Q16 graphing

Look at the x^2 - 6x. The perfect square that produces an x^2 and a -6x is (x-3)^2 So (x-3)^2=x^2-6x+9 =====> x^2-6x+4=(x-3)^2-5 so a=3 and b=-5

There are four main restrictions on the domain. Look for them in this order: (1) Fractions: the denominator cannot equal 0. (2) Surds: the inside of the surd must be greater than or equal to 0. (3) Logs: the inside of the log must be greater than 0. (4) Inverse trig: for 3 unit kids only. If you...

I think as long as you know what each verb requires, as well as looking at the number of marks allocated, you should be able to ascertain how your answer should be structured to gain the marks :) but yeah the criteria can be quite strict.

look at this hahs circle jerk, our exams are essentially textbook questions + some easy past hsc questions

study and chill?

Applications before or on 30/9/15 incur a processing fee of $32. After this date the cost is above $150. If I submit my application now, and would want to change my preference in october (or after), will I be able to do so without incurring the $1xx fee?

Hey guys, I'm in year 12 and I've been looking at my options etc. I've narrowed my top preference to two options (at UNSW): (1) Actuarial studies/Commerce (thinking of a major in finance) - it sounds interesting. However I have read and heard of many different things about actuarial studies...

I've emailed on the 12 of August and have yet to see a reply

I'm leaning towards UNSW commerce or actuarial studies But my last preference is probably going to be some teaching degree

Re: Year 11 Mathematics 3 Unit Cambridge Question & Answer Thread The domain of y=\sqrt{x} (1-x) is x\leq 0 The intercepts are at x=0 and x=1 Expanding and then differentiating, the derivative function is y'=\frac{1}{2\sqrt{x}}-\frac{3}{2}\sqrt{x} (And kind of unnecessary here, but...

Hi, could someone please try the last part? I've basically given too much time to this question so it may just be that I missed something completely. The only thing I have done that might be of use after successfully completing parts i to iv was to prove that ZYOC was also cyclic. It's from the...

A general guide: You can rearrange the equations to get: 1+cos2x=2cos^2 x , 1-cos2x=2sin^2 x Most of the manipulations required will contain 1+cos2x and 1-cos2x and the identities above are almost always the required versions. For you question you could do two things: (1) Use...

Re: HSC 2015 3U Marathon Does this mean the question was only asking for the number of combinations but not the number of passwords that could be tried?

Re: HSC 2015 3U Marathon Hey guys, could someone please explain to me the solution to Carrotsticks' 2014 trial question? http://puu.sh/ijqqn/efd1be7108.png The solution is http://puu.sh/ijqnF/0c9662c363.png but there is no diagram. I can't get my head around it - I've only used the divider...
