How Do You Calculate Bacterial Growth Using Exponential Equations?

AI Thread Summary
To calculate bacterial growth using exponential equations, the formula A=Pe^(rt) is applied. Given a culture count of 200 after 15 minutes and 1500 after 40 minutes, the goal is to find the population after 120 minutes. An initial attempt yielded an incorrect population estimate of 952,023.0848, suggesting a need for more precision in calculations. It is recommended to retain more decimal points before rounding to improve accuracy in results.

Homework Statement



The count in a bateria culture was 200 after 15 minutes and 1500 after 40 minutes.

Find the population after 120 minutes.

Homework Equations



A=Pe^(rt)

The Attempt at a Solution



I did
P=60e^(.0806 x 120)
P= 952023.0848 (answer is wrong)

Your form also doesn't give quite the right answer for t=15 or t=40. I think you might want to keep more decimal points before rounding off.

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
