The Golden Gate Bridge was built in 1937. The roadway is 79 metres above the water level. The bridge suspension wire is represented by a quadratic equation that is just at roadway height exactly between the two pylons. the equation for the suspension bridge is H=0.000426(w-650)²
an answer for any of the following questions would be good!
a) Find the x intercepts
b) How wide is the bridge between the pylons?
c) What is the coordinate of the left pylon, on the y-axis, at sea level?
d) Find the y-intercept and determine the height of the pylons from sea level.
