Answer:
The length of the bridge is 126.492 feet.
Step-by-step explanation:
Let , where is the position from the middle of the bridge, measured in feet, and is the height of the bridge at a location of x feet, measured in feet. In this case, the length of the bridge is represented by the distance between the x-intercepts of the parabola, which we now find by factorization:
(Eq. 1)
Given that the parabola is symmetrical with respect to y-axis, then the length is two times the magnitude of the value found above, that is:
The length of the bridge is 126.492 feet.
