A suspension bridge is 120 ft long. Its supporting cable hangs in a shapethat resembles a parabola. The function defined by H ( x ) = 1 90 ( x − 60 ) 2 + 30 (where 0 ≤ x ≤ 120 ) approximates the height H ( x ) (in feet) of the supportingcable a distance of x ft from the end of the bridge (see figure). a. What is the location of the vertex of the parabolic cable? b. What is the minimum height of the cable? c. How high are the towers at either end of the supporting cable?

A falling object travels a distance given by the formula d = 6t + 9t2 where d is in feet
and t is the time in seconds. How many seconds will it take for the object to travel
112 feet? Round answer to 2 decimal places. (Write the number, not the units).
