we derivate it then equal zero, that means w=\frac{10}{3^{2/3}} is that correct? Regards, |\pi\rangle

yes the picture is open and they never mention closed, and yes box

You will produce a jar with rectangular base and rectangular sides. aLL OF IT be manufactured in the same material. What size should the jar have on the cost of materials to be as small as possible? The length of the can should be 1.5 times the width. The jar should hold 1 liter. here we got a...

(a) f(x)-x^2 (b) I got no clue of that one

This is a problem from My book which I have hard understanding what they are asking for, I am pretty confused on the question would like to have help! Second derivate test works as follows: If f (c) = 0 and f'' (c)> 0 Then c is a local min point for function f (a) Show that c need not be a...

ok so we got 0.44106 degree/sec right? Regards, |\pi\rangle

yes i get that, but i have hard understanding what is the unit. I mean this is not degree is it m/s? or i am lost.. edit: if i get it correct then after 0 secund its that much in meter? Regards, |\pi\rangle

Yep i mean that. So if we derivate it we get this 37.5'/''(''('75.'+'1. t')''^'2 sqrt'('1-1406.25'/''('75.'+'1. t')''^'2')'')' - Wolfram|Alpha what do you mean after? Regards, |\pi\rangle

do you mean like this cos(x)=\frac{30+0.4t}{15} so i got x=\cos^{-1}(\frac{30+0.4t}{15}) Regards, |\pi\rangle

do you mean like 2 second later the hypotenuse is 30.8m and the bottom 15.8m did i get it correct? Regards, |\pi\rangle

You fly a kite. The dragon is 15m away from you (measured horizontally) and moves right now straight up. The rope is rolled out with the speed of 4 dm / s, and 30m is unwound. (a) Draw a clear picture of the situation, and explain what all introduced designations stand for. (b) What is the...

Thanks for the fast respond you are totally correct! I confused myself! Have a nice day! Regards, |\pi\rangle

Hello MHB, If I want to decide constant a and b so its continuous over the whole R for this piecewise function basicly what I got problem with is that x^{1/3} is not continuous for negative value so it will never be continuous for any value on constant a,b. I am missing something? or do they...

Haha! It Was a typo I see! I Was trying and trying, i Was like how can 3+s= 2+s Regards, |\pi\rangle

Yes! Have a nice day! Regards, |\pi\rangle
