A study is done on the number of bacteria cells in a petri dish. Suppose that the population size PC) after thours is given by the following exponential functionP (t) = 2000(1.09)By what percent does the population size change each hour?

Respuesta :

Give the following equation:

[tex]\text{ P(t) = 2000(1.09)}^t[/tex]

1.09 represents the growth rate. It means that the population increases by 9% each hour, (1 + r).

The answer is 9%.
