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 = 5t - 4; when t = 4; use values of t of 3.5, 3.9, 3.99, 3.999
A. Average velocities: 19.5, 19.9, 19.99, 19.999v = 20 ft/s
B. Average velocities: 20, 20, 20, 20v = 20 ft/s
C. Average velocities: 5, 5, 5, 5v = 5 ft/s
D. Average velocities: 4.5, 4.9, 4.99, 4.999v = 5 ft/s
