A biologist studying a population of geckos for several years found that the population can be modeled as where P is the population, and t is in the time in years. P= 230( 1.04)^t . What is the growth rate of this population?

Annual growth is
Explanation:
Take your growth equation and plug some numbers in:
-
t = 0, P = 230(1.04)^0 = 230 -
t = 1, P = 230(1.04)^1 = 230(1.04) -
t = 2, P = 230(1.04)^1 = 230(1.04)^2
You should see that there annual growth is by a factor of
So annual growth is
