Well, 2 unit Maths is assumed knowledge for 4 unit, so you need to have completed it (besides, it would be impossible to do 4 unit without having first done 2 unit). You just don't get examined on it in the HSC exams. I_F

I would simply plug the values into the calculator, since that bunch of questions doesn't say "don't use a calculator". That's the easiest way to do it. I_F

Chris is most likely to survive, followed by Albert, and Barry. In the duel, Albert (100%) would much rather shoot at Barry (80%) than Chris (50%), since Barry is much more likely to kill him than Chris. Likewise, Barry would much rather try and hit Albert first, since if he shoots at Chris...

Because: 1. They want a challenge 2. It's assumed knowledge or a prerequisite for a uni course 3. They'd fall asleep in General and it'd be a waste of time 4. All the class twats are in General (well, they are at my school anyway :p) I_F

Don't waste your time with Norton - in software terms, it's fat, useless, and slow. AVG is leaner, faster, and much, much cheaper (i.e. free). You can get it from http://free.grisoft.com/. Anyways, download and install it, update it, and scan your entire system and it's odds on you'll be free...

You don't automatically get 100% for 2 unit Maths if you do 4 unit. 2 unit disappears totally. I_F

Yes, it is a permanent solution (or it should be). Reinstalling basically writes over the operating system (and important registry files) while leaving everything else intact. System Restore is a bit more fiddly in how it works. Either way, you have nothing to lose. Alternatively, you can...

I rather stupidly added a zero in my calculations, so they were all wrong. I would have topped if not for that... :p I_F

Pay attention in the Supply and Demand topic. It comes back again and again in the HSC course. I_F

Out of 967 tests that recorded positive, 922 were actually correct. So the probability is 922/967, or about 95.4%. I_F

That's not true. The hottest Intel CPU has a total system power usage of 293 watts, not an individual CPU usage of 300 watts. Still, it draws 70 more watts than an equivalent Athlon 64 FX-60 system, so it's quite a lot of heat. I_F

Sulfur doesn't occur as a diatomic molecule, so in reactions it can be written as S. I_F

Chemistry Prac (Titration) - 12/15: rank 2. I now have 1.5 marks to recoup in the trial exam to get rank 1 back... :p I_F

C - sodium hydroxide is the strongest base here and would have the highest pH D would be my guess - all the other answers either raise the pH of the solution, or don't happen. I_F

Okey. For any particle moving in Simple Harmonic Motion (you must learn this formula): (x')2 = n2(a2 - x2), where a = amplitude and n = coefficient of t So: (x')2 = 36(4 - x2) x' = 6√(4 - x2) That should be right now. :) I_F

I'm not sure why you need help, because you've got the answer right there. Velocity is dx/dt, and dx/dt is the derivative of 2sin6t is 12cos6t. I_F

If there's only one sodium atom, the ratio must be 1:1 since sodium has a valency of 1. I_F

There's no magic solution. You simply have to do more work, and this is especially so if you only have 10 units. No one can wave a wand and make things happen. You have to put in the effort and make it happen. Best of luck, I_F

24/25 (rank 1) in our Physics prac on Motors and Generators. Still waiting to get Maths Ext. 1, Ext. 2, English, and Chemistry back. :( I_F
