Since we are doing inb4's now inb4paradoxicacomesfirst (btw im full srs, I have a feeling paradoxica is going to come first)

Re: HSC 2015 4U Marathon That is how I initially proved it, but I felt more comfortable using the AM-GM inequality

Re: HSC 2015 4U Marathon Rearranging the inequality will reduce down: ab \leq \frac{1}{4} In order to prove it is true: $ Assume: $ x+y \geq2\sqrt{xy} $ (And substituting x and y for a and b) $ \Rightarrow \frac{1}{2} \geq \sqrt{ab} \Rightarrow \frac{1}{4} \geq ab So knowing that ab...

Re: HSC 2015 4U Marathon Just out of curiosity, when making the substitution x=1/k, would we need to state conditions for k in order for the inequality to exist? For example, in this question, would we need to state k \geq 1

Re: HSC 2015 4U Marathon After that all I did was: $ Let $ x=\frac{1}{k} \therefore \frac{1}{k} \geq \ln{\left(1+\frac{1}{k}\right)} \Rightarrow \frac{1}{k} \geq \ln{(1+k)} - \ln{(k)} And you sum both sides to get: \sum_{k=1}^{n} \frac{1}{k} \geq \ln{(n+1)} - \ln{(1)} Which...

It could be tonight, or it could be tomorrow night.

Tradingeconomics.com Has everything there

Was I the only one that got reminded of MI5:Rogue Nation, after reading this?

re: HSC Chemistry Marathon Archive Solids and liquids. Don't forget about the liquids, as they are not counted in the K constant as well.

I just read this paragraph from Dixon on page 188: The concept of the NAIRU has important implications for economic policy. It suggests that policies to encourage economic growth and reduce unemployment will be worthwhile up to a point, but beyond that, these policies will only create...

Tfw you realise that forgot to say "refer to stimulus" for section 3. I used the stats, and I barely quoted the quote. *sigh* too late to do anything about it now

Thanks for confirming my suspicions

I said differing level of expenditure on factors of HDI, for example on healthcare and education, and also said differing levels of technology advancements, and capital formation and explained the digital divide.

If there is an increase in headline inflation, and a decrease in underlying inflation, then it indicates that some volatile good has increased in price which can be due to a rapid decrease in supply. So C and D are auto eliminated, as A and B show the rapid decrease in the supply of a good. A is...

Raw mark last year was 95.
