Step-by-step explanation:
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.
The length of each side is 12cm.
Answer:
any value less than 10
Step-by-step explanation:
Let x represent the number.
1.5x < |20 -5|
1.5x < 15 . . . . simplify
x < 10 . . . . . . divide by 1.5
The number may be any value less than 10.
