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)

G (3,3) will become G'(14,9)

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.

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 estimated number of students on the A honor roll who are 8th graders is 126.

Algebra is a branch of mathematics that deals with symbols and the rules for manipulating these symbols. It involves using letters and other symbols to represent numbers and quantities in equations and formulas.

The main goal of algebra is to find the value of an unknown quantity, called a variable, by using known quantities and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. Algebraic expressions can be solved using various techniques, including simplification, factoring, and solving equations.

The total number of students on the A honor roll is given by adding the number of students in each grade:

Total = 15 (6th grade) + 11 (7th grade) + 14 (8th grade) = 40

To find the proportion of students who are in 8th grade, we can divide the number of 8th graders by the total number of students:

Proportion of 8th graders = 14/40 = 0.35

To estimate the number of students on the A honor roll who are 8th graders, we can multiply the proportion of 8th graders by the total number of students on the A honor roll:

Estimated number of 8th graders = 0.35 x 360 = 126

Therefore, the estimated number of students on the A honor roll who are 8th graders is 126.

Consider the equation |x-4| = 5. This equation has two solutions since the distance of x from 4 on the number line can be 5 units in either direction, giving x = 9 or x = -1.

What is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas.

An absolute value equation is of the form |x| = a, where "a" is a positive number. The absolute value of a number is always non-negative, so the equation |x| = a has two possible solutions, x = a and x = -a.

However, there are three possible cases for how many solutions an absolute value equation could have:

One solution: This occurs when a=0. The only solution is x=0 because |0|=0.

Two solutions: This occurs when a > 0. The two possible solutions are x = a and x = -a, since |a| = a and |-a| = a. For example, the equation |x-3| = 2 has two solutions: x-3 = 2 or x-3 = -2, which gives x = 5 or x = 1.

No solutions: This occurs when a < 0. Since the absolute value of a number is always non-negative, an absolute value equation with a negative number on the right-hand side has no solutions. For example, the equation |x-3| = -2 has no solutions since -2 is negative.

The difference in the number of solutions is due to the nature of absolute values. The absolute value of a number represents the distance of the number from zero on the number line, so an absolute value equation can have two solutions when the distance is equal to a positive number, one solution when the distance is equal to zero, and no solution when the distance is less than zero.

For example, consider the equation |x-4| = 5. This equation has two solutions since the distance of x from 4 on the number line can be 5 units in either direction, giving x = 9 or x = -1.

Answer: Absolute value equations are important in situations where values cannot be negative, like measuring distance. For example, if you forget which floor your friend lives on and he tells you he's on the fourth floor, and you say you're two floors away, you could be on either the second or sixth floor. Absolute value inequalities are important in determining margins of error or tolerance, especially in manufacturing.

Step-by-step explanation:

When solving an absolute value equation, three possible scenarios could occur. The first scenario is when the absolute value expression equals a positive number. In this case, there will be two solutions, one positive and one negative. The second scenario is when the absolute value expression equals zero. In this case, there will be only one solution, which is zero. The third and final scenario is when the absolute value expression equals a negative number. In this case, there are no solutions, as the absolute value of any number is always non-negative.

The reason there are differences in the number of solutions for each case is due to the nature of absolute value. Absolute value always returns a non-negative value, regardless of the sign of the number inside the absolute value expression. Therefore, when the absolute value expression is positive, there are two possible solutions, one positive and one negative. When the expression equals zero, there is only one solution, which is zero. And when the expression is negative, there are no solutions, as there cannot be a negative absolute value.

[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 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.
