Unit 3, Activity 2, Continuous Growth and the Number e with Answers Blackline Masters, Advanced Math-Pre-Calculus Page 89 Comprehensive Curriculum, Revised 2008 1. In each of the following equations tell whether or not there is growth or decay and give the continuous rate of growth or decay. a) A = 1000 e 0.08t growth of 8% b) A e t = 200 2 . decay of 20% c) t oo o e A 4 . 4 . 2 = decay of .4% 2. Write the following exponential functions in the form P = a t a) P = e .25t be = .25 so P = (1.28) t b) P = e -.4t = 04 . so P = (.67) t 3. The population of a city is 50,000 and it is growing at the rate of 3.5% per year. Find a formula for the population of the city at time t years from now if the rate of 3.5% is: a) an annual rate and b) a continuous annual rate.
