Question

HELP ASAP!!!!!!!!!! Please

A certain population of bacteria has an average growth rate 2%. The formula for the growth of the bacteria population is A= p 0• 1.02^t where p0 is the original population and t is the time in hours

If you began with 200 bacteria, about how many bacteria will be their after 100 hours

A)7

B)272

C)1,449

D)20,000

Answer 1

I believe it's C

Explanation:

Hope this helps :)

Answer 2

C

Explanation:

Growth can be represented by the equation
`A=A_01.02^(t)`. We know that r=2% or 0.02 in this situation so we have 1.02. We know t=100 hours and the starting population A=200. We substitute these values and use a calculator to evaluate.

`A=A_01.02^(t)\\A=200(1.02)^(100)`

We now use our calculator to evaluate the exponent first and then multiply by 200.

`A=200(7.2446)=1448.93`
