Abiologist recorded a count of 337 bacteria present in a culture after 5 minutes and 699 bacteria present after 15 minutes. to the nearest whole number, what was the initial population?

The initial population was 234.

Explanation

Formula for the exponential growth 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 .......

Taking 'natural log' on both sides.........

Now, plugging this into equation (1), we will get......

So, the initial population was 234.

if you was gonna solve for a, a is a   < -12

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
