The term of geometric sequence is equal 9th term.

To find the term of the geometric sequence that is equal to 48,828,125, we can determine the common ratio of the sequence first.

The 4th term is 625, and the 5th term is 3,125.

We can find the common ratio (r) by dividing the 5th term by the 4th term:

r = 3,125 / 625 = 5

Now that we know the common ratio is 5, we can find the desired term by performing the following steps:

Determine the exponent (n) by taking the logarithm base 5 of 48,828,125:

n = log base 5 (48,828,125) ≈ 8

Add 1 to the exponent to account for the term indexing starting from 1:

n + 1 = 8 + 1 = 9

Therefore, the term of the geometric sequence that is equal to 48,828,125 is the 9th term.

The volume of the solid generated by revolving the plane region about the x-axis is 96π/5 units cubed.

Given the plane region bounded by the curves y = x³, y = 0, and y = 8, we want to rotate this region about the x-axis.

The general formula for the volume using the shell method is:

V = 2π ∫[a,b] (radius) * (height) * dx

In this case, the radius is the x-coordinate, and the height is the difference between the upper and lower curves.

To determine the limits of integration [a, b], we need to find the x-values where the curves intersect. Setting y = x³ and y = 8 equal to each other, we can solve for x:

x³ = 8

x = 2

So, the limits of integration are [a, b] = [0, 2].

Now, we can set up the integral for the volume:

V = 2π ∫[0,2] x * (8 - x³) dx

Now, let's evaluate this integral:

V = ∫[0, 2] 2π(8x - x^4) dx

= 2π ∫[0, 2] (8x - x^4) dx

=2π [[tex]4x^2 - (x^5[/tex]/5)] |[0, 2]

= 2π[tex][(4(2)^2-(2^5/5)) - (4(0)^2 - (0^5/5))][/tex]

= 2π [16 - 32/5]

= 2π (80/5 - 32/5)

= 2π (48/5)

= 96π/5

Therefore, the volume of the solid generated by revolving the plane region about the x-axis is 96π/5 units cubed.

The answer explains how to find the length of a curve using the given parametric equations. It discusses the concept of arc length and provides the steps to calculate the length of the curve.

To find the length of the given curve with parametric equations x = 8 cos t + 8t sin t and y = 8 sin t - 8t cos t, we can use the concept of arc length. The arc length represents the distance along the curve between two points.

To calculate the length of the curve, we can use the formula for arc length, which is given by:

L = ∫[a,b] √((dx/dt)^2 + (dy/dt)^2) dt,

where a and b are the parameter values that define the range of the curve.

In this case, we have x = 8 cos t + 8t sin t and y = 8 sin t - 8t cos t. By differentiating these equations with respect to t, we can find dx/dt and dy/dt. Then, we substitute these values into the arc length formula and integrate over the appropriate range [a, b].

The resulting integral will provide the length of the curve. By evaluating the integral, we can obtain the numerical value of the length.

To find the volume of the solid generated by rotating the region R, bounded by the functions f(x) = x^2 and g(x) = 0 (the x-axis), around the x-axis, we can use the method of cylindrical shells.

The height of each cylindrical shell will be the difference between the functions f(x) and g(x). Thus, the height of each shell is h(x) = f(x) - g(x) = x^2 - 0 = x^2.

The radius of each shell is the x-coordinate at which it is formed. In this case, the shells are formed between x = 0 and x = 1 (the interval where the region R exists).

To calculate the volume of each shell, we use the formula for the volume of a cylindrical shell: V_shell = 2πrh(x)dx.

The total volume of the solid can be found by integrating the volumes of all the shells over the interval [0, 1]:

V = ∫[0,1] 2πrh(x)dx

= ∫[0,1] 2πx(x^2)dx

= 2π ∫[0,1] x^3 dx

= 2π [(1/4)x^4] [0,1]

= 2π (1/4)

= π/2

To rewrite the function g(x) as a sum or difference, we can split it into two terms: 4x⁸ and -3x⁶. Thus, g(x) = 4x⁸ - 3x⁶.

To find the derivative of g(x), g'(x), we apply the power rule of differentiation. For each term, we multiply the coefficient by the power of x and decrease the power by 1. Therefore, the derivative of 4x⁸ is 32x⁷, and the derivative of -3x⁶ is -18x⁵.

(a) Direct Integration:

To directly integrate the given integral, we find the antiderivative of (4ln(x^2 + 1))/x. By using integration techniques such as substitution, we obtain the result.

(b) Trapezoidal Rule:

The trapezoidal rule approximates the integral by dividing the interval [a, b] into subintervals and approximating the area under the curve using trapezoids. The more subintervals we use, the more accurate the approximation becomes. We calculate the approximation by applying the formula.

(c) Simpson's Rule:

Simpson's rule is another numerical approximation method that provides a more accurate estimate of the integral. It approximates the curve by using quadratic approximations within each subinterval. Similar to the trapezoidal rule, we divide the interval into subintervals and calculate the approximation using the formula.

By applying the respective method, we can evaluate the integral ∫(4ln(x^2 + 1))/x dx and obtain the numerical value of the integral. Each method has its own advantages and accuracy level, with Simpson's rule typically providing the most accurate approximation among the three.

The given region can be expressed as a dy-region with the following limits of integration:

0 ≤ z ≤ 6 - 2r - 2y

0 ≤ r ≤ ∞

0 ≤ y ≤ -13 - r

Let's express the region bounded by the coordinate planes and the plane 2r + 2y + 32 = 6 as a dz-region.

To do this, we need to solve the equation 2r + 2y + 32 = 6 for z. Rearranging the equation, we have:

2r + 2y = 6 - 32

2r + 2y = -26

Dividing both sides by 2, we get:

r + y = -13

Now, we can express the region as a dz-region by setting up the limits of integration for r, y, and z:

0 ≤ r ≤ -13 - y

0 ≤ y ≤ -13 - r

0 ≤ z ≤ 6 - 2r - 2y

In this case, we can choose to express the region as a dy-region. To do so, we will integrate with respect to y first, followed by r.

The limits of integration for y are given by:

0 ≤ y ≤ -13 - r

Next, we integrate with respect to r, while considering the limits of integration for r:

0 ≤ r ≤ ∞

Finally, we integrate with respect to z, while considering the limits of integration for z:

0 ≤ z ≤ 6 - 2r - 2y

Therefore, the given region can be expressed as a dy-region with the following limits of integration:

The period of a trigonometric function is the horizontal distance between two consecutive points on the graph that have the same value. For the function y = cos(θ), where θ represents an angle in radians, the period is equal to 2π.

The cosine function has a period of 2π, which means that it repeats itself every 2π units. This can be seen from the graph of the cosine function, where the value of cos(θ) at any angle θ is the same as the value of cos(θ + 2π). So, for the function y = cos(0), the period is 2π because cos(0) and cos(2π) have the same value. Similarly, for y = cos(38), the period is still 2π because cos(38) and cos(38 + 2π) are equal.

For the function y = sin(60), the sine function also has a period of 2π. Therefore, the period of y = sin(60) is 2π because sin(60) and sin(60 + 2π) have the same value. Similarly, for y = sin(100), the period is 2π because sin(100) and sin(100 + 2π) are equal.

The percentage rate of change of the function f(x) = 3500 - 2x^2 at x = 35 can be found by calculating the derivative of the function at that point and then expressing it as a percentage.

To find the rate of change of a function at a specific point, we need to calculate the derivative of the function with respect to x. For f(x) = 3500 - 2x^2, the derivative is f'(x) = -4x.

Now, we can substitute x = 35 into the derivative to find the rate of change at that point:

f'(35) = -4(35) = -140.

The rate of change at x = 35 is -140. To express this as a percentage rate of change, we can divide the rate of change by the original value of the function at x = 35 and multiply by 100:

Percentage rate of change = (-140 / f(35)) * 100.

Substituting x = 35 into the original function, we have:

f(35) = 3500 - 2(35)^2 = 3500 - 2(1225) = 3500 - 2450 = 1050.

Plugging these values into the percentage rate of change formula, we get:

Percentage rate of change = (-140 / 1050) * 100 = -13.33%.

Therefore, the percentage rate of change of f(x) at x = 35 is approximately -13.33%.

To find the volume V of the solid obtained by rotating the region bounded by the curves y = 6x^2 and y = 6x about the x-axis, we can use the method of cylindrical shells.

The inner radius of each cylindrical shell is given by r1 = 6x^2 (the distance from the x-axis to the curve y = 6x^2), and the outer radius is given by r2 = 6x (the distance from the x-axis to the curve y = 6x).

The height of each cylindrical shell is the infinitesimal change in x, denoted as Δx.

The volume of each cylindrical shell is given by the formula: dV = 2πrhΔx, where r is the average radius of the shell.

To find the volume, we integrate the volume of each cylindrical shell over the interval [0, c], where c is the x-coordinate of the intersection point of the two curves.

V = ∫[0, c] 2πrh dx = ∫[0, c] 2π(6x)(6x^2) dx = ∫[0, c] 72πx^3 dx

The area of the region enclosed by the given curves is 31/24 square units.

To find the area of the region enclosed by the curves y - x = 1 and y = 2x^2, we need to determine the intersection points between the two curves and set up a single integral to calculate the area.

First, let's find the intersection points by setting the equations equal to each other:

2x^2 = x + 1

Rearranging the equation:

2x^2 - x - 1 = 0

To solve this quadratic equation, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For this equation, a = 2, b = -1, and c = -1. Plugging in these values into the quadratic formula, we get:

x = (-(-1) ± √((-1)^2 - 4(2)(-1))) / (2(2))

x = (1 ± √(1 + 8)) / 4

x = (1 ± √9) / 4

x = (1 ± 3) / 4

This gives us two potential x-values: x = 1 and x = -1/2.

To determine which intersection points are relevant for the given region, we need to consider the corresponding y-values. Let's substitute these x-values into either equation to find the y-values:

For y - x = 1:

When x = 1, y = 1 + 1 = 2.

When x = -1/2, y = -1/2 + 1 = 1/2.

Now we have the intersection points: (1, 2) and (-1/2, 1/2).

To set up the integral for finding the area, we need to integrate the difference between the two curves over the interval [a, b], where a and b are the x-values of the intersection points.

In this case, the area can be calculated as:

Area = ∫[a, b] (2x^2 - (x + 1)) dx

Using the intersection points we found earlier, the integral becomes:

Area = ∫[-1/2, 1] (2x^2 - (x + 1)) dx

To evaluate the integral and find the area of the region enclosed by the curves, we will integrate the expression (2x^2 - (x + 1)) with respect to x over the interval [-1/2, 1].

The integral can be split into two parts:

Area = ∫[-1/2, 1] (2x^2 - (x + 1)) dx

    = ∫[-1/2, 1] (2x^2 - x - 1) dx

Let's evaluate each term separately:

∫[-1/2, 1] 2x^2 dx = [2/3 * x^3] from -1/2 to 1

                 = (2/3 * (1)^3) - (2/3 * (-1/2)^3)

                 = 2/3 - (-1/24)

                 = 17/12

∫[-1/2, 1] x dx = [1/2 * x^2] from -1/2 to 1

               = (1/2 * (1)^2) - (1/2 * (-1/2)^2)

               = 1/2 - 1/8

               = 3/8

∫[-1/2, 1] -1 dx = [-x] from -1/2 to 1

                = -(1) - (-(-1/2))

                = -1 + 1/2

                = -1/2

Now, let's calculate the area by subtracting the integrals:

Area = (17/12) - (3/8) - (-1/2)

    = 17/12 - 3/8 + 1/2

    = (34 - 9 + 6) / 24

a) To find the Cartesian coordinates for the polar coordinate (3, -77), we can use the formulas:

x = r * cos(θ)

y = r * sin(θ)

In this case, r = 3 and θ = -77 degrees.

x = 3 * cos(-77°)

y = 3 * sin(-77°)

Using a calculator, we can find the approximate values of cos(-77°) and sin(-77°). Let's denote them as cos(-77) and sin(-77) respectively.

x ≈ 3 * cos(-77)

y ≈ 3 * sin(-77)

Therefore, the Cartesian coordinates for the polar coordinate (3, -77) are approximately (3 * cos(-77), 3 * sin(-77)).

b) To find the polar coordinates for the Cartesian coordinate (-3, -1), we can use the formulas:

r = sqrt(x^2 + y^2)

θ = atan2(y, x)

In this case, x = -3 and y = -1.

r = sqrt((-3)^2 + (-1)^2)

θ = atan2(-1, -3)

Using a calculator, we can find the values of sqrt((-3)^2 + (-1)^2) and atan2(-1, -3). Let's denote them as sqrt(10) and θ respectively.

r = sqrt(10)

θ = atan2(-1, -3)

Therefore, the polar coordinates for the Cartesian coordinate (-3, -1) are (sqrt(10), θ).

To find the parametric equations of the line passing through point A(4, -5, -2) and normal to the plane -2x - y + 32 = -8, we first need to determine the direction vector of the line. The coefficients of x, y, and z in the plane's equation give us the normal vector, which is n = [-2, -1, 0].

For the symmetric equations, we can express the coordinates in terms of their differences from the corresponding coordinates of the point A. This gives us (x - 4)/5 = (y + 5)/(-2) = (z + 2)/0. Note that the denominator of z is 0, indicating that z does not change and remains at -2 throughout the line.

The line integral of vector field ⃗F→ around a circle of radius a, centered at the origin, can be evaluated using Green's theorem. The result is 2πa^3e, where e is Euler's number.

In the given vector field ⃗F→, we have two components: Fx = 3x^2y + y^3 + 3ex and Fy = 4y^2 + 75x. To evaluate the line integral around the circle, we first express the vector field in terms of its components: ⃗F→ = Fx i→ + Fy j→.

Using Green's theorem, the line integral of ⃗F→ around a closed curve C is equal to the double integral of the curl of ⃗F→ over the region enclosed by C. In this case, the region enclosed by the circle of radius a is a disk.

The curl of ⃗F→ is given by ∇×⃗F→ = (∂Fy/∂x - ∂Fx/∂y)k→. Calculating the partial derivatives and simplifying, we find that ∇×⃗F→ = (3e - 75)k→.

Now, we can evaluate the line integral by calculating the double integral of ∇×⃗F→ over the disk. Since the curl is a constant, the double integral simplifies to the product of the curl and the area of the disk. The area of the disk is given by πa^2, so the line integral becomes (∇×⃗F→)πa^2 = (3e - 75)πa^2k→.

Finally, we extract the component of the result along the z-axis, which is the k→ component, and multiply it by 2πa, the circumference of the circle. The z-component of (∇×⃗F→)πa^2 is (3e - 75)πa^3. Thus, the line integral of ⃗F→ around the circle of radius a is equal to 2πa^3e.

In summary, the line integral of the given vector field ⃗F→ around a circle of radius a, centered at the origin, is equal to 2πa^3e, where e is Euler's number. This result is obtained by applying Green's theorem and evaluating the double integral of the curl of ⃗F→ over the disk enclosed by the circle.

The projection of the region D, which is enclosed by two paraboloids, onto the xy-plane. The correct answer is not provided within the given options.

To find the projection of the region D onto the xy-plane, we need to eliminate the z-coordinate and focus only on the x and y coordinates. The projection is obtained by considering the intersection of the two paraboloids when z = 0. This occurs when 3x² + y² = 16 - x², which simplifies to 4x² + y² = 16.

The equation 4x² + y² = 16 represents an ellipse in the xy-plane. Therefore, the correct answer should be the option that represents an ellipse. However, since none of the given options match this, the correct answer is not provided.

To visualize the projection, you can plot the equation 4x² + y² = 16 on the xy-plane. The resulting shape will be an ellipse centered at the origin, with major axis along the x-axis and minor axis along the y-axis.

To answer both parts of the question, we need more information about the function and point of center to be able to compute the Taylor series in detail.

To find the Taylor series of a given function centered at a particular point, we use the formula:

f(x) = f(a) + f'(a)(x-a) + (1/2!)f''(a)(x-a)^2 + (1/3!)f'''(a)(x-a)^3 + ...

where f'(x), f''(x), f'''(x), etc. represent the first, second, and third derivatives of the function f(x), respectively.

In this case, we are given the function = x _je_rsoɔSÞI i = x and we need to find its Taylor series centered at some point. However, we are not given the specific point, so we cannot compute the Taylor series without knowing the point of center.

As for the second part of the question, we are asked to compute the Taylor series of each function. However, we are not given any specific functions to work with, so we cannot provide an answer without additional information.

Based on the given cost and revenue functions, we can conclude that:

a) The profit function can be found by subtracting the cost function from the revenue function:

P(x) = R(x) - C(x)

P(x) = (2000x - 60) - (4000 + 500x)

P(x) = 1500x - 3940

b) To find the break-even quantity, we need to set the profit function equal to zero:

0 = 1500x - 3940

1500x = 3940

x = 2.63

So the break-even quantity is 2.63 thousand units, or 2630 units.

To find the larger break-even quantity, we need to compare the break-even quantities for the revenue and cost functions.

For the revenue function:

0 = 2000x - 60

2000x = 60

x = 33.3

So the break-even quantity for the revenue function is 33.3 thousand units or 3330 units, meaning the company needs to sell at least 3330 unit to cover its variable costs.

Since the break-even quantity for the cost function is greater than 0, the larger break-even quantity is 33.3 thousand units, as calculated in part b).

a. The profit function is P(x) = 940x - 4000.

b. The larger break-even quantity is  4.26 thousand units.

a) The profit function, we subtract the cost function from the revenue function:

Profit function P(x) = R(x) - C(x)

Cost function C(x) = 4000 + 500x

Revenue function R(x) = 2000x - 60x

Substituting the values into the profit function:

P(x) = (2000x - 60x) - (4000 + 500x)

P(x) = 2000x - 60x - 4000 - 500x

P(x) = 1440x - 4000 - 500x

P(x) = 940x - 4000

So, the profit function is P(x) = 940x - 4000.

b) The break-even quantity, we need to set the profit function equal to zero and solve for x:

Profit function P(x) = 940x - 4000

Setting P(x) = 0:

0 = 940x - 4000

Adding 4000 to both sides:

940x = 4000

Dividing both sides by 940:

x = 4000 / 940

x ≈ 4.26

The break-even quantity is approximately 4.26 thousand units.

The value derivative of the function of f'(6) is  403.42879 and f'(7) is 1096.633.

To find the derivative of the function f(x) = ex + 3, we can use the basic rules of differentiation. Let's calculate the derivatives step by step.

(a) Find f'(6):

To find the derivative at a specific point, we can use the formula:

f'(x) = d/dx [ex + 3]

The derivative of ex is ex, and the derivative of a constant (3) is 0. Therefore, the derivative of f(x) = ex + 3 is:

f'(x) = ex

Now, we can find f'(6) by plugging in x = 6:

f'(6) = e^6 ≈ 403.42879 (rounded to 6 decimal places)

So, f'(6) ≈ 403.42879.

(b) Find f'(7):

Using the same derivative formula, we have:

f'(x) = d/dx [ex + 3]

f'(x) = ex

Now, we can find f'(7) by plugging in x = 7:

f'(7) = e^7 ≈ 1096.63316 (rounded to 6 decimal places)

So, f'(7) ≈ 1096.633.

The value of c that satisfies the condition is c = 1/4.

To find the value of c, we need to determine the rate of change of f(x) at x = c and at x = 1 and set up an equation based on the given condition.

The given function is f(x) = x^(1/2).

To find the rate of change of f(x) at x = c, we take the derivative of the function with respect to x:

f'(x) = (1/2)x^(-1/2) = 1/(2√x)

Now, let's calculate the rate of change at x = c:

f'(c) = 1/(2√c)

Similarly, for x = 1:

f'(1) = 1/(2√1) = 1/2

According to the given condition, the rate of change of f at x = c is twice its rate of change at x = 1. Mathematically, this can be expressed as:

2 * f'(1) = f'(c)

2 * (1/2) = 1/(2√c)

1 = 1/(2√c)

To solve this equation, we can square both sides:

1 = 1/4c

4c = 1

c = 1/4

Therefore, the value of c that satisfies the condition is c = 1/4.

The series ∑(an) = 7n^3 – 6n^2 + 11 / (8 + 4n^4) converges.

To determine whether the series ∑(an) = 7n^3 – 6n^2 + 11 / (8 + 4n^4) converges or diverges, we will use the limit comparison test.

First, we need to get a series bn with terms of the form bn = f(n) that is easier to evaluate. Let's choose bn = 1/n^3.

Now, we will calculate the limit of the ratio an/bn as n approaches infinity:

lim(n->∞) (an/bn) = lim(n->∞) [(7n^3 – 6n^2 + 11) / (8 + 4n^4)] / (1/n^3)

To simplify the expression, we can divide the numerator and denominator by n^3:

lim(n->∞) [(7n^3 – 6n^2 + 11) / (8 + 4n^4)] / (1/n^3) = lim(n->∞) [(7 - 6/n + 11/n^3) / (8/n^3 + 4)]

Now, we can take the limit as n approaches infinity:

lim(n->∞) [(7 - 6/n + 11/n^3) / (8/n^3 + 4)] = 7/4

Since the limit of the ratio an/bn is a finite positive number (7/4), and the series bn = 1/n^3 converges (as it is a p-series with p > 1), we can conclude that the series ∑(an) also converges by the limit comparison test.

Therefore, the series ∑(an) = 7n^3 – 6n^2 + 11 / (8 + 4n^4) converges.

The interval of convergence for the power series (z - 10)ⁿ is (-∞, ∞). The series converges for all values of a.

To determine the interval of convergence for the power series (z - 10)ⁿ, 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, then the series converges.

Taking the absolute value of the terms in the power series, we have |z - 10|ⁿ. Applying the ratio test, we consider the limit as n approaches infinity of |(z - 10)ⁿ⁺¹ / (z - 10)ⁿ|.

Simplifying the expression, we get |z - 10|. The limit of |z - 10| as z approaches any real number is always 0. Therefore, the ratio test is always satisfied, and the series converges for all values of a.

In interval notation, therefore the interval of convergence is (-∞, ∞), indicating that the series converges for any real value of a.
