Ahh okay awesome. Thanks.

Okay so, if I take on 11 units for my HSC with these subjects: Standard English 2 Biology 2 Chemistry 2 Senior Science 2 Mathematics 2 Extension 1 Mathematics 1 Say I do great in Ext 1. If they take your best 10 units, how does that work? S:

Haha, doubt it, I would know if we were in the same class =P I understand now how to do these types of questions, if I have more questions I will be back. Thank you for all the help.

I am quite confused about these questions, and don't know how to go about doing them. Help would be appreciated (: 1. $If$ f(x)=5x-x^2, $find$ f(x+h)-f(x). 2. $Given $f(x)=x^2+4x-5, $ find $ f(x+h)-f(x) $ and also $ \frac {f(x+h)-f(x)}{h}. 3. $If $h(x)=10^x+10^-x$, show that $ h(2x)=[h(x)]^2-2

All the questions I've posted are the ones I need help with.

So I got a quiz recently, and I had almost no clue with some questions on what to do and how the answer was such. Help would be appreciated. Step by step, if possible >.< $1.Simplify: {\frac{2}{x^2-9}}-{\frac{1}{x-3}}-{\frac{4}{x+3} $2.Solve simultaneously for x: 3x-7\leq 2x-3\leq 5+x...

When we were learning this, my teacher used the key words " as far as you're concerned;" Although in a sample of air, pollution and such will not be 100% uniformly mixed, but the naked eye cannot see down to that molecular level. Therefore one can call it homogeneos. If you could see a...

First day today, turned out to be a nice day I suppose. Got our timetables and diaries first period, and the whole "year advisor" and "principle" and "deputy principle" and "pretty much everyone in the whole fkin school" came and gave us their... interesting... lecture. Homework on the first...

Thank you for the fast replies. I guess I understand the process of it now. So I'm thinking this UMAT is sat for at the end of the year? And who are the people interviewing you?

I will be doing my preliminary course in 2010 (NSW), and I was considering a career in medicine. My goal is to work in a hospital as a doctor(Physician?), the ones who do check-ups and stuff (My english sounds real bad here, but I just don't know what they are called! I looked it up and got...

The watch tower question?How there's point A and B, and they can only see up to a certain distance (6cm in drawing) and yeah. That question was a breeze. The only thing I actually left out was the equation of the cube, last question of the paper. Anyone know the answer?

Nope S: Trials week is over~ All in all, it wasn't as terrifying as I expected it to be. And since the actual SC is much easier, I supposed year 10 is a breeze~

Woo dam. Is it true the trials are easier than the actual SC? I have my Maths and History/Geography tomorrow TT Maths History should be a breeze but I'm horrible with Geo.
