MustangMatt96GT · November 8th, 2009, 10:28 PM

the second one is:

100 boards to maximise profit

and total profit

$57000

I will scan the sheet once I get the first one done.

MustangMatt96GT · November 8th, 2009, 10:35 PM

The first quesiton is 2000 x 1250 = 2500000

I will go scan the sheets.

Lefty · November 8th, 2009, 10:41 PM

Thanks man! Are you scanning the work; is that what you mean?

MustangMatt96GT · November 8th, 2009, 10:44 PM

yeah

Lefty · November 8th, 2009, 10:48 PM

Cool; thanks man

MustangMatt96GT · November 8th, 2009, 10:54 PM

The way you do it, is by using the Critical points of the function, by using the First Derivative test. the first function you have to make up, because all it gives you is a rectangle (LxW) and how many sub sections....

So you will see those in the pictures. you do the first derivative of the function, and then set it to zero. that will give you the CPs. then if the orginal function is not a straight line, you got to determine if its a max or min, by seeing if the values plugged into the orginal function before and after the CPs give you a positive or a negative.

The area one, is just a straight line so there is not a way to do that...

they are uploading now

Lefty · November 8th, 2009, 11:03 PM
