A satellite dish has a shape called a paraboloid, where each cross-section is a parabola. Since radio signals (parallel to the axis) will bounce off the surface of the dish to the focus, the receiver should be placed at the focus. How far (in ft) should the receiver be from the vertex, if the dish is 12 ft across, and 4.5 ft deep at the vertex? (Type in the number only.) *
