A population of ameba grows according to an exponential growth model. The size of the ameba colony is determined by measuring the diameter across it (in centimeters). The initial population size is P0=9 P0=9centimeters, and the population 1 hour later is P1=11.25
P1=11.25
centimeters. Answer the following questions:

Then:
P2=

Find an explicit formula for Pn Your formula should involve n
Pn=

Use your formula to find
P10 =

Give all answers accurate to at least one decimal place

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!

you already gave the answer

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
