EXAMPLE 5 Use graphs of circles EARTHQUAKES The epicenter of an earthquake is the point on Earth's surface directly above the earthquake's origin. A seismograph can be used to determine the distance to the epicenter of an earthquake. Seismographs are needed in three different places to locate an earthquake's epicenter. Use the seismograph readings from locations A, B, and C to find the epicenter of an earthquake. • The epicenter is 7 miles away from A(-2, 2.5). • The epicenter is 4 miles away from B(4, 6). • The epicenter is 5 miles away from C(3, -2.5).
