A satellite dish is being designed so that it can pick up radio waves coming from space. The satellite dish will be in the shape of a parabola and will be positioned above the ground such that its focus is 30 ft above the ground. Using the ground as the x-axis, where should the base of the satellite be positioned? Which equation best describes the equation of the satellite? (0, 60); y = one over two hundred fortyx2 + 60
(0, 15); y = one over sixtyx2 + 15
(0, 60); y = one over two hundred fortyx2 − 60
(0, 15); y = one over sixtyx2 − 15
