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

Hi there

The exponential growth equation of
the number of bacteria doubles each hour is
N=2000 (2)^t
Where t is the number of hours
T=7 hours

So the number of bacteria after 7 hours is

N=2,000×(2)^(7)
N=256,000....answer

Good luck

Answer 2

Answer:

Time (seconds of video), t  |   0 1 2 3

Number of Bacteria, B(t)     |   2    4      8      16

The bacteria count at the end of the first hour is  16 .
