Question

In 2005, Bhutan had a population of about 2200000 and an annual growth factor of 1.0211. Let  be the population  years after 2005 assuming growth continues at this rate. 

(a) Write a formula for f(t). 

(b) According to your formula, what was the predicted population of Bhutan in 2012? 

Answer 1

A] f(t) = 2,200,000 • (1.0211)^t

where t = # of years after 2005

B] t= 2012−2005 = 7

f(t) = 2,200,000 • (1.0211)^t

f(7) = 2,200,000 • (1.0211)⁷

f(7) = 2,200,000 • 1.157385

f(7) = 2,546,247
