Suppose that three geological study areas are set up on a map at points A(-9, -13), B(-5, -2), and C(0, -12), where all units are in miles. Based on the speed of compression waves, scientists estimate the distances from the study areas to the epicenter of an earthquake to be 13 mi, 10 mi, and 5 mi, respectively. Graph three circles whose centers are located at the study areas and whose radii are the given distances to the earthquake. Then estimate the location of the earthquake.
