Tanzania [10]

Answer:

A = 236,000 (1.04)^t

population in 2009 : 335,902 people

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:  

A = P (1 + r) t  

Where:  

p = original population  

r = growing rate (decimal form) = 4/100 = 0.04

t= years passed from 2000

A = population after t years  

Replacing with the values given:  

A = 236,000 (1+ 0.04)^t

A = 236,000 (1.04)^t

Population in 2009.

t = 2009-2000 = 9  

A = 236,000 (1.04)^9

A = 335,902 people

Feel free to ask for more if needed or if you did not understand something.
