15.A satellite dish has a shape called a paraboloid, so that Ito crous-sections through its center (lowest paint) are parabolas, alt having the samo focus. Radio signals sent to it bounce off the surface and are reflected to the focus. The receiver is then placed at the focus. It the satelite dish is 3 m across and 0.625 m deep at ils center, how far should the receiver be from the center?
