Extracted text: The profile of the cables on a suspension bridge may be modeled by a parabola. The central span of the bridge is 1260 m long and 147 m high. The parabola y=0.00037x gives a good fit to the shape of the cables, where xs 630, and x and y are measured in meters. Use a midpoint Riemann sum with n = 10' approximate the length of the cables that stretch between the tops of the two towers. = 107
