Question

PLEASE HELP ASAP!!!

The number of bacteria in a petri dish increases according to the function
y = 1000(3.7^x), where x is the number of hours. How many bacteria will
there be after 3 hours?
OA) 3700
OB) 35,650
OC) 50,653
OD) 63,505​

Answer 1

Answer: OPTION C

Explanation:

You know that in the function
`y = 1000(3.7^x)` 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
`x=3` into the function.

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

`y = 1000(3.7^3)`

`y = 1000(50.653)`

`y = 50,653`

This matches with the option C.

Answer 2

C) 50,653

Explanation:

y = 1000(3.7)^x

After 3 hours x=3

y = 1000(3.7)^3

y = 1000(50.653)

y =50653
