Suppose that triangle ABC is dilated to A’B’C’ by a scale factor of 3 with a center of dilation at the origin. What is the distance from the center of dilation to the midpoint of B’C?

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
