Circle A has center of (4,5) and a radius of 3 and circle B has a center of (1,7) and a radius of 9. What steps will help show that circle A is similar to circle B?

Move the center of circle A to (1,7), then multiply its radius by 3.

Step-by-step explanation:

Moving the circles to the same center would make them concentric.  Then, by multiplying the radius of Circle A by 3, the circle is dilated to the exact size of circle B, since its radius is 9.  This shows that Circle B is proportional to Circle A, thus they are similar.  

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
