Question 1148951
.
<pre>

(a)  f(t) = {{{33*(1 + 0.018)^t}}} = {{{33*1.018^t}}} millions people;  t in years since the beginning of 2000.



(b)  The problem does not give any information and any rationality to extrapolate back. 



(c)  Annual growth factor is  1+0.018 = 1.018.



(d)  If "a" represents the population (in millions) at some point in time, then an expression in terms of "a" to represent 

     the population exactly 1 year later  is  b = a*1.018.
