bj sucks at math.

Yeah, so I have this handy corresponded course going on in front of me, and the first question has gotten me stuck for two hours. Two hours. I kid you not. But anyways, hopefully someone out there can help me.

It's about quadratic relations, and whatever, but yeah.. first question is telling me complete a table of values, and I don't know how to that. What equation I use, etc. And it's like.. ;________;

Help?

Lol, something called tutoring class?

There are no math tutors around me that I can afford.

I just need help with this certain question, and after this I'm sure I'll be fine on my own... kind of.

Okay I can try to help. Can you tell me EXACTLY what the problem is asking for? In other words, quote it.

Yeah, it depends on the question as their isn't a specific equation you use to complete a table.

What's the question?

Give a specific question, and maybe we can see what kinds of equations you're struggling with.

A gardener has 100m of fencing with which to enclose two square garden plots. The fences must not have a common side. To form each square fence, she cuts the fencing into two lengths.

[An image of one square, and then another square beside it that's about a quarter of the size.]

[a] Create a table showing the relationship between the perimeter of one plot and the total area of both square plots.

(This is from the math textbook itself. There's also another book which the lessons are all placed in.)

It gives me a table like this:



And then says to make a table of values out of it, which should (eventually) look something like this:



So I have to fill in the blanks.

It's telling me to create a spreadsheet on my graphing calculator if I am wanting to get these values. I understand how to use the calculator, but I don't understand what exactly I have to place in certain parts.

For each small perimeter "P1" from 1 meter to 50 meters:

Small area is given A1 = (P1/4)^2
Large perimeter is given P2 = 100-p
Large area is given A2 =([100-P1]/4)^2
Total Area is given A3 = A1 + A2 = (P1/4)^2 + ([100-P1]/4)^2

This is easy to implement on a TI-83 or similar. It gives charts in the style:

P   A1       P2    A2        A3
1   0.0625   99    612.5625  612.625
2   0.25     98    600.25    600.5 
3   0.5625   97    588.0625  588.625

and

P   AT
1   612.625
2   600.625
3   588.625
...
50  312.5
