question 1(a) second part:

 

1.4% of 5655=79.17 increase in population

2022-2010=12 years

79.17*12 years=950.04

5655+950.04=6605.04

roughly 6055 population at 2022

a)  The function we need is this :

 

P(t)  =  5655 (1.014)t

 

b) In 2022, t  = 12......so we have

 

P(12)  = 5655 (1.014)12      ≈  6682
