Asatellite 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 40 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, 20); y = one over eightyx2 + 20 (0, 10); y = one over one hundred twentyx2 + 10 (0, 20); y = one over eightyx2 − 20 (0, 10); y = one over one hundred twentyx2 − 10
