Preet92 Posted May 8, 2011 Report Share Posted May 8, 2011 Is anyone else getting different ratios for point 4?I am getting different ratios for point 4 but I think it should be same because I am getting different just for two heights...for other heights m getting the same ratios Reply Link to post Share on other sites More sharing options...
saunders is god Posted May 11, 2011 Report Share Posted May 11, 2011 it should be the same Reply Link to post Share on other sites More sharing options...
nametaken Posted June 25, 2011 Report Share Posted June 25, 2011 (edited) Stupid question, but.....how would I go about finding the equation of the parabola?Just want to be certain.I've created my model with a 36m height, and I know how to get the maximum dimensions....but I'm just wondering about the parabola.Thanks.

nametaken Posted June 28, 2011 Report Share Posted June 28, 2011 Suggaplum: "As for the 2xy, try thinking along the lines of the shape of the rectangle " What does this mean?? Reply Link to post Share on other sites More sharing options...
ZiggyM Posted June 30, 2011 Report Share Posted June 30, 2011 ^ nametaken, this website might help explain that a littlehttp://mysite.verizon.net/bnapholtz/Math/extrema.htmlI think it's the second example/question that is relevant mainly?

ilanc93 Posted July 24, 2011 Report Share Posted July 24, 2011 Hey guys, do you need to prove that if you use the minimum room height it will be the most efficient or you just take it for granted? Reply Link to post Share on other sites More sharing options...
ZiggyM Posted July 25, 2011 Report Share Posted July 25, 2011 Room Height? What are you changing.. ? I'd say just keep it constant throughout your portfolio, I know in mine I explained the height I chose to say how it would include room for the infloor utilities and that kind of thing.It's a given value so I can't see why you would need to prove it.I'm assuming that's what you meant anyway.

ilanc93 Posted July 25, 2011 Report Share Posted July 25, 2011 Thanks for the reply. Yes it's what I mean. But the rubrics says the "minimum height" is 2.5m, which means that can be even higher. Anyway, I could just take it as a constant and say it's to maximize space, right? Reply Link to post Share on other sites More sharing options...
ZiggyM Posted July 25, 2011 Report Share Posted July 25, 2011 It's the minimum height because any smaller and you wouldn't be able to fit some people in there! Also with council regulations etc. However make sure you consider what having every floor as 2.5m means in regards to your actual model Anyway, to be able to compare all the different models you will need the floor height the same.

ilanc93 Posted July 25, 2011 Report Share Posted July 25, 2011 Yeah, it goes right where I was thinking. Thanks,really appreciated it PS: Translations are horrible! Reply Link to post Share on other sites More sharing options...
ZiggyM Posted July 25, 2011 Report Share Posted July 25, 2011 Translations of graphs or of languages? You shouldn't need to translate the 'model' for this.. assuming you are using a parabola? Reply Link to post Share on other sites More sharing options...
ilanc93 Posted July 25, 2011 Report Share Posted July 25, 2011 Languages of course hahaha, mine is in Spanish and the rubrics are not as clear as they are in English. Reply Link to post Share on other sites More sharing options...
A_B_D Posted August 21, 2011 Report Share Posted August 21, 2011 (edited) Hello guys,This is my first post. I have one question. Do we consider the parabola in the range of -36<x<36 or 0<x<72. Please help me with this question.Thank you so much for your reply... i have to submit it tomorrow.... Edited August 21, 2011 by A_B_D Reply Link to post Share on other sites More sharing options...

A_B_D Posted August 21, 2011 Report Share Posted August 21, 2011 (edited) Thanks Desi Glau. But when we use derivation, to find the maximum area in order to find maximum volume, the results are different. Which one did you use? the maximum volume of the cuboid which I found out was 149649.1898 m^3. Is this correct ? Please reply....thanks Edited August 21, 2011 by A_B_D Reply Link to post Share on other sites More sharing options...

Please reply....thanks you're welcome. no, the volume/area under the curve must be the same. my max volume is 149616 m^3. please quote me so I get a notification (i.e. so I can get back to you faster) otherwise I might miss your post 1 Reply Link to post Share on other sites More sharing options...
dessskris Posted August 21, 2011 Report Share Posted August 21, 2011 Thanks for the help. My equation is (-x^2/36)+36. Is this correct ? To find the area I will use derivation of 2x((-x^2/36)+36). Is this correct? Thanks yup they're both correct Reply Link to post Share on other sites More sharing options...

One last question, some guys told me that the dimensions of the cuboid are 25.5 x 50.8 x 150 and the volume is 194,310 . Which is correct, 194310 or 149649(which I found ). thank you...this is my last doubt..

Which is correct, 194310 or 149649(which I found ). thank you...this is my last doubt.. look, if you substitute y=25.5 to your function, the 2x will be 38.9 instead of 50.8, so that guy must have had a wrong model (or maybe he was talking about a different model with a different height) that's why. yours is just correct. believe me no problem, if you need any more help just let me know! 1 Reply Link to post Share on other sites More sharing options...
lavelaaa Posted August 26, 2011 Report Share Posted August 26, 2011 HI everybody,I am stuck at the last pointt, can someone help me find out he volume of the cuboids inside the structure.THanks Reply Link to post Share on other sites More sharing options...
