The Golden Gate bridge in San Francisco is a large suspension bridge. The cable joining the two towers of the bridge (see illustration) can be modeled by the equation 3 8000 20 where y is the height of the cable above the bridge deck in metres and x is the horizontal distance from the left tower in metres. y = x+155 What is the distance between the towers? (Hint: both towers are the same height. The left hand tower is at x = 0) Show full working on your handwritten working. Width between towers = metres. What is the minimum height of the cable above the deck of the bridge? Show full working on your handwritten notes. Minimum height of cable above deck= metres.
