The cable for a certain suspension bridge is modeled by a parabola with vertex (0, 0) at the center of the bridge. At a point that is 150 ft from the center of the bridge, the height of the cable is 30 ft. Which equation represents the height of the cable at a distance x feet from the center?
Answer
A
y = StartFraction 1 Over 3,000 EndFraction x squared
B
y = StartFraction 1 Over 750 EndFraction x squared
