A skateboard halfpipe is being designed for a competition. The halfpipe 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 halfpipe be positioned? Which equation best describes the equation of the halfpipe? (0, 20); y equals one over eighty times x squared plus 20 (0, 10); y equals one over one hundred twenty times x squared plus 10 (0, 20); y equals one over eighty times x squared minus 20 (0, 10); y equals one over one hundred twenty times x squared minus 10
