You live near a bridge that goes over a river. The underside of the bridge is an arch that can be modeled with the function y=-0.000475x^2+0.851x, where x and y are in feet. How high above the river is the bridge(the top of the arch)? How long is the section of bridge above the arch?

Would appreciate if someone could help me..
