I have 2 questions: 1. What are the coordinates of the image of A(-2, 7) after a dilation with a center at the origin and a scale factor of 2?

(1) A'(-5, 4)

(2) A-(-4, 14)

(3) A'(-6, 21)

(4) A'(1, 10)

2. For two similar figures, which of the following statements is true?

(1) corresponding sides and angles are proportional with the same constant of proportionality

(2) corresponding sides are proportional and corresponding angles are congruent

(3) corresponding sides and corresponding angles are congruent

(4) corresponding angles are proportional and corresponding are congruent

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
