The number of bacteria in a petri dish increases according to the functiony = 1000(3.7^x), where x is the number of hours. how many bacteria willthere be after 3 hours? oa) 3700ob) 35,650oc) 50,653od) 63,505

C) 50,653

Step-by-step explanation:

y = 1000(3.7)^x

After 3 hours   x=3

y = 1000(3.7)^3

y = 1000(50.653)

y =50653

OPTION C

Step-by-step explanation:

You know that in the function the variable "y" is the number of bacterias in a petri dish  and the variable "x" is the number of hours.

Then, to answer the question "How many bacteria will there be after 3 hours?", you need to substitute into the function.

Therefore, the number of baterias after 3 hours will be:

This matches with the option C.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
