That is also valid, and an excellent method too.For Q13 (a) (iii)
Instead of using the previous parts (or using SHM properties), was it fine to just let v^2 = b(x-3)(x-7) (since they said it was a parabola)
giving b = -11/4 ==> v^2 = -11/4 (x-3)(x-7)
v^2 = 11/4 (4 - (x-5)^2) and equating?
Assuming you get top end band 6s in everything else (96+), you can get an E3 in Ext 1 and still get 99+. 99.95 is a different story thoughGiven that I'm doing 4U in the 2016 HSC (I accelerated 2U and 3U), and I need an ATAR of 99+, what's the lowest scaled/adjusted result I can afford to have for 3U, assuming I get top-end B6s in all my subjects next year? (SDD, Ancient History, English Adv., Physics, 4U Maths) If a borderline or low-end E4 will stop me from getting my required ATAR I'm prepared to redo 3U. If it contributes anything, my expected raw in 2U is 98/99%. Idk if this is the right place to ask but gotta be in it to win it, right?
Tell me that story please xDAssuming you get top end band 6s in everything else (96+), you can get an E3 in Ext 1 and still get 99+. 99.95 is a different story though
Definitely not.for the limiting solution I wrote x -> 1 but I didn't say at the end x = 1. Is that going to cost me a mark?

No.Could the markers take off a mark for not sketching the circle in question 12 as it was stated:/
If everything else was correct, then no you would have not lost a mark. It is a 1 mark question only. Docking you for that categorises you in the same class as students who did not attempt the question, which is of course ridiculous.For 14c ii), will I lose a mark if I used 5C5 instead of 4C4?
