Solve the problem.A satellite dish is in the shape of a parabolic surface. Signals coming from a satellite strike the surface of the dish and are reflected to the focus, where the receiver is located. The satellite dish shown has a diameter of 6 feet and a depth of 6 feet. The parabola is positioned in a rectangular coordinate system with its vertex at the origin. The receiver should be placed at the focus src="https://sciemce.com/media/4/ppg__10626191641__f1q182g3.jpg" alt="" style="vertical-align: -4.0px;" />
