A biologist compares the growth rates of two types of bacteria. The bacteria in Sample A grows linearly according to the formula c = 15h + 10, where c is the number of colonies present h hours after the experiment begins. The two samples have the same number of colonies at h = 2 and h = 6. If the colonies in Sample B grow exponentially, which equation could express Sample B's growth rate?

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.

Which is the scale factor proportion for the enlargement shown?
