a) Place the origin of an xy-coordinate system at the lowest point of a parabolic cable of a suspension bridge whose span is "L" and sag is "h." Find an equation for the cable.
b) The George Washington Bridge across the Hudson River in New York has a span of 3500 feet and a sag of 316 feet. Find an equation for the cable.
Thanks
