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 50 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, 25); y = one over one hundredx2 − 25
(0, 50); y = one over two hundredx2 − 50
(0, 25); y = one over one hundredx2 + 25
(0, 50); y = one over two hundredx2 + 50
