Answer:
A)(x, y) → (x - 3, y + 5); scale factor 3/8
Step-by-step explanation:
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
