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.

i take 75 plus 50.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
