The figure shows a shot-put ring. The shot is tossed from A and lands at B. Using modern electronic equipment, the distance of
the toss can be measured without the use of measuring tapes.
When the shot lands at B an electronic transmitter placed at B
sends a signal to a device in the official's booth above the track.
The device determines the angles at B and C. At a track meet, the
distance from the official's booth to the shot-put ring is 575 feet. If
B = 85.6° and C=5.7°, determine the length of the toss to the
nearest tenth of a foot.

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
