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 = 2t2 - 4; when t = 6; use values of t of 5.5, 5.9, 5.99, 5.999
A. Average velocities: 23.5, 23.9, 23.99, 23.999
v = 24 ft/s
B. Average velocities: 23, 23.8, 23.98, 23.998
v = 24 ft/s
C. Average velocities: 11.5, 11.9, 11.99, 11.999
v = 12 ft/s
D. Average velocities: 11, 11.8, 11.98, 11.998
v = 12 ft/s
