Solve the problem.A satellite dish is shaped like a paraboloid of revolution. The signals that emanate from a satellite strike the surface of the dish and are reflected to a single point, where the receiver is located. If the dish is 8 feet across at its opening and is 2 feet deep at its center, at what position should the receiver be placed?
What will be an ideal response?
The receiver should be located 2 feet from the base of the dish, along its axis of symmetry.
