Which transformation shows that the two given circles are similar? circle a -- center(2, 0), radius 8 circle a' -- center(-1, 5), radius 3 a)(x, y) → (x - 3, y + 5); scale factor 3/8 b)(x, y) → (x - 3, y + 5); scale factor 8/3 c)(x, y) → (x + 3, y - 5); scale factor 3/8 d)(x, y) → (x + 3, y - 5); scale factor 8/3

What we know:
Circle A has a center at (2,0) and a radius of 8
Circle A' has a center at (-1,5) and a radius of 3

What we need to find: 
we need to find the transformation from the center point of A to A' and the scale factor 

Circle A can be mapped to Circle A'
center point translation (x,y)⇒[(x+a),(y+b)]⇒(x-3, y+5)

2+a=-1                                      0+b=5
-2+2+a=-1-2                                  b=5
a=-3

scale factor is 3/8
8x=3
8/8x=3/8
x=3/8

A)(x, y) → (x - 3, y + 5); scale factor 3/8 

The answer would be $68.04

1/6 of a chance i would believe
