Both the solutions posted above get 16(a)(ii) wrong, I'm pretty sure

Alright, I'm going to go to sleep before I make any more mistakes. Best of luck for the rest of the HSC everyone!

You're quite right, it is C. I misread the question.

Nice, that's also good. Avoids having to use parallel lines (like I did in my solution) which are a bit tricky to give a reason for.

I think these are the answers to the MCQ. I thought they were kind of tricky for a 2U paper. Sorry, no working: B D B C A C D C A B

I would have probably skipped 14(c) if I was sitting the exam and come back to it at the end... it took me a lot of time to come up with that solution! And this is coming from someone who got 100% in his HSC for Maths Extension 1.

I'm going to let the tutoring centres do Q14 and before, but (c) is probably the hardest question in 14, so here's one possible solution: Triangle AFE is isosceles because AF = FE (regular hexagon). Angle sum of a hexagon = (n-2)180 = 4*180 = 720. Again, it's a regular hexagon so angle AFE =...

Here are my answers to question 15.

Yeah, you can also do the triangle thing, that's fine. Letting An = 0 should be fine. Not proving that 1+sqrt2 is a max will lose you at most 1 mark.

I'm a maths tutor. Here are my worked answers to Q16.

it's funny how unhelpful quotes about writing sound until you actually have to write 8000 words for your hsc (: i'm saturday, i'm writing dystopian short stories for my major work. school expects first draft done by the time i get back in term 1 so i have a lot of defeating self-doubt ahead of me

i'm saturday, doing ee2 as well. gotta get my short story/ies done this break. oh man.

hey, i'm saturday. i'm taking four units each of english and maths, and physics and visual arts for a total of twelve units. at the moment, i want to pursue a career in film, television, or radio.
