I havent done this shit for like 15 years, can someone refresh my memory?
4e^(-.10469x0.5) + 4e^(-.10536x1) + 104e^(-Rx1.5) = 96
answer is .10681
For the life of me I can't remember how to do this shit.
Bah fixed a slight typo
-
You sure those numbers are right? I keep getting .0899 but i'm probably doing something wrong.
-
That shit is way over my head. Fuck that
-
lol, haven't done that shit in ... 7 years
Goddamn I need to get back to school.
-
Math is hard, let's go get icecream.
-
just remember that e is a constant, like 2.71 or something close to it, are you supposed to solve for R?
write the problem properly and get back.
-
also remember that 'x' does not mean 'multiply' use the fucking asterisk to show multiplication '*'
is this the problem?
4*e^(-.10469*0.5) + 4*e^(-1.10536*1) + 104*e^(-R*1.5) = 96
solve for R?
i get R = .0899033
-
Assuming "x" is multiply, and "R" is your variable, I get 0.0277719.
-
FML this shit.
-
You mistyped the problem, it should read.
4*e^(-.10469*0.5) + 4*e^(-1.10536*0.1) + 104*e^(-R*1.5) = 96
answer is .1066694
-
That makes sense now. I thought it was weird that he put the *1 in there.

GraphCalc, fuck it.

FML this shit.
Write the fucking question correctly you dumb fuck and someone on here will help you. Not to mention, you didn't say if you needed to show work, solve by hand, or what. Otherwise, you punch the numbers into your damn graphic calculator and you can easily get a result. Even on a TI83, you'd just set the problem up where X=R and Y=the equation. Then find the 0 on the graph. It would take 1 minute in total if you decided to jerk off for the first 50 seconds.

that shit is just level 1 algebra
-
Fixed a typo, its -.10536 not 1.1....
Pat can u show work?
-
turn on TI89
press home button
press F2, and select nSolve
Enter equation exactly as shown, using x as your variable. After entering the equation, type ,x)
Press enter

anything other is a waste of time

He might be required to do a large portion by hand. If he is asked to isolate the variable, he will have to change the e's into Logs. I don't disagree it is a waste of time, but it might be what is required.
