The profile of the cables on a suspension bridge may be modeled by a parabola. the central span of a bridge is 1270 ft long and 157 ft high. the parabola y=0.00039x^2 gives a good fit to the shape of the cables, where ixi less than of equal to 635, and x and y are measured in feet. approximate the length of the cables that stretch between the tops of the two towers.
