I'm desperate! i don't understand.

D ' (-7, 7) , E ' (-3.5, 14) ,  F ' (7, 10.5) , G ' (-3.5, -7)

Explanation:

Point D has coordinates x = -2 and y = 2. Multiply each by the scale factor 3.5 to get

3.5*(-2) = -7

3.5*(2) = 7

Therefore the new location is now (-7, 7) which is where point D ' is at.

The same idea applies to all of the other points

E(-1, 4) > E ' (-3.5, 14) after multiplying both coordinates by 3.5

F(2, 3) > F ' (7, 10.5) doing the same to the coordinates of point F

G(-1, -2) > G ' (-3.5, -7) ditto to the coordinates of point G

Extra info: the preimage DEFG enlarges to the image D'E'F'G' because the scale factor 3.5 is larger than 1.

its d. the first coordintaes are 10,32

step-by-step explanation:

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
