Question

PLEASE HELP ME WITH THIS!! I’ve stuck on this question for a past hour.

Answer 1

`\sf a. \quad Scale\;factor=(10)/(9)`

b. Enlargement.

Explanation:

The original figure is called the "pre-image".

The new, transformed figure is called the "image" and is usually indicated by the addition of ' after the name.

Therefore:

• CP is the pre-image.
• CP' is the image.

To find the scale factor of dilation, divide the dimension of the image by the dimension of the pre-image.

`\implies \sf Scale\;factor=(CP')/(CP)=(20)/(18)=(10)/(9)`

As the image is larger than the pre-image (and the scale factor is larger than 1), the dilation is an enlargement.
