Question

Geometry. A dilation maps A to A' and B to B'. find the scale factor of the dilation. Find the center of the dilation.

Answer 1

A(4,2) A'(5,1) B(10,6) B'(8,3)

Answer 2

@Compassionate

Answer 3

A(4,2) A'(5,1) This is our image after it's been dilated
B(10,6) B'(8,3) This is our image before it's been dilated.

Do you see a pattern here? They were multiplied by what?

Answer 4

no i dont see the pattern

Answer 5

@Compassionate

Answer 6

Yes. One moment

Answer 7

Is there an image or anything to go along with this?

Answer 8

yes hold on

Answer 9

@Compassionate

Answer 10

This seems real of context. What are those images? I know how to do all of this, but I'm so lost within the context it's insane.

Answer 11

those images don't have anything to do with the problem. it's a worksheet and im really confused with those problems @Compassionate

Answer 12

I am confused as you are because I have no idea what it's asking. I know how to do everything it is asking; but the way it is asking me is absolutely absurd. Is this common core?

@texaschic101

Answer 13

yes it is common core. I just dont really get how to get the center of dilation

Answer 14

Have you learned like matrices as transformations?

Answer 15

yes i have

Answer 16

so is can anyone help?

Answer 17

@Compassionate can you do this?

Answer 18

I know it but don't understand it. That's why I tagged

Answer 21

@wio

Answer 22

Find the distance between \(A\) and \(B\), then find the distance between \(A'\) and \(B'\).

Answer 23

The ratio between these differences is the answer

Answer 24

what about for the center of dilation
