How do you find a scale factor of dilation?

Answer 1

Answer 2

A dilation is a transformation (notation ) that produces an image that is the same shape as the original, but is a different size. A dilation stretches or shrinks the original figure. The description of a dilation includes the scale factor (or ratio) and the center of the dilation.

Answer 3

i looked tht up but i need an easier way to figure it out

Answer 4

okay suppose that we have the following point A(2,4) we want to make a dilation by scale factor of 2 the rule of dilation is (kx,ky) where k is the scale factor
so A'(2*2, 2*4) --> A'(4,8) make sense?

Answer 6

and keep in mind that in dilation the measure of the sides never remain the same
it either grow or shrank

Answer 7

so how would i figure this out?

Answer 8

would i b 2?

Answer 9

what you mean b 2?

Answer 10

the answer choices for the scal factor is 1, 1.25. 2, and 2.5

Answer 11

i know some facts here and i shall discover the others
here's what i know so far
i know that the dilation from AB to A'B' is growing nor shrank so that means the scale factor should be over 1 so that eliminate the option 1

Answer 12

nvm i figured it out thank you!!

Answer 13

it was 2

Answer 14

enlighten me
how did you know

Answer 15

and i suspected to be either 2 or 2.5

Answer 16

honestly idk how i got it
