So here we're asked to find the formula for an annual growth factor.
00:06
This is an exponential function.
00:10
So we have to find what p equals f of t, where t is the number of years after 2005.
00:21
So the given information is that in 2005, mutan had a population of 2 ,200 ,000 ,000 ,000.
00:35
2 ,200 ,000 people.
00:41
And every year this population grows by a factor of 1 .0211.
00:52
So if t is the number of years since 2005 where the population was 2 ,200 ,000, then we can write a formula as 2 ,200 ,000 times 1 .0200 ,000 times 1 .0.
01:11
211, so that is our annual growth rate to the t.
01:17
This is our formula.
01:24
Now, we are then asked to find the population of bhutan in 2010.
01:34
So we know that 2010 is five years after 2005...
