Question

Need help it’s really hard

Answer 1

Given:

`OA=3` units

`OA'=9` units

To find:

The scale factor of the dilation.

Solution:

From the given figure it is clear that the center of dilation is point O. Point A' is the image of point A. So,

`\text{Scale factor}=(OA')/(OA)`

Putting the given values, we get

`\text{Scale factor}=(9)/(3)`

`\text{Scale factor}=3`

Therefore, the scale factor of the dilation is 3.
