Question

An initial number of bacteria presented in a culture is 1,000. This number triples every 30 minutes. Write a function expressing the number of bacteria over time.

Answer 1

tripiling time is

`A=P(3)^ (t)/(r)`
t=time elapsed
r=tripling time
P=initial amount


so



`A=1000(3)^ (t)/(30)`
when time is measured in minutes
if measured in hours then


`A=1000(3)^(2t)` or
`A=1000(9)^(t)`
