To show that circle P is similar to circle Q, circle P is translated t units to the right. The image is then dilated about its center by a scale factor of s. What are the values of t and s? A. t=13 and s=1.75. B. t=5 and s=1.75. C. t=8 and s=0.57. D. t=13 and s=0.57. The smaller circle has (-5, 6) and the big circle has (8, 6).

Answer: A. t = 13 and s = 1.75.

Reason: Translate center from x = −5 to x = 8: t = 8 − (−5) = 13. The big circle’s radius is 7 and the small circle’s radius is 4, so scale factor s = 7/4 = 1.75.
