Question

The amount of bacteria after n min if the initial amount of bacteria is q and the amount of bacteria triples every 30 sec. (Hint: The answer should contain q as well as n.)

population doubles twice every minute. After n minutes,

a = q*3^(2n)

Answer 2

q=bacteria
r=3 (triples)
60÷30=2 (60 sec. in one minute divided by 30 sec.)
Solution:
q(3 to the second power n)
