Follow the pattern. How many million bacteria were in the dish at

1 p. m. and 12 p. m.?

Hour Number of Bacteria (in millions)

12 p. m.

✓ DONE

1 p. m.

2 p. m.

3 p. m.

4 p. m.

32

6 p. m.

64

5 p. m.

Step-by-step explanation:

Given the information on the table

We are to follow the pattern to determine how many million bacteria were in the dish at  1 p.m. and 12 p.m.

Now:

It therefore means that the bacteria population doubles every hour. Following this pattern and reducing the exponents by 1 backwards, we have:

Therefore:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

i’m sorry but i don’t know sorry
