. Write the following equation in general form, and then use technology to provide a graph. 42 24252 +250489=0 2. An explosion is recorded by two microphones that are 2 miles apart. Microphone 1 received the sound 3 seconds before microphone 2. Assuming sound travels at 1100 ft/s, determine the possible locations of the explosion relative to the location of the microphones. 3. A lithotripter is used to disintegrate kidney stones. The patient is placed within an elliptical device the kidney centered at one focus, while ultrasound waves from the other focus hit the walls and are reflected to the kidney stone, shattering the stone. Suppose that the length of the major axis of the ellipse is 40 cm and the length of the minor axis is 20 cm. How far from the kidney stone should the electrode that sends the ultrasound waves be placed in order to shatter the stone?
