height of a math book at different time intervals after being dropped from a high tower. The values in the table were calculated using the formula f(t) = 300 - 9t^2.

The second paragraph provides an explanation of the answer: The formula f(t) = 300 - 9t^2 represents the height of the math book at time t. When t is zero (t = 0), it indicates the initial time when the book was dropped. Substituting t = 0 into the formula gives f(0) = 300 - 9(0)^2 = 300. Therefore, at the start, the math book is at a height of 300 feet.

By substituting the given values of t into the formula, we can calculate the corresponding heights. For example, substituting t = 1 gives f(1) = 300 - 9(1)^2 = 291, meaning that after 1 second, the book is at a height of 291 feet. The process is repeated for each value of t in the table, providing the corresponding heights at different time intervals.

The table serves as a visual representation of the heights of the math book at various time intervals, allowing us to observe the decrease in height as time progresses.

The largest value of a such that cos(x) is decreasing on the interval [0, a],   a = π/2.

To determine the largest value of "a" such that cos(x) is decreasing on the interval [0, a], we need to find the point where the derivative of cos(x) changes from negative to non-negative.

The derivative of cos(x) is given by -sin(x). When cos(x) is decreasing, -sin(x) should be negative. Therefore, we need to find the largest value of "a" such that sin(x) > 0 for all x in the interval [0, a].

The sine function, sin(x), is positive in the interval [0, π/2]. Therefore, the largest value of "a" that satisfies sin(x) > 0 for all x in [0, a] is a = π/2.

Hence, the largest value of "a" such that cos(x) is decreasing on the interval [0, a] is a = π/2.

To linearize the given differential equations, we need to find the linear approximation of the nonlinear terms. In the first equation, the linearization involves finding the first derivative of y with respect to t, while in the second equation, we use logarithmic differentiation to linearize the nonlinear term. In both cases, the linearized equations help approximate the behavior of the original nonlinear equations.

a) To linearize the equation dy/dt + zy = r, we can write the linearized equation as d(y - y0)/dt + z(y - y0) = r - r0, where y0 and r0 are the values of y and r at a specific point. This linearization approximates the behavior of the original equation around the point (y0, r0). The linearization involves finding the first derivative of y with respect to t.

b) To linearize the equation dy/dt + ay + By^2 + yln(y) = Q, we can use logarithmic differentiation. Taking the natural logarithm of both sides of the equation, we get ln(dy/dt) + ln(y) + ln(a) + ln(B) + yln(y) = ln(Q). Then, we differentiate both sides with respect to t, resulting in 1/(y^2) * (dy/dt) + (1/y) * (dy/dt) + (1/y) * y + 0 + yln(y) * (dy/dt) = 0. This linearization allows us to approximate the behavior of the original nonlinear equation by neglecting higher-order terms.

Carmel left for a business trip at 6:00 am, driving her car at a speed of 45 km/hr. At 6:20 am, her son Mot realized she had left a bag behind and took a cab to catch up with her.

Let's denote the time it takes for Mot to catch up with Carmel as t. From 6:00 am to the time of the catch-up, Carmel has been driving for t hours at a speed of 45 km/hr, covering a distance of 45t km. Mot, on the other hand, started at 6:20 am and has been traveling for t hours at a speed of 65 km/hr, covering a distance of 65t km.

For Mot to catch up with Carmel, the distances covered by both should be equal. Therefore, we can set up the equation 45t = 65t to find the value of t. By solving this equation, we can determine the time it takes for Mot to catch up with Carmel.

45t = 65t

20t = 0

t = 0

The equation yields 0 = 0, which means t can take any value since both sides of the equation are equal. Therefore, Mot catches up with Carmel immediately at the time he starts his journey, which is 6:20 am.

Hence, Mot catches up with Carmel at 6:20 am.

The slope of the tangent line to the graph of f(x) = x² - 9 at the point P(-5, 16) is 2a - 10, which simplifies to -20.

To determine the slope of the tangent line at point P, we can use the definition of the derivative.

The derivative of a function f(x) at a point a, denoted as f'(a) or dy/dx|a, represents the slope of the tangent line to the graph of f(x) at that point. In this case, we need to find f'(-5).

Using the power rule of differentiation, the derivative of f(x) = x² - 9 is given by f'(x) = 2x. Substituting x = -5 into this derivative expression, we have [tex]f'(-5) = 2(-5) = -10[/tex].

Therefore, the slope of the tangent line to the graph of f(x) = x² - 9 at the point P(-5, 16) is -10.

To determine the equation of the tangent line at point P, we can use the point-slope form of a linear equation.

The equation of a line with slope m passing through the point (x₁, y₁) is given by [tex]y - y_1 = m(x - x_1)[/tex]. Substituting the values x₁ = -5, y₁ = 16, and m = -10, we have:

[tex]y - 16 = -10(x + 5)[/tex]

Simplifying this equation, we get:

[tex]y - 16 = -10x - 50[/tex]

Finally, rearranging the equation to slope-intercept form, we have:

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:

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.

The critical point of the function f(x) = x² - 8x + 11 is x = 4, and f(4) = -5. The function values at the endpoints of the interval (0, 8) are f(0) = 11 and f(8) = -21. The minimum value of f(x) on the interval (0, 8) is -21, and the maximum value is 11. For the interval (0, 1], the minimum value of f(x) is 4 and the maximum value is 4.

To find the critical point of the function f(x), we need to find the derivative f'(x) and set it equal to zero.

Taking the derivative of f(x) = x² - 8x + 11 gives f'(x) = 2x - 8.

Setting this equal to zero, we get 2x - 8 = 0, which simplifies to x = 4.

Therefore, the critical point is x = 4.

To compute f(c), we substitute c = 4 into the function f(x) and calculate f(4) = 4² - 8(4) + 11 = -5.

Next, we evaluate the function at the endpoints of the interval (0, 8). f(0) = 0² - 8(0) + 11 = 11, and f(8) = 8² - 8(8) + 11 = -21.

The minimum and maximum values of f(x) on the interval (0, 8) can be found by comparing the function values at critical points and endpoints. The minimum value is -21, which occurs at x = 8, and the maximum value is 11, which occurs at x = 0.

For the interval (0, 1], the minimum value of f(x) is 4, which occurs at x = 1, and the maximum value is also 4, which is the same as the minimum value.

The answer to the problem is 0, since both the numerator and the denominator of the expression approach 0 as x approaches 10.

The given limit problem can be solved using the algebraic manipulation of limits. First, let's consider the limit of the function f(x) = 1024 as x approaches 10. From the definition of limit, we can say that as x gets closer and closer to 10, f(x) gets closer and closer to 1024. Therefore, lim f(x) = 1024 as x approaches 10. Next, let's evaluate the limit of the expression (x-10)/(1024-10) as x approaches 10. This can be simplified by factoring out (x-10) from both the numerator and the denominator, which gives (x-10)/(1014). As x approaches 10, this expression also approaches (10-10)/(1014) = 0/1014 = 0. Therefore, lim (x-10)/(1024-10) = 0 as x approaches 10.
Finally, we can use the product rule of limits to find the limit of the expression 5√(x) * (x-10)/(1024-10) as x approaches 10. This rule states that if lim g(x) = L and lim h(x) = M, then lim g(x) * h(x) = L * M. Applying this rule, we get lim 5√(x) * (x-10)/(1024-10) = lim 5√(x) * lim (x-10)/(1024-10) = 5√(10) * 0 = 0.Therefore,The answer to the problem is 0, since both the numerator and the denominator of the expression approach 0 as x approaches 10.

The equation of the tangent line to the graph of the function f(x) = (2x - 1)^4 at x = 1 is y = 8x - 7.

To find the equation of the tangent line to the graph of the function f(x) = (2x - 1)^4 at x = 1, we need to find the slope of the tangent line and the point where it intersects the graph.

Slope of the tangent line:

To find the slope of the tangent line, we need to find the derivative of the function f(x). Taking the derivative of (2x - 1)^4 using the chain rule, we have:

f'(x) = 4(2x - 1)^3 * 2 = 8(2x - 1)^3

Evaluate f'(x) at x = 1:

f'(1) = 8(2(1) - 1)^3 = 8(1)^3 = 8

So, the slope of the tangent line is 8.

Point of tangency:

To find the point where the tangent line intersects the graph, we need to evaluate the function f(x) at x = 1:

f(1) = (2(1) - 1)^4 = (2 - 1)^4 = 1^4 = 1

So, the point of tangency is (1, 1).

Equation of the tangent line:

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

y - y₁ = m(x - x₁)

where (x₁, y₁) is the point of tangency and m is the slope.

Plugging in the values, we have:

y - 1 = 8(x - 1)

Simplifying, we get:

y - 1 = 8x - 8

y = 8x - 7

Therefore, the equation of the tangent line to the graph of f(x) = (2x - 1)^4 at x = 1 is y = 8x - 7.

The question is incomplete and the complete question is shown in the attached picture.

To find the equation of the tangent line to the curve at the point x = 2, we need to find the slope of the curve at that point and use the point-slope form of a line.

To find the slope of the curve at x = 2, we can take the derivative of the original function with respect to x. Once we have the derivative, we evaluate it at x = 2 to find the slope of the tangent line.

After finding the slope, we use the point-slope form of a line, which is y - y1 = m(x - x1), where (x1, y1) is the given point (x = 2) on the curve and m is the slope of the tangent line. Substitute the values of x1, y1, and m into the equation to obtain the equation of the tangent line.

Applying the product rule and the chain rule will allow us to determine the derivative of the given function, "y = 6x2(1 - 5x)".

Let's first give the two elements their formal names: (u = 6x2) and (v = 1 - 5x).

The derivative of (y) with respect to (x) is obtained by (y' = u'v + uv') using the product rule.

Both the derivatives of (u) and (v) with respect to (x) are (u' = 12x) and (v' = -5), respectively.

When these values are substituted, we get:

\(y' = (12x)(1 - 5x) + (6x^2)(-5)\)

Simplifying even more

\(y' = 12x - 60x^2 - 30x^2\)

combining comparable phrases

\(y' = 12x - 90x^2\)

As a result, y' = 12x - 90x2 is the derivative of the function (y = 6x2(1 - 5x)) with respect to (x).

The expectation of the number of points that Sam will score from 3 throws can be calculated by multiplying the number of throws (3) by the probability of scoring a point in each throw (2/3).

To find the expectation, we multiply the number of trials (in this case, the number of throws) by the probability of success in each trial. In this scenario, Sam has a 2/3 chance of scoring a point in each throw. Since there are 3 throws, we can calculate the expectation as follows:

Expectation = Number of throws * Probability of success

Expectation = 3 * (2/3)

Expectation = 2

Therefore, the expectation of the number of points that Sam will score from 3 throws is 2. This means that, on average, we can expect Sam to score 2 points out of 3 throws based on the given probability of success for each throw.

The function y = e^(3x) + 4 has two transformations relative to the parent function, which is the exponential function. The first transformation is a horizontal stretch by a factor of 1/3, and the second transformation is a vertical shift upward by 4 units. These transformations do not have an effect on the derivative of the function.

The parent function of the given equation is the exponential function y = e^x. By comparing it to the given function y = e^(3x) + 4, we can identify two transformations.

The first transformation is a horizontal stretch. The original exponential function has a base of e, which represents natural growth. In the given function, the base remains e, but the exponent is 3x instead of just x. This means that the x-values are multiplied by 3, resulting in a horizontal stretch by a factor of 1/3. This transformation affects the shape of the graph but does not have an effect on the derivative. The derivative of e^x is also e^x, and when we differentiate e^(3x), we still get e^(3x).

The second transformation is a vertical shift. The parent exponential function has a y-intercept at (0, 1). However, in the given function, we have y = e^(3x) + 4. The "+4" term shifts the entire graph vertically upward by 4 units. This transformation changes the position of the function but does not affect its rate of change. The derivative of e^x is e^x, and when we differentiate e^(3x) + 4, the derivative remains e^(3x).

In conclusion, the function y = e^(3x) + 4 has two transformations relative to the parent exponential function. The first transformation is a horizontal stretch by a factor of 1/3, and the second transformation is a vertical shift upward by 4 units. Neither of these transformations has an effect on the derivative of the function.

To evaluate the surface integral ∮S F · dS, where F(x, y, z) = (3.02 - Vy^2 + z^2, sin(x - 2), e^(-2z)), and S is the surface that is the boundary of the region between the sphere x^2 + y^2 + z^2 = 4 and the cone z^2 = 2y^2, we need to parameterize the surface S and calculate the dot product F · Answer :  dS.= (3.02 - V(r^2sin^2ϕ) + z^2, sin(rcosϕ - 2), e^(-2z)) · (cosϕ, sinϕ, 0) dr dϕ

The given region between the sphere and cone can be expressed as S = S1 - S2, where S1 is the surface of the sphere and S2 is the surface of the cone.

Let's start by parameterizing the surfaces S1 and S2:

For S1, we can use spherical coordinates:

x = 2sinθcosϕ

y = 2sinθsinϕ

z = 2cosθ

For S2, we can use cylindrical coordinates:

x = rcosϕ

y = rsinϕ

z = z

Now, let's calculate the dot product F · dS for each surface:

For S1:

F · dS = F(x, y, z) · (dx, dy, dz)

      = (3.02 - V(y^2) + z^2, sin(x - 2), e^(-2z)) · (∂x/∂θ, ∂y/∂θ, ∂z/∂θ) dθ dϕ

      = (3.02 - V(4sin^2θsin^2ϕ) + 4cos^2θ, sin(2sinθcosϕ - 2), e^(-2(2cosθ))) · (2cosθcosϕ, 2cosθsinϕ, -2sinθ) dθ dϕ

For S2:

F · dS = F(x, y, z) · (dx, dy, dz)

      = (3.02 - V(y^2) + z^2, sin(x - 2), e^(-2z)) · (∂x/∂r, ∂y/∂r, ∂z/∂r) dr dϕ

      = (3.02 - V(r^2sin^2ϕ) + z^2, sin(rcosϕ - 2), e^(-2z)) · (cosϕ, sinϕ, 0) dr dϕ

Now, we can integrate the dot product F · dS over the surfaces S1 and S2 using the parameterizations we derived and the appropriate limits of integration. The limits of integration will depend on the region between the sphere and cone in the xy-plane.

Please provide the limits of integration or any additional information about the region between the sphere and cone in the xy-plane so that I can assist you further in evaluating the surface integral.

The expression for dx/dy is [tex](e^y - x) / y[/tex]. Implicit differentiation allows us to find the derivative of a function that is not explicitly defined in terms of a single variable.

To determine dx/dy using implicit differentiation, we need to differentiate both sides of the equation [tex]xy + e^x = e^y[/tex] with respect to y.

Differentiating the left side, we use the product rule:

[tex]d/dy(xy) + d/dy(e^x) = d/dy(e^y)[/tex].

Using the chain rule, d/dy(xy) becomes x(dy/dy) + y(dx/dy).

The derivative of [tex]e^x[/tex] with respect to y is 0, since x is not a function of y. The derivative of [tex]e^y[/tex] with respect to y is e^y.

Combining these results, we have:

x(dy/dy) + y(dx/dy) + 0 = [tex]e^y[/tex].

Simplifying, we get:

x + y(dx/dy) =[tex]e^y[/tex].

Finally, solving for dx/dy, we have:

dx/dy = [tex](e^y - x) / y[/tex].

So, the expression for dx/dy is [tex](e^y - x) / y[/tex]. Implicit differentiation allows us to find the derivative of a function that is not explicitly defined in terms of a single variable.

It involves differentiating both sides of an equation with respect to the appropriate variables and applying the rules of differentiation. In this case, we differentiated the equation [tex]xy + e^x = e^y[/tex] with respect to y to find dx/dy.

The power series solution of the initial value problem y'' - 4y = 0 is y(x) = 0.

The Lagrange inversion theorem can be used to find the power series expansion of an analytic function's inverse function. behaviour close to the border. At any location inside the disc of convergence, the sum of a power series with a positive radius of convergence is an analytical function.

To find the power series solution of the initial value problem y'' - 4y = 0, we can assume a power series representation for y(x) and substitute it into the differential equation.

Let's assume that y(x) can be written as a power series in terms of x:

y(x) = ∑[n=0 to ∞] aₙxⁿ,

where aₙ are coefficients to be determined.

First, we differentiate y(x) with respect to x:

y'(x) = ∑[n=0 to ∞] aₙnxⁿ⁻¹,

and then differentiate again:

y''(x) = ∑[n=0 to ∞] aₙn(n-1)xⁿ⁻².

Now, we substitute these expressions for y(x), y'(x), and y''(x) into the differential equation:

∑[n=0 to ∞] aₙn(n-1)xⁿ⁻² - 4∑[n=0 to ∞] aₙxⁿ = 0.

Next, we collect terms with the same power of x:

a₀(0)(-1)x⁻² + a₁(1)(0)x⁻¹ + a₂(2)(1)x⁰ + ∑[n=3 to ∞] (aₙn(n-1)xⁿ⁻² - 4aₙxⁿ) = 0.

Simplifying further, we obtain:

a₂x⁰ + ∑[n=3 to ∞] [(aₙn(n-1) - 4aₙ)xⁿ - a₀x⁻² - a₁x⁻¹] = 0.

For this equation to hold for all values of x, each term in the series must be zero. We can set the coefficients of each term to zero to obtain a set of recurrence relations:

a₂ = 0,

aₙn(n-1) - 4aₙ = 0, for n ≥ 3,

a₀ = 0,

a₁ = 0.

From the recurrence relation, we can see that aₙ = 0 for all n ≥ 3, and a₀ = a₁ = a₂ = 0.

Therefore, the power series solution of the initial value problem y'' - 4y = 0 is y(x) = 0.

The complete solution to the integral ∫(x³)/√(x² + 9) dx using trigonometric substitution is:

∫(x³)/√(x² + 9) dx = 27 tanθ - 27 ln |sec θ| + C

First, substitute x = 3tanθ.

let the derivative of x = 3tanθ with respect to θ:

dx/dθ = 3sec²θ

Solving for dx, we get:

dx = 3sec²θ dθ

Now let's substitute x and dx in terms of θ:

x = 3 tanθ

dx = 3 sec²θ dθ

Next, we need to express (x³)/√(x² + 9) in terms of θ:

(x³)/√(x² + 9)  

= (3 tan θ)³/√((3 tan θ)² + 9)

= 27 tan³ θ/√(9tan²θ + 9)

= 27 tan³ θ/√9(tan²θ + 1)

Now we can rewrite the integral using the new variables:

∫(x³)/√(x² + 9)  dx

= ∫27 tan³ θ/√9(tan²θ + 1)) 3sec²θ dθ

= 81 ∫ tan³3 θ sec θ /√(9 sec² θ) dθ

= 81 ∫ tan³ θ sec θ/ 3 sec θ dθ

= 27 ∫ tan³θ dθ

Using the identity tan²θ = sec²θ - 1, we can rewrite the integral as:

27∫tan³θ dθ = 27∫(tan²θ)(tanθ) dθ

= 27∫(sec²θ - 1)(tanθ) dθ

= 27∫(sec²θ)(tanθ) - 27∫(tanθ) dθ

The first integral can be solved by using the substitution u = tanθ, which gives du = sec²θ dθ:

27∫du - 27∫(tanθ) dθ

The first integral becomes a simple integration:

27u - 27∫(tanθ) dθ

Now, we can evaluate the second integral:

27u - 27 ln |sec θ| + C

Finally, substituting again u = tanθ:

27tanθ - 27 ln |sec θ| + C

Therefore, the complete solution to the integral ∫(x³)/√(x² + 9) dx using trigonometric substitution is:

∫(x³)/√(x² + 9) dx = 27 tanθ - 27 ln |sec θ| + C

The general antiderivative of the acceleration function a(t) = -32 is given by integrating with respect to time:

v(t) = ∫(-32) dt = -32t + C

Given that v(0) = 20, we can substitute t = 0 and v(t) = 20 into the velocity equation and solve for C:

20 = -32(0) + C

C = 20

Thus, the exact formula for the velocity v(t) of the shoes at time t after they were thrown is:

v(t) = -32t + 20

To find the general antiderivative of v(t), we integrate the velocity function with respect to time:

s(t) = ∫(-32t + 20) dt = -16t² + 20t + C

Since the shoes were thrown from a window 30 feet above the ground, we set s(0) = 30 and solve for C:

30 = -16(0)² + 20(0) + C

C = 30

Therefore, the equation s(t) that describes the position (height) of the shoes is:
