Question

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 1

Answer:

Step-by-step explanation:

h(x)=ax^2

Given h=30 when x=150 we get

a(150)^2=30

a=30/22500=1/750 so

h(x)=x^2/750
