Therefore, angles ZACB and ZAXB are congruent, and since they are complementary to angles ZAO and ZBO, respectively, they must be supplementary.

The Circumscribed Angle Theorem states that an angle formed by two intersecting chords in a circle is half the sum of the measures of the intercepted arcs. More formally, if two chords of a circle intersect at point P, then the measure of the angle formed by the chords (let's call it angle ABC) is equal to half the sum of the measures of the arcs intercepted by the angle.

Here,

To prove that ZAXB and ZACB are supplementary, we need to show that the sum of their measures is 180 degrees. Here's the proof:

Given: ZAXB is a circumscribed angle of circle C.

To Prove: ZAXB and ZACB are supplementary.

Proof:

Draw circle C with center O and circumscribed angle ZAXB.

Draw radii OA, OB, and OC to the points of intersection A, B, and C.

Since XA and XB are tangent to circle C at points A and B, respectively, we know that angles OAX and OBX are right angles.

Therefore, angles ZAO and ZBO are complementary to angles ZAC and ZBC, respectively.

By the Inscribed Angle Theorem, we know that angles ZAO and ZBO are congruent to angle ZAXB.

Therefore, angles ZACB and ZAXB are congruent, and since they are complementary to angles ZAO and ZBO, respectively, they must be supplementary.

Thus, we have proven that ZAXB and ZACB are supplementary.

Therefore, the proof is complete.

The volume of sand in the rectangular prism is 80 percent of the total volume, which can be written as:

0.8 x V = 0.8(L x W x H) cubic inches

A three-dimensional object with six faces, including two at the top and bottom and four lateral faces, called a rectangular prism. The prism's faces are all rectangular in shape. There are three sets of identical faces as a result.

We need to know the dimensions of the rectangular prism to solve the problem. Let's assume the dimensions are length = L inches, width = W inches, and height = H inches.

The volume of the rectangular prism is given by V = L x W x H cubic inches.

If the rectangular prism is filled 80 percent with sand, then 20 percent of the volume is empty space. So, the volume of sand in the rectangular prism is 80 percent of the total volume, which can be written as:

0.8 x V = 0.8(L x W x H) cubic inches

(B) The expression (AB)(x) represents the area of the rectangular tile in square inches.

What is an algebraic expression?

An algebraic expression is a mathematical phrase that contains variables, constants, and mathematical operations. It may also include exponents and/or roots.

A(x) represents the length of the rectangular tile in inches, and B(x) represents the width of the rectangular tile in inches.

A)

To find (A+B)(x), we add the expressions A(x) and B(x):

(A+B)(x) = A(x) + B(x)

= x² + 5 + 2x - 1

= x² + 2x + 4

When x=4, (A+B)(4) = 4² + 2(4) + 4 = 24. This means that the sum of the length and width of the tile when x=4 is 24 inches.

To find (AB)(x), we multiply the expressions A(x) and B(x):

(AB)(x) = A(x) * B(x)

= (x² + 5)(2x - 1)

= 2x³ + 3x² - 5x - 5

When x=4, (AB)(4) = 2(4)³ + 3(4)² - 5(4) - 5 = 91. This means that the area of the rectangular tile when x=4 is 91 square inches.

B)

The expression (AB)(x) represents the area of the rectangular tile in square inches. This is because the product of the length (A(x)) and width (B(x)) of a rectangle gives its area. So (AB)(x) is the formula for the area of the rectangular tile, which is a quadratic function of x.

Step-by-step explanation:

The surface area and volume of a cube with different edge length are

When a cube with edge length 4inches ,

Surface area = 96 square inches and Volume =64 cubic inches.

Cube dilated by scale factor 0.25 ,  

Surface area = 6 square inches and Volume =1 cubic inches.

The surface area of a cube is = 6 times the area of one face.

Each face of this cube has an area equals to

= (4 inches) x (4 inches)

= 16 square inches,

So the total surface area is,

Surface area

= 6 x 16 square inches

= 96 square inches

The volume of a cube =  length of one edge cubed.

Here, the edge length is 4 inches,

Volume

= (4 inches)^3

= 64 cubic inches

When a cube is dilated by a scale factor of 0.25, all of its edges are multiplied by 0.25.

This implies,

The edge length of the image cube is

0.25 x 4 inches = 1 inch.

Surface area of the image cube =  6 times the area of one face.

Each face of the image cube has an area of

= (1 inch) x (1 inch)

= 1 square inch,

So the total surface area is,

Surface area

= 6 x 1 square inch

= 6 square inches

Volume of the image cube = length of one edge cubed.

Here, the edge length is 1 inch,

Volume

= (1 inch)^3

= 1 cubic inch

Therefore, the surface area and volume for the given dimensions are

For edge length 4inches , Surface area = 96 square inches and Volume =64 cubic inches.

For scale factor 0.25 ,  Surface area = 6 square inches and Volume =1 cubic inches.

The equation of the line 2x + 3y + 1 = 0 after it has been reflected across y = -1 and rotated about O(2,3) by 180 degrees is -2x + y = 15.

To reflect the line 2x + 3y + 1 = 0 across the line y = -1, we need to subtract twice the y-coordinate of each point on the line from the equation of the line.

This is because the reflection of a point across a line is obtained by reflecting it across the line's perpendicular bisector, which is also the line with the same x-coordinates and twice the distance from the point to the line.

Subtracting twice the y-coordinate, we get:

2x + 3(-2y - 1) + 1 = 0

Simplifying the equation, we get:

2x - 6y - 5 = 0

Now, to rotate the line about the point O(2,3) by 180 degrees, we can use the rotation formula:

x' = 2a - x

y' = 2b - y

where (x,y) are the coordinates of a point on the original line, and (x',y') are the coordinates of the same point after rotation about the point (a,b).

Substituting the coordinates of two points on the line, we get:

(0,-1) → x' = 2(2) - 0 = 4, y' = 2(3) - (-1) = 7

(-1/2,0) → x' = 2(2) - (-1/2) = 4 1/2, y' = 2(3) - 0 = 6

Now, we can use the two points (4,7) and (4 1/2,6) to find the equation of the rotated line using point-slope form:

slope = (6-7) / (4 1/2 - 4) = -2

y - 7 = -2(x - 4)

Each person would receive 10.67π square inches of pizza.

If 12 friends shared 8 small pizzas equally, we need to determine the amount of pizza each person would receive. To do this, we can start by calculating the total amount of pizza in all 8 small pizzas.

Assuming that each small pizza has the same size, we can divide the total amount of pizza by the number of people sharing it to get the amount of pizza each person would get.

Let's assume that each small pizza has an area of 10 square inches, for a total area of 80 square inches for 8 small pizzas. Dividing this area equally among 12 people, each person would receive approximately 6.67 square inches of pizza.

Alternatively, if we assume that each small pizza has a diameter of 8 inches, we can use the formula for the area of a circle to calculate the total area of each small pizza:

Area = π x (radius)^2

Area = π x (4 inches)^2

Area = 16π square inches

For 8 small pizzas, the total area would be:

Total area = 8 x 16π = 128π square inches

Dividing this area equally among 12 people, each person would receive approximately 10.67π square inches of pizza.
