Question

A particular strain of bacteria triples in population every 45minutes. assuming you start with a 50 bacteria in a petri dish, how many bacteria will there be in 4.5 hours?

Answer 1

ok, so it goes like this

A=future amount
P=present amount
h=trippling time
t=time elapsed

the formula is

`A=P(3)^ (t)/(h)`
so
P=50
h=45min
t=4.5hr or 270mins


`A=50(3)^ (270)/(45)`

`A=50(3)^6`
A=50(729)
A=36450

answer is 36450

Answer 2

your answer will be 36,450
