Question

The number of bacteria in a sample increased by a factor of 2 every minute from 9:05 a.m. to 9:55 a.m. The function below shows the number of bacteria in the sample f(x) after x minutes from 9:05 a.m. :

Answer 1

f(x) = 10(2)^x

Which of the following is a reasonable domain for the function?
(A) 0 ≤ x ≤ 10
(B) 5 ≤ x ≤ 55
(C) 0 ≤ x ≤ 50
(D) All positive integers

Answer 2

\[(A ) 0\le x \le10\]
\[(B) 5\le x \le 55\]
\[(C) 0\le x \le50\]
(D) All positive integers

Answer 3

Is this C? @ganeshie8 @Abhisar @SolomonZelman @AndrewTheCookie

Answer 4

how much time occurs from 9:05 - 9:55?

Answer 5

50 min srry

Answer 6

yes :)

Answer 7

So at the start we can take \(x=0\)

We just found out it took 50 minutes.

Answer 8

Which expression shows that? :)

Answer 9

The third one, right?

Answer 10

yes :)
