The count in a bacteria culture was 900 after 20 minutes and 1400 after 35 minutes, Asturning the count grows exponentially,
What was the initial size of the culturel
Find the doubling period,
Find the population after 115 minutes,
When will the population reach 15000,
minutes

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
