The population of a country in 2010 was approximately 37 million with an annual growth rate of 0.804%. At this rate, the population P(t) (in millions) can be approximated by P (t) = 37(1.00804)', where t is the time in years since 2010.

The population of a country in 2010 was approximately 37 million with an annual growth rate of 0.804%. At this rate, the population P (t) (in millions) can be
approximated by P (t) = 37(1.00804), where t is the time in years since 2010.
