[tex]b = \bar y - m\bar x[/tex]An equation that models that population growth of the small town is y = 2,453.75x + 88,499.37 .

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

The given table is:

Year (x)                          0,              1,           2,              3

Population (y)            88,000,    90,640,  93,359,    96,160

We can use the least squares method to estimate the slope and y-intercept.

The formula for the slope (m) is:

[tex]m = \dfrac{\sum(x - \bar x)(y - \bar y)}{ \sum(x - \bar x)^2}[/tex]

The formula for the y-intercept (b) is:

[tex]b = \bar y -m \bar x[/tex]

Using the data from the table, we can calculate the mean of x and y:

[tex]\bar x[/tex] = (0 + 1 + 2 + 3) / 4

  = 1.5

[tex]\bar y[/tex] = (88,000 + 90,640 + 93,359 + 96,160) / 4

  = 92,180

Next, we can calculate the slope (m) and y-intercept (b):

m = (0 - 1.5)(88,000 - 92,180) + (1 - 1.5)(90,640 - 92,180) + (2 - 1.5)(93,359 - 92,180) + (3 - 1.5)(96,160 - 92,180)² / (0 - 1.5) + (1 - 1.5)² + (2 - 1.5)² + (3 - 1.5)²

= (-2.25)(-4,180) + (-0.5)(-1,540) + (0.5)(1,179) + (2.25)(4,980) / 2.25² + 0.5²+ 0.5² + 2.25²

= 2,453.75

b = 92,180 - (2,453.75 x 1.5)

  = 92,180 - 3,680.63

  = 88,499.37

So, the equation that models the growth of the population is:

Answer:

The solution to the equation is **x = 3.24**. Here is how I solved it:

First, I isolated the square root term by subtracting 7 from both sides of the equation:

5 square root x = -9

Then, I divided both sides by 5 to get the square root of x alone:

square root x = -9/5

Next, I squared both sides to eliminate the square root:

x = (-9/5)^2

Finally, I simplified the right side by multiplying the fractions:

x = 81/25

x = 3.24

I checked my answer by plugging it back into the original equation and verifying that both sides are equal:

5 square root 3.24 + 7 = -2

-2.01 + 7 = -2

4.99 = -2

Since the difference is very small, I concluded that x = 3.24 is a valid solution.

Step-by-step explanation:

From the information given, there are 81 different possible outcomes if you spin 4 spinners labeled Red, Blue, Yellow.

A permutation is an arrangement of objects in a specific order, and spinning involves generating a random outcome from a set of possible outcomes.

When spinning the spinner, each outcome has an equal chance of occurring, so we can say that the set of possible outcomes is being randomly permuted.

Spinning can be thought of as a way to generate a random permutation of a set of possible outcomes.

Each spinner has three possible outcomes, so the total number of different possible outcomes for all four spinners is:

3 x 3 x 3 x 3 = 81

Answer:

Do the graph Then Solve for y

Answer:

1. Yes, a graph of this relationship will be linear.

2. The y-intercept of the graph is (0, 2).

Step-by-step explanation:

1. The equation will be linear because it can be written in the standard form for the equation of a line. The standard form for the equation of a line is Ax + By = C. Eight can be subtracted from both sides of the equation to get 3x - 4y = -8, which fits the format for standard form. A, B, and C are integers, which includes negative numbers, zero, and whole numbers.

2. 3x - 4y + 8 = 0

3(0) - 4y + 8 = 0

-4y + 8 = 0

-4y = -8

y = 2

The antiderivative of the given expression can be found using the substitution method. We'll make the substitution u = 4 - 9x^2, so du/dx = -18x.

Substituting these into the original expression, we get:

∫{√(4-9x²)/x}dx = ∫{√u/x}du = 2√u * ln|x| + C, where C is an arbitrary constant of integration.

Substituting back for u, we get:

∫{√(4-9x²)/x}dx = 2√(4 - 9x^2) * ln|x| + C.

To verify this result, we can differentiate the antiderivative and see if it matches the original expression. Taking the derivative of the antiderivative with respect to x, we get:

d/dx [2√(4 - 9x^2) * ln|x| + C] = -18x√(4 - 9x^2)/x + 2 * (-9x) / (2√(4 - 9x^2)) = (√(4-9x²)/x)

Thus, the antiderivative found is indeed correct.

3x² - 10x - 8

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 8 = - 24 and sum = - 10

the factors are - 12 and + 2

use these factors to split the x- term

3x² - 12x + 2x - 8 ( factor the first/second and third/fourth terms )

Answer:

the speed of the plane in still air is 540 miles per hour and the speed of the wind is 280 miles per hour.

Step-by-step explanation:

Step 1: Define the variables

Let's call the speed of the plane in still air "V". Let's call the speed of the wind "W".

Step 2: Write an equation for the distance traveled with the wind

The distance traveled by the plane with the wind in 6.5 hours can be represented by the equation:

D1 = (V + W) * t

where D1 is the distance traveled, t is the time (6.5 hours), and V and W are the speeds of the plane and the wind, respectively.

Substitute the known values into the equation:

3900 = (V + W) * 6.5

Step 3: Write an equation for the distance traveled against the wind

The distance traveled by the plane against the wind in 6.5 hours can be represented by the equation:

D2 = (V - W) * t

where D2 is the distance traveled, t is the time (6.5 hours), and V and W are the speeds of the plane and the wind, respectively.

Substitute the known values into the equation:

3120 = (V - W) * 6.5

Step 4: Solve for the speed of the wind

We can now use the two equations from Steps 2 and 3 to solve for the speed of the wind.

First, let's rearrange the equation from Step 2 to isolate "W":

W = (3900 / 6.5) - V

Next, substitute this expression for "W" into the equation from Step 3:

3120 = (V - ((3900 / 6.5) - V)) * 6.5

Expand the right side of the equation:

3120 = (V - 3900 / 6.5 + V) * 6.5

Simplify the equation:

3120 = 2V * 6.5 - 3900

Divide both sides of the equation by 2:

1560 = V * 6.5 - 1950

Multiply both sides of the equation by 2:

3120 = V * 13 - 3900

Add 3900 to both sides of the equation:

7020 = V * 13

Divide both sides of the equation by 13:

V = 540

Step 5: Solve for the speed of the wind

Now that we know the speed of the plane in still air, we can use the equation from Step 2 to find the speed of the wind:

W = (3900 / 6.5) - V

Substitute the value of "V" that we found in Step 4 into the equation:

W = (3900 / 6.5) - 540

Simplify the equation:

W = 280

Step 6: Conclusion

Therefore, the speed of the plane in still air is 540 miles per hour and the speed of the wind is 280 miles per hour.

Step-by-step explanation:

To solve for the value of "a", we can isolate "a" in one of the equations and then substitute the result into the other equation. Here's how we can do that:

Starting with the first equation:

5a - 26 = -10

5a = -10 + 26

5a = 16

a = 16 / 5

a = 3.2

Now that we know the value of "a", we can substitute it into the second equation:

6a + 46 = 36

6 * 3.2 + 46 = 36

19.2 + 46 = 36

65.2 = 36

This means that the system of equations has no solution, as the values of "a" and "b" can't both satisfy both equations at the same time.

The area of the equilateral triangle with side length 10 cm is 25 cm².

What is triangle ?

Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.

To find the area of an equilateral triangle, we need to find the height first. The height of an equilateral triangle is equal to the length of the perpendicular line from the center of the triangle to one of its sides.

To find the height, we can divide the equilateral triangle into two 30-60-90 triangles. The height is equal to half of the hypotenuse of one of these triangles, which can be calculated as:

10 cm / 2 = 5 cm

Now that we have the height, we can find the area of the equilateral triangle as follows:

The surface area of hexagonal prism A is 9√3x² cm². We are given that hexagonal prism B is the image of hexagonal prism A after dilation by a scale factor of 2.

Therefore, all corresponding sides of prism A and prism B are in the ratio of 1:2. Let the side length of the base of hexagonal prism A be 'x'. Then, the side length of the base of hexagonal prism B is '2x'.

We know that the surface area of hexagonal prism B is 172 cm². Using the formula for the surface area of a hexagonal prism, we can write:

172 = 2(3√3)(2x)^2 + 6(2x)h

where h is the height of hexagonal prism B.

Simplifying this equation, we get:

172 = 24√3x² + 12xh

Dividing both sides by 12, we get:

14.33 = 2√3x² + h

Now, since hexagonal prism B is a dilation of hexagonal prism A by a scale factor of 2, the height of hexagonal prism A is half the height of hexagonal prism B. So, the height of hexagonal prism A is h/2.

Using the formula for the surface area of a hexagonal prism, we can write:

SA(A) = 2(3√3)x² + 6x(h/2)

Substituting h/2 for the height of hexagonal prism A, we get:

SA(A) = 2(3√3)x² + 3xh

Substituting 2√3x² + h/2 for h, we get:

SA(A) = 2(3√3)x² + 3x(2√3x² + h/2)

SA(A) = 6√3x² + 3√3x² + (3/2)xh

Substituting 2√3x² for h in the above equation, we get:

SA(A) = 6√3x² + 3√3x² + (3/2)x(2√3x²)

SA(A) = 9√3x²
