Answer:
Step-by-step explanation:
Geometric formula sequence:
(where is the first term of the sequence and
is the common ratio)
To find the common ratio, divide one of the terms by the previous term:
From inspection,
Therefore,
<h2>Hello!</h2>
The answer is: 23.77 hours
<h2>Why?</h2>Where:
Total(t) is equal to the amount for a determined time (in hours)
<em>Start</em> is the original amount
<em>t </em>is the time in hours.
For example, it's known from the statement that the bacteria double their population every 15 hours, so it can be written like this:
To calculate how long it takes for the bacteria cells to increase to 300, we should do the following calculation:
So, to know if we are right, let's replace 23.77 h in the equation:
Total(t)=100*2^\frac{23.77}{15}=299.94
and 299.94≅300
