A new bridge is being constructed. The space between the support needs to be 1050 feet; the height at the center of the arch needs to be 350 feet. An empty tanker needs a 280 foot clearance to pass beneath it.

a) find the equation of a parabola with these characteristics. Place the vertex at the origin.

b) How wide is the channel that the tanker can pass through?

c) If the river were to flood and rise 10 feet, how would the clearance of the bridge be affected?
