In a Petri dish a certain type of bacterium doubles in number every 40 minutes there were originally 64,or 2^6,bacteria in the dish after 120 minutes the number of bacteria has doubled 3 times multiplying by 2^3 now the population of bacteria is 2^6•2^3.Expressed as a power, how many bacteria are in the Petri dish after 120 minutes

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

a is the correct

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!

the answer is c.
