In a lab experiment, the count of a bacteria doubles every hour.

a)at 1pm, there was 23000 bacteria. How many bacteria will be present at midnight?

I can't seem to get the correct answer.

The answer is 47 104 000 bacteria.

Thanks very much in advance!

Whoops, never mind, I got the answer.

To find the number of bacteria present at midnight, we need to determine the number of doublings that occur from 1 pm to midnight (a span of 11 hours).

Since the number of bacteria doubles every hour, we can set up a simple equation to represent this exponential growth:

Number of bacteria at midnight = Initial count * (Doubling factor) ^ (Number of hours)

Let's break down the steps to calculate the answer:

1. Determine the doubling factor:
Since the count doubles every hour, the doubling factor is 2.

2. Calculate the number of hours from 1 pm to midnight:
There are 11 hours from 1 pm to midnight.

3. Plug the values into the equation:
Number of bacteria at midnight = 23,000 * 2^(11)

Calculating the result:
Number of bacteria at midnight = 23,000 * 2^11
= 23,000 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2
= 23,000 * 2,048
= 47,104,000

Therefore, there would be approximately 47,104,000 bacteria present at midnight.
