The emergency radio broadcast system is designed to alert the population by relaying an emergency signal to all points of the country. A signal is sent from a station whose broadcast area is bounded by x2 + y2 = 2500 (x and y in miles) and the signal is picked up and relayed by a transmitter with range (x - 20)2 + (y - 30)2 = 900. Graph the circle representing each broadcast area on the same grid to determine the greatest distance from the original station that this signal can be received. Be sure to scale the axes appropriately.
