A bird is in a tree 30 feet off the ground and drops a twig that lands on a rosebush 25 feet below. The function h(t)=-16t^2+30, where t represents the time in seconds, gives height h, in feet, of the twig above the ground as it falls. When will the twig land on the bush?

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.
