3.

Write the exponential growth function to model the following situation:

A population of 422, 000 increases by 12% each year.

 

 

 

 

5.

At t = 0 there are 50 grams of a radioactive isotope. The isotope has a half-life of 16 minutes. Use the exponential decay model to write the amount A as a function of time t.

First one

 

P = 422000 ( 1 + .12)^t       where P is the population  after t  years

 

 

Second one

 

A = 50 (1/2)^(t/16)       where A is the number of grams remaining after t minutes
