Aoron leaves one cify at noon. He has to be at another city 186 km away at 3:00 p.m, the speed limit the entire wAy is 65 km/h . Can he arrive At the second city on time? Explain
Derivative
I didn't realize I had to omit the y' and I got y(-2x + y)/ (y-x)^3
Derivative
Thank you!!!! i got it :)
Derivative
implicitly differentiate f(x) 2xy= y ^2 find second derivative with relevance to x and y. i get y''= -xy' - y/ (y-x)^2 this is wrong though. can someone please help me. thank you
Algebra I?
((x-3)/(x+1)) > 5 I get x < - 2 everytime I solve it, but apparently this is wrong. Can you please show me the steps? :/
Derivative
with respect to x f(cos x) if f'(x)= 1/x find (f(cos x))' i got tan x sec x this is wrong. please explain. thank you

Thanak you so much for your help, DrBob222

Oh, sorry. I meant to say that solution y has a 10 times higher OH- concentration compared to solution x. I hope it makes sense now. :-) Mary
