A culture started with 4,000 bacteria. After 7
hours, it grew to 5,200 bacteria. Predict how
many bacteria will be present after 9 hours.
Round your answer to the nearest whole
number.
P= Aekt
Enter the correct answer.

5605

Step-by-step explanation:

5200 = 4000e^(7k)

5200/4000 = e^(7k)

1.3^(9/7) = [e^(7k)]^(9/7)

1.401195054 = e^(9k)

4000e^(9k) = 5604.780218

step-by-step explanation:

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!
