A parachutist jumps out of a plane. Her height, in metres, above the ground after t seconds is given by S(t) = 1750 − 4.9t^2, 0 ≤ t ≤ 19. Estimate the instantaneous rate of change of the parachutist’s height over the interval at t= 8

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
