Acountry's population in 1993 was 94 million. in 1999 in was 99 million. estimate the population in 2005 using the exponential growth formula. round your answer to the nearest millionth. p=ae^kt

Let P(t) denote the population at t years after 1993, then 

P(0) = 94 million 
P(6) = 99 million 

P(t) = P(0) e^(k t) 

Therefore 

P(6) = P(0) e^(6 k) 

99 = 94 e^(6 k) 

e^(6 k) = 99/94 

6 k = ln (99/94) 

k = ln (99/94) / 6 = 0.0086375 

Now that we have the value of k, we can estimate the populatioin 
in 2005 

t = 2005 - 1993 = 12 

P(12) = P(0) e^( 12 k) = 94 e^( 12 (0.0086375) ) = 104.266 million

I hope my answer has come to your help. Thank you for posting your question here in .

i believe it's a.

i'm not sure on this one, most likely correct.

good luck!
