Q:

WILL GIVE BRAINLIEST... HELP ASAP!!!!!!1. Circle A with center at (3, 4) and radius 2 is similar to circle B with center at (βˆ’4, βˆ’5) and radius 3. Below is an incorrect informal argument for proving two circles are similar:Step 1 Translate circle B to the right 9 units and up 7 units to form concentric circles.Step 2 Dilate circle B to be congruent to circle A using scale factor of k = r sub two over r sub one equals two over threeStep 3 When an object is dilated, the dilated object is similar to the pre-image, thus the two circles are similar.What is the first incorrect step, and how can it be fixed?A. All steps are correctB. Step 1, translate circle B to the right 7 units and up 9 unitsC. Step 2, use scale factor of K= r^2/r^1=3/2D. Step 3, replace dilated with translated.An image of two concentric circles is shown with r2 = 8 and r1 = 3:2. Image shows a pair of concentric circles. The radius of the smaller circle is r sub 1 and the radius of the second is r sub 2.In order to prove the two circles are similar, the radius r1 was increased to make the circles congruent. What is the scale factor used in the above image?A. k=8/3B. K=3/8C. K=1/5D. K=5

Accepted Solution

A:
The anwser is B, k= 3/8
