The function s gives the displacement (in ft) of an object as a function of time (in seconds). Calculate values of the average velocity for the given values of t and find the instantaneous velocity at the indicated value of t by noting the limit of the average velocities.s = 80t - 18t2 ; when t = 0.5; use values of t of 0.45, 0.49, 0.499, 0.4999
A. Average velocities: 22.9, 22.18, 22.018, 22.0018
v = 22 ft/s
B. Average velocities: 44.9, 44.18, 44.018, 44.0018
v = 44 ft/s
C. Average velocities: 62.9, 62.18, 62.018, 62.0018
v = 62 ft/s
D. Average velocities: 4.9, 4.18, 4.018, 4.0018
v = 4 ft/s

Solve the problem.An experimental model for a suspension bridge is built in the shape of a parabolic arch. In one section, cable runs from the top of one tower down to the roadway, just touching it there, and up again to the top of a second tower. The towers are both 12.25 inches tall and stand 70 inches apart. At some point along the road from the lowest point of the cable, the cable is 1.1 inches above the roadway. Find the distance between that point and the base of the nearest tower.
