With the widening of the 401 from 4 to 6 lanes, many existing bridges must be modified or rebuilt. An algebraic model for the interior arc of these bridges is given by the equation, h = -0.05x² + 15.3125. The paved section of the highway is 25.6 m wide.
a. Factor the equation of the function to solve the quadratic. Use these factors and other key features to sketch the archway of the overpass using pencil and paper. The y-axis represents the middle of the highway.
b. Will a transport truck 4.1 m high be able to travel in the outside lane under this bridge?
c. If side braces of 3.3m
