Sorry I meant 224 not 226.225 for Q29.
Do you mind showing your working?

That's definitely a HD right thereNope, I might scrape a HD depending on the cut-off.
How did you go?Does anyone think I can scrape a D with my outcome?
If you get the first 20 questions or so right, you'll still get a D iircDoes anyone think I can scrape a D with my outcome?
LOL well he would do better than me, but from what he did I already pointed out some of the stuff he did wrong, which was at least 40 marks in total (including his own skipping of Qs)i think he would know how he went better than you lol
have some faith in your brother
although id be surprised if he ended up getting 100, maybe even 90 as wellinb4100
you go to sydney grammar??. he's not a mathematical prodigy. he's musically talented thoughHaha, doesn't he go to my school? I am sure he would've done fine for AMC, though it seems like 100 is pushing it. Unless of course he's a mathematical prodigy which I am told by you, he isn't.
I knew what a GP was but didn't get/understand the question anyways. So guessed it. Like I did for most of the test.lol I think I guessed 1/256
I wished they defined what a GP was, it shouldn't make much difference to the actual level of ability needed in the process to solve the question
oh well, I'm hoping for a distinction anyway
I think I talked to you at the study meat for a while. Mhm, you mentioned he was a music scholar.you go to sydney grammar??. he's not a mathematical prodigy. he's musically talented though
lol, all you had to do was apply the pythagorean theoremI knew what a GP was but didn't get/understand the question anyways. So guessed it. Like I did for most of the test.
Pretty much what I did. The idea of 'geometric progression' was made to throw off people although it isn't really that wordy.lol, all you had to do was apply the pythagorean theorem
Let the sides be 2, 2a, 2a^2
(2a^2)^2=(2a)^2+2^2
4a^4=4a^2+4
a^4-a^2-1=0
a^2=[1+sqrt(5)]/2
Hence, hypotenuse=2a^2=1+sqrt(5)
That's what I did too. This kind of question comes in schools too.lol, all you had to do was apply the pythagorean theorem
Let the sides be 2, 2a, 2a^2
(2a^2)^2=(2a)^2+2^2
4a^4=4a^2+4

Hence, hypotenuse=2a^2=1+sqrt(5)
Not really to throw off, that's just the term it's called when you do SnS. For people who haven't done the topic it looks weird but becomes quite customary after Year 11.Pretty much what I did. The idea of 'geometric progression' was made to throw off people although it isn't really that wordy.
What was the question?So what was the answer for the last few?
I got 6 for 29, although apparently it was 2. Any ideas?
What did you get? (with working plz)q29 was the terryfic list
and sorry to break any bubbles but q26 aint 200
Working out then.q29 was the terryfic list
and sorry to break any bubbles but q26 aint 200
Was the question 29 the same in the year 10 paper too?q29 was the terryfic list
and sorry to break any bubbles but q26 aint 200
