Question 1 (1 point)

A bacteria culture started with 200 bacteria at 2 p.m. After 1 hour, the population
has grown to 240 bacteria. Assume the population grows exponentially.
1. Find an explicit formula the gives the number of bacteria n hours after 2 p.m.
2. Use your formula to find the number of bacteria at 9 p.m. Round your answer
to nearest integer.

Answer 1

Hello, Elyna. ,

The formula would be:

200+200x=b

Step-by-step formula:

1.) x equals hours, whereas b equals bacteria.

2.) There are 24 hours in one day.

3.) 24*5= 120

4.) Connect it.

5.) 200+200(120)= 6.) 24200= 5 bacterium days

Hope I could help.
