Suppose the population of trout in a certain stretch of a river is 4000. In about how many years will the population of trout be 700 if the decay rate is 35%? Use the equation 700 = (4000)(0.65)x and round the value of x to the nearest year.

Best ResponseYou've already chosen the best response.0actually its 1 year 700=4000(0.65)^x 7000/4000=4000/4000(0.65)^x 7/4=(0.65)^x log(7/4)=log(0.65)^x 0.24=xlog(0.65) x=0.24/(0.187) x=1.28 x=1 year

Best ResponseYou've already chosen the best response.0\(700 = (4000)(0.65)^x\\\dfrac{700}{4000}=0.65^x\\\ln(\dfrac{700}{4000})=\ln(0.65)^x=x\ln(0.65)\\ x=\dfrac{\ln(\dfrac{700}{4000})}{\ln(0.65)}\approx 4.04605\) or \(700 = (4000)(0.65)^x\\\dfrac{700}{4000}=0.65^x\\\log_{0.65}(\dfrac{700}{4000})=\log_{0.65}(0.65^x)=x\\x\approx 4.04605\)

Best ResponseYou've already chosen the best response.0Are you asking me if the closest whole number to \(4.04605\) is \(4\)?

Best ResponseYou've already chosen the best response.0well I'm just confused now because it was 4 then it wasn't then it was 1 then I tried it on my own and got 3 somehow. It really was a rhetorical question.

Best ResponseYou've already chosen the best response.0Meaning and intent aren't the same thing, so oop @ you. I'm not bothered though.

Best ResponseYou've already chosen the best response.0Meaning is actually synonymous to intent?

Best ResponseYou've already chosen the best response.0no need for confirmation. check your answers! If I am right, then \(4000*0.65^{4.04605}=700\) Get your calculators out!!!

Best ResponseYou've already chosen the best response.0Not really how something means to me isn't the same as how you meant something to be. English isn't my first language so maybe that's why you didn't understand.

Best ResponseYou've already chosen the best response.0I fully understand that you are being a baby. Just say thanks for the help and move on :) It was funny. I know you were not asking me to round it for you, but I wanted to point out that it was a weird question. Also your reply about not being sure because it was 1, then it was 4... did you think I would say, oh actually yeah I am wrong and that other dude is right?

Best ResponseYou've already chosen the best response.0No you are being rude. So stop. You seem to be the one who can't move on. Like why are you still here? This is my question I politely ask you go away.
