Are ya sure katherine?

katherine:

Yes, I'm sure.

zarkam21:

These are exam prep questions so I want to make sure they are correct, could you explain ?

katherine:

\(6000 = 20(e^(2.5t)\) <---- Is the formula (Which is the population of Bacteria) \(300 = e(2.5t)\) (How I got 300 is \[6000\div20\] ln(300) = 2.5t t = ln(300) / 2.5 = 2.28151299 hours ==> 2 hours

katherine:

The question asks for a number (Hour) not a word. Don't get those confused.

zarkam21:

oh okay

katherine:

dw, You're not the only one. I failed a test once cause I put a word. Also, it's good to double read what the questions asks :)

katherine:

nope that's all for now =) Thank you so much for the explanation, I will tag you if I need more help

katherine:
