Solve.In 1985, the number of female athletes participating in Summer Olympic-Type Games was 550. In 1996, about 3550 participated in the Summer Olympics in Atlanta. Assuming that 
and that the exponential model applies, find the value of k rounded to the hundredths place, and write the function.
A. k = 0.16; P(t) = 500e0.16t B. k = 0.17; P(t) = 500e0.27t C. k = 0.19; P(t) = 500e0.19t D. k = 0.17; P(t) = 500e0.17t
Solve the problem.Let T be the amount of time (in seconds) it takes a baseball to fall to the ground when the ball is dropped from h feet above the ground. A good model is 
Simplify the right-hand side of the equation and determine how long it would take for a baseball to reach the ground if it were dropped from the top of a building that is 930 feet tall. Round to the nearest tenth when necessary.
A. T = 
; 232.5
B. T = 
; 7.6
C. T = 
; 15.2
D. T = 
; 1.9
