Question

If there are initially 2000 bacterial in a culture, and the number of bacteria doubles each hour, the number of bacteria after t hours can be found using the formula N = 2000(2t). How many bacteria will be present after 7 hours?

Answer 1

Okay, they give you the formula.

t = hours
N = 2000(2(7))
N = 2000(14)
N = 28000

Answer 2

Got it? :P

Answer 3

ooohh no!

Answer 4

Answer 5

\[ N(t) = 2000\times 2^t\] doubles every hour
compute
\[N(7)=2000\times 2^7\]
