Question

A colony of bacteria is growing exponentially according to the function below, where t is in hours. What will the approximate number of bacteria be after 8 hours?

B(t)=4*e^0.8t

A. 2407
B. 205,968
C. 602
D. 4,289,241

Answer 1

All you have to do here is to express t=8 in function that is given and calculate B(t=8)

B(t=8) = 4 * e^(0.8*8) = 2407.37

if we round it we get that answer is A.
