x = 4 - 1.5
x = 2.5 meters per second
The initial population was 234.
<em><u>Explanation</u></em>
<u>Formula for the exponential growth</u> is: , where P is the initial amount, A is the final amount, r is the rate of growth and t is the time duration.
There was 337 bacteria after 5 minutes and 699 bacteria after 15 minutes. So, the equations will be......
Now dividing equation (2) by equation (1) , we will get .......
<u>Taking 'natural log'</u> on both sides.........
Now, plugging this into equation (1), we will get......
So, the initial population was 234.
