Answer:

[tex]625 \: {in}^{3} [/tex]

Step-by-step explanation:

This figure is formed from a cube and a rectangular prism

First, we can find the volume of the cube:

(l (side length) = 5 in)

[tex]v(cube) = {l}^{3 } = {5}^{3} = 125 \: {in}^{3} [/tex]

Now, let's find the volume of the rectangular prism:

(h = 5 in; a (base area) = 20 × 5 = 100 in^2)

[tex]v(prism) = a(base) \times h[/tex]

[tex]v(prism) = 100 \times 5 = 500 \: {in}^{3} [/tex]

In order to find the total volume of this figure, we have to add these two volumes together:

[tex]v(total) = v(cube) + v(prism)[/tex]

[tex]v(total) = 125 + 500 = 625 \: {in}^{3} [/tex]

The ratio of the height of the smaller prism to the height of the larger prism is 1:sqrt(27).

what is prism?

A prism is a geometric solid that has two parallel and congruent polygonal bases, and the sides connecting the bases are parallelograms. These parallelograms are typically rectangles, but they can also be squares or rhombuses. A prism can be named based on the shape of its base, such as a rectangular prism, triangular prism, hexagonal prism, etc.

Since the prisms are similar, their corresponding sides are proportional. In particular, the ratio of the heights of the prisms is the same as the ratio of their volumes.

Let the height of the smaller prism be h1 and the height of the larger prism be h2. Let the volume of the smaller prism be V1 = 15 cm^3 and the volume of the larger prism be V2 = 405 cm^3. Then:

V1/V2 = (h1^2 * 5) / (h2^2 * 5)

V1/V2 = h1^2 / h2^2

sqrt(V1/V2) = h1 / h2

Substituting the given values, we get:

sqrt(15/405) = h1 / h2

sqrt(1/27) = h1 / h2

1/sqrt(27) = h1 / h2

Therefore, the ratio of the height of the smaller prism to the height of the larger prism is 1:sqrt(27), or approximately 1:5.2.

we have shown that [tex]$(a^m)^n = a^{mn}$[/tex] for all [tex]$a \in G$[/tex] and [tex]$m, n \in \mathbb{Z}$[/tex].

To prove that in a group G, [tex]$(a^m)^n = a^{mn}$[/tex] for all [tex]$a \in G$[/tex] and [tex]$m, n \in \mathbb{Z}$[/tex], we need to show that both sides of the equation are equal.

We start by simplifying the left-hand side:

[tex]$(a^m)^n = a^{mn}$[/tex]

This is because raising a to the power of m and then to the power of n is the same as raising a to the power of mn. This property is known as the associative property of exponents.

Next, we need to show that the right-hand side of the equation is also equal to [tex]$a^{mn}$[/tex]:

[tex]$a^{mn} = a^{nm}$[/tex]

This is because multiplication is commutative in [tex]$\mathbb{Z}$[/tex], which means that [tex]$mn = nm$[/tex]

The statement that is NOT true is: "The y-intercept of the line of best fit means that it cost $9,994 to build the house."

Hi! Based on the given information and without a visual of the graph, I will provide a general answer using the terms provided. Please note that an accurate response may require additional information or context.

The slope of the line of best fit indicates the rate of change in the value of the house over time, and a positive slope signifies that the value has increased. However, the y-intercept of the line of best fit does not necessarily mean that it cost $9,994 to build the house.

The y-intercept represents the estimated value of the house when the independent variable (usually time) is zero, but it does not account for factors like construction costs, inflation, or changes in the real estate market.

The margin of safety in dollars is $113100

The margin of safety is the value of sales or sales in units that are in excess of the break-even sales or units. The break-even point is where the firm is neither making a profit nor a loss and its total revenue is equal to its total expenses.

The margin of safety can be calculated by deducting the break-even sales value from the budgeted/actual sales value.

The margin of safety in dollars = budgeted/actual sales value - break-even sales value

Margin of safety in dollars = (87 * 13000) - (87 * 11700) = $113100

The graph of the original triangle and the after the dilation are shown below:

Triangle dilation graph 8.

Dilation refers to the process of expanding or stretching an object or a space in one or more directions. In mathematics, dilation is a geometric transformation that changes the size of an object or a figure by either enlarging or reducing its dimensions, while preserving its shape and orientation.

In the context of image processing and computer vision, dilation is an operation that is commonly used to enhance and extract features from images. It involves convolving an image with a small structuring element or kernel, which slides over the image and replaces each pixel with the maximum value within the kernel.

For a dilation with a scale factor of 0.5 and centered at the origin, each coordinate of the triangle will be multiplied by 0.5. Thus:

J(8,0) will become J'(4,0)

L(-2,0) will become L'(-1,0)

K(4,4) will become K'(2,2)

The graph of the original triangle and the image after the dilation are shown below:

Triangle dilation graph 6

For a dilation with a scale factor of 2 and centered at the point (8,3), each coordinate of the triangle will be multiplied by 2 and then translated by the vector (8,3). Thus:

A (9,8) will become A'(26,14)

C (0,2) will become C'(8,7)

Answer:

A + B + C = 68

Step-by-step explanation:

A : B = 1 : 2

B : C = 3 : 4

Find the LCM of 2 and 3. LCM = 6

Multiply A : B by 3 and B : C by 2      

[tex]\dfrac{A}{B}=\dfrac{1}{2}=\dfrac{1*3}{2*3}=\dfrac{3}{6}\\\\\\\dfrac{B}{C }=\dfrac{3}{4}=\dfrac{3*2}{4*2}=\dfrac{6}{8}[/tex]

A : B = 3 : 6    &   B : C = 6 :8

A : B : C = 3 : 6 : 8

A = 3x

B = 6x

C = 8x

It is given that C is 32.

         8x = 32

Divide both sides by 8

          x = 32÷ 8

          x = 4

A = 3*4 = 12

B = 6 * 4 = 24

Sum of three numbers = 12 + 24  + 32

                                      = 68

There is no x-coordinate where the graph of the function [tex]f(x) = e^{-x^{2}}[/tex] has a slope of 0. However, the best answer would be (A) 0.

Given: D = 8 1/2 in.

We know that the diameter of a circle is twice the radius. Therefore, we can find the radius by dividing the diameter by 2:

radius (r) = D/2 = 8 1/2 / 2 = 4 1/4 in.

To find the circumference (C) of the circle, we can use the formula:

C = 2πr

where π (pi) is a constant approximately equal to 3.14.

Substituting the value of r, we get:

C = 2π(4 1/4) = 2π(17/4) = 8.5π

Therefore, the radius is 4 1/4 in. and the circumference is 8.5π in.

The axis of symmetry for f(x) is x = 1 and h(x) is x=3.

The axis of symmetry is an imaginary straight line that divides a shape into two identical parts, thereby creating one part as the mirror image of the other part. When folded along the axis of the symmetry, the two parts get superimposed. The straight line is called the line of symmetry/the mirror line. This line can be vertical, horizontal, or slanting.

Assuming that f(x) and h(x) are quadratic functions, here's how to find the axis of symmetry for each function:

f(x) = 2x² - 4x + 1

To find the axis of symmetry for f(x), we first identify the coefficients a, b, and c:

a = 2, b = -4, c = 1

Then, we use the formula:

x = -b / (2a) = -(-4) / (2 * 2) = 1

Therefore, the axis of symmetry for f(x) is x = 1. This means that the graph of f(x) is symmetric with respect to the vertical line x = 1.

h(x) = -x² + 6x - 5

To find the axis of symmetry for h(x), we first identify the coefficients a, b, and c:

a = -1, b = 6, c = -5

Then, we use the formula:

x = -b / (2a) = -6 / (2 * -1) = 3

Therefore, the axis of symmetry for h(x) is x = 3. This means that the graph of h(x) is symmetric with respect to the vertical line x = 3.

Karen and Wayne will need to make monthly payments of $66.39 for 3 years to pay off the loan for their new refrigerator for a given sales tax.

The add-on interest loan formula can be used to determine the monthly payment:

(Loan amount + Interest) / the number of payments equals a payment.

We must first determine the refrigerator's total cost, including sales tax:

Final price is $1,598 plus 5% of $1,598.

$1,677.90 is the total price.

Secondly, we must determine the loan's interest rate:

Interest is calculated as Loan Amount * Addition Rate. Ages in years

Interest equals $702.25 when $1,677.90 multiplied by 0.14 by three.

When interest is included, the total loan amount is:

Loan amount = Purchase price plus interest

Total of the loan: $1,677.90 plus $702.25

Amount borrowed: $2,380.15

In the end, we can figure out the monthly payment:

Payment: ($2,380.15) divided by (3 years * 12 months/year) =
