What is the scale factor of the dilation?

Answer 1

0.5

Explanation:

to whoever finds this long lost question, good luck on ur test lol

Answer 2

Answer: 0.5

Explanation:

Given: Rectangle A′B′C′D′ is the image of rectangle ABCD after a dilation.

Since dilation always produces similar images.

To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides.

AB=|-5-(-8)|=|-5+8|=3 units

A'B'=|-2.5-(-4)=|-2.5+4|=1.5 units

The ratio of the corresponding sides A'B' to AB is given by :-

`(1.5)/(3)=(1)/(2)=0.5`

hence, the scale factor of the dilation = 0.5
