Step-by-step explanation:

The correct answer is option b.The approximate value of pool in that area is $20.000c.

A value that is similar to another value but not exactly equal to it is referred to as an approximation number. When the outcomes of the numerical calculations are unknown, the approximation is applied. They are typically used when greater place value decimal numbers emerge as a result.

Approximate value of a pool in the area = Value of home with a swimming pool in the area - Value of home without a swimming pool in the same area.

Value of home with a swimming pool in the area = $250,000

Value of home without a swimming pool in the same area = $230,000.

The approximate value of pool in the area = 250000 - 230000 = 20000.

Hence, the correct answer is option b. The approximate value of pool in that area is $20.000c.

This program implements a user interface that can convert between the units centimeters (cm), meters (m), and inches (in) using the conversion formulas outlined.

#include <iostream>

using namespace std;

int main()

{

// Declare variables

double value;

char fromUnit;

char toUnit;

// Get input

cout << "Enter a value and the units you wish to convert from and to (cm, m, in): ";

cin >> value >> fromUnit >> toUnit;

// Convert the value

if (fromUnit == 'm' && toUnit == 'cm') {

 value *= 100;

} else if (fromUnit == 'cm' && toUnit == 'm') {

 value /= 100;

} else if (fromUnit == 'in' && toUnit == 'm') {

 value /= 100 * 2.54;

} else if (fromUnit == 'm' && toUnit == 'in') {

 value *= 100 * 2.54;

}

// Output the result

cout << "Result: " << value << toUnit << endl;

return 0;

}

The formula used in this program is the conversion between the units centimeters (cm), meters (m), and inches (in). The conversion formula used is as follows:

1 meter (m) = 100 centimeters (cm)

1 inch (in) = 2.54 centimeters (cm)

Therefore, if we are converting from centimeters (cm) to meters (m), the conversion formula is to divide the value by 100. If we are converting from meters (m) to centimeters (cm), the conversion formula is to multiply the value by 100. For the conversion from inches (in) to meters (m), the conversion formula is to divide the value by 100 and multiply it by 2.54. For the conversion from meters (m) to inches (in), the conversion formula is to multiply the value by 100 and divide it by 2.54.

For example, if we want to convert 5 meters (m) to centimeters (cm), we use the formula 5 * 100 = 500 centimeters (cm).

This program implements a user interface that can convert between the units centimeters (cm), meters (m), and inches (in) using the conversion formulas outlined above.

Answer: 17%

Step-by-step explanation:

So, the formula to get the area of a circle is [tex]\pi r^{2}[/tex].

USA: [tex]4.2^{2} \pi[/tex] = 55.42cm

India: [tex]8.7^2\pi[/tex] = 237.79cm

From this, we can divide India by USA:

237.79 / 55.42 = 4.291

Then, with that we can multiply our 4% by 4.291:

4 * 4.291 = 17.16400

Rounded to the nearest percent is 17%

By using the midpoint rule, the value of n to approximate the integral is 9.24.

The integral of a function is a measure of the total area under the curve of the function over a given interval. The Midpoint Rule is a method used to approximate the value of an integral by dividing the interval into smaller subintervals, finding the midpoint of each subinterval, and using the height of the function at the midpoint to estimate the area of the subinterval.

In this specific problem, we are asked to approximate the integral of the function f(x) = sin root x from x = 0 to x = 48, using the Midpoint Rule with n = 4 subintervals. To do this, we divide the interval [0,48] into 4 equal subintervals of width

=> (48-0)/4 = 12.

The midpoint of each subinterval is calculated as follows:

1st subinterval: (0 + 12)/2 = 6

2nd subinterval: (12 + 24)/2 = 18

3rd subinterval: (24 + 36)/2 = 30

4th subinterval: (36 + 48)/2 = 42

Next, we find the height of the function f(x) = sin root x at each of these midpoints.

1st subinterval: sin root 6 = 0.77

2nd subinterval: sin root 18 = 0.97

3rd subinterval: sin root 30 = 0.87

4th subinterval: sin root 42 = 0.71

Finally, we multiply each height by the width of the subinterval to find the estimated area of each subinterval, and add up these areas to obtain the final estimate of the integral:

(0.77 * 12) + (0.97 * 12) + (0.87 * 12) + (0.71 * 12) = 9.24

So, our final estimate of the integral of f(x) = sin root x from x = 0 to x = 48 using the Midpoint Rule with n = 4 is 9.24. Rounding to 4 decimal places, our answer is 9.2400.

Step-by-step explanation:

The Bernoulli equation for this particular differential equation is [tex]dy/dx = 6x(y-1)[/tex]  the final solution is [tex]y = x^3 + 1[/tex].

The Bernoulli equation for this particular differential equation is [tex]dy/dx = 6x(y-1)[/tex]. To solve the equation, we first use the substitution u = y – 1. This substitution simplifies the equation to [tex]dy/dx = 6xu[/tex], which is a first-order linear equation with constant coefficients. Now we can use the method for solving Bernoulli equations to find the solution.

We first find the integrating factor, which is [tex]I(x) = exp(∫6xdx)= exp(3x^2)[/tex]. Then we multiply both sides of the equation by I(x) to get [tex]I(x)dy/dx = 6xI(x)u[/tex]. We can now integrate both sides with respect to x and get the general solution of [tex]y = u + 1 = (1/I(x))∫6xI(x)dx + 1[/tex]. After calculating the integral, the final solution is [tex]y = x^3 + 1[/tex].

Given:

The initial population of the town is 1652 people.

And the town's population is tripling every 10 years.

Let y₀ be the initial population, r be the growth rate and t be the time.

y = 1652(e[tex])^{rt}[/tex]

In 10 years,
