Question
A cable of horizontal suspension bridge is supported by two towers 120
feet apart and 40 feet high. The cable hangs in the form of a parabola and
the lowest point of the cable is 10 feet above the floor of the bridge. What
is the equation of the parabola if the origin is the midpoint of the bridge?
x² - 30y + 300 = 0
x²
- 120y - 1200 = 0
Option 1
Option 2
x² - 120y + 1200 = 0
x² - 30y - 300 = 0
Option 3
Option 4
