Asubmarine descends from sea level to the entrance of an underwater caves. the elevation of the entrance is 120 feetv. the rate of change in the submarine elevation is no greater than -12 feet per second can the submarine reach the entrance to the cave in less than 10 seconds explain

Part a : solve - vp + 40 < 65 for v . part b : solve 7w - 3r = 15 for r show your work!

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.
