Chapter 8.7, Problem 61E
Bridges A cable of a suspension bridge is suspended between two towers that are 300 feet apart and 80 feet above the road. The cable is in the shape of a parabola whose low point is 20 feet above the road. Find the equation of this cable if the point (0, 0) is the point on the road directly below the low point of the cable.
