Hi! I really need help!!! A population, P(t) (in millions) in year t, increases exponentially. Suppose P(7)=25 and P(16)=31.

a) Find a formula for the population in the form P(t)=abt. Enter the values you found for a and b in your formula in the blanks below. Round your values to 4 decimal places.
a=
b=

b) If P(t)=aekt, what is the value of k in your formula.
k=
(round to 4 decimal places)

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.
