Math Problem Statement
A population of bacteria follows the continuous exponential growth model Upper P left parenthesis t right parenthesis equals Upper P 0 e Superscript kt, where t is in days. The relative (daily) growth rate is 3%. The current population is 888.
A) Find the growth model. (the function that represents the population after t days) P(t)= what?
B) Find the population exactly 3 weeks from now. Round to the nearest bacterium. The population in 3 weeks will be what?
C) Find the rate of change in the population exactly 3 weeks from now. Round to the nearest unit. The population will be increasing by about what bacteria per day exactly 3 weeks from now.
D) When will the population reach 6664? ROUND TO 2 DECIMAL PLACES. The population will reach 6664 about what days from now.
