Question 1001106
 In 2012, the population of Uganda was 36.35 million people 
and it is growing at a rate of 2.9% per year.
a. Is this population growth linear or exponential?
Ans: exponential
-----------------
b. Model this situation with an equation P(t).
Ans: P(t) = (36.35 million)*1.029^t
---------------------------------------------------
c. Use your model to determine what the population of Uganda will be in 2017?
P(5) = (36.35 million)*1.029^5 = (41.94 million)
----------------------------------
d. In what year will the population of Uganda be 55 million?
Solve::
(55 million) = (36.35 million)1.029^t
----
1.029^t = 1.5131
----
t = log(1.5131)/log(1.029) = 14.49 years
Ans: 2012 + 14.49 = 2026.49 or "in the year 2027".
