NSW 2007-08 Budget relavent to Economics?

Hey,

Since my original maths question has been answered quickly by 3 geniuses, I might as well convert this thread to about Economics to save myself from opeing a second thread.

Well, I watched the news today and saw something about NSW Budget, surplus, increased investment in schools and infrastructure etc and I am kinda interested in reading the whole thing. Anyone know where I can find it and whether analyzing budgets are part of the Economics course?

Thanks

Yeah, care to explain?

use graphical method

I tried doing that, wasn't right. Infact, does the HSC force you to use certain methods for maths?

Why not just use the distance formula twice, once you've got the co-ordinates of P?

Distance AP = sqrt(20),
Distance PB = sqrt(5)

Which is a ratio of APB = 2:1

I'm in a rush so I quickly did what was in my head. I didn't use the division of interval ratios so you'll need someone else to explain.

You A(1,3), P(3,7) and B(4,9).

Use distance formula
