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?

Respuesta :

your answer will be 36,450

ok, so it goes like this

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

the formula is
[tex]A=P(3)^ \frac{t}{h} [/tex]
so
P=50
h=45min
t=4.5hr or 270mins

[tex]A=50(3)^ \frac{270}{45} [/tex]
[tex]A=50(3)^6 [/tex]
A=50(729)
A=36450

answer is 36450
