Dr. Silas studies a culture of bacteria under a microscope. The function b1 (t) = 1200 (1.8) represents the number of bacteria t hours after Dr. Silas begins her study.

(a) What does the value 1200 represent in this situation?

(b) What does is the percent of growth or decay?

(c) Approximately how many bacteria are present at t = 5 hours?

(d) The number of bacteria in a second study is modeled by the function b2 (t) = 1000 (1.8) ^t. Will the bacteria present in both studies ever be equal for a certain value of t? Why or why not?
