Lagrange

OpenStudy (akshay_budhkar):

i am sorry i cant get this one. probably some 1 else will help you :)

OpenStudy (anonymous):

we can do this

OpenStudy (anonymous):

think we just have to think simple, not hard. put area of base as A and height as h and volume as \[Ah=500\]

OpenStudy (anonymous):

and therefore \[h=\frac{500}{A}\] now you know that \[A'=3\] and you want \[h'\] so we get \[h'=-\frac{500A'}{A^2}\]

OpenStudy (anonymous):

now plug in the numbers the sides are 18 so the area of the base is \[A=18^2=324\] and so we get \[h'=\frac{-500\times 3}{324^2}\] whatever that is

OpenStudy (anonymous):

course amberjordan could be long gone by now...

OpenStudy (anonymous):

oh hi. does this make sense?

OpenStudy (anonymous):

whatever you get when you compute that number i wrote for h'

well the problem is goofy, but i think the solution is correct
