hmm what do you fancy at the moment? Accounting, finance economics and perhaps marketing are the orthodox choices. Accounting + finance with good grades usually gets you somewhere quite decent. Actuarial studies means alot of maths but seems like it has pretty good prospects too. Infosys is...

The most primitive way of doing things.. list all the possibilities methodically

9. C group the numbers according to remainders 10. A , use case bashing

there are 18 isomers.. maybe your teacher is not asking for all..

pretty much .. but you should put in a hollow circle there

there isn't a root there hmm for example " f(x) = 1/x" means f(x) = 1/x if x is not 0 and is undefined otherwise. so 1/f(x) = x for all non zero x's but is undefined at 0. compare with for example the function (x^2 -9)/(x+3)

this is not true.. you get an undefined point

CO2 is expected from burning petrol.. it's not that bad.. atleast it's not poisonous.

those are fine, but you should have 18 altogether.

have a look at http://en.wikipedia.org/wiki/Geometric_isomerism for example.. 1,2 dichloroethene would have 2 geometric isomers H Cl \ / C=C / \ Cl H Cl Cl \ / C=C / \ H H Notice how they are different. an optical isomer is harder to draw here... but...

so for example.. hypothetically, if all students in VA got 60 for VA but 100 for all other subjects they took, then VA's 60 will scale to 100.

strong preference. though I know ppl who go in earlier

no.. this is a classic situation. assuming you do better than him at school and the HSC then your school marks will be irrelevant. if the rankings are reveresed in the HSC then both of you will get the same mark.

pro bono?

It's better than my cousin... his parents compares him with his friends infront of him.

wrong.. obviously max = 8 at x = 3pi/4 you can do this one qithout much calculus.. you know that sine ranges from -1 to 1.. so max x is when that sine function takes a value of -1, so max x = 8

Find some good stocks then buy and hold... you need some dough and dedicate your time if you want to try anything mor sophisticated

1-2 to get a feel

How well a course scales depends on how it's students perform in other courses...

You might as well review prelim stuff than study year 12 stuff if you don't know it well enough
