Okay even though I dont know much ext 2 stuff I can see this paper appears much easier than some others ive seen.

16 B and C.... ahh well, everything else was easyy

 

[SandyS1995]

B was ok, you had to draw a line from T

 

[RishBonjour]

fuarr. it was an okay test. left out 16 c, part II
the one with show c> 1/2 or something. Instead checked my question 1 and found 2 mistakes. I think my paper has silly mistakes all over D:

 

[nicholash747]

How were you supposed to do b and c? The rest of the paper was easy I just couldn't get those two!

 

[hsc2012la]

Could someone explain how to do C i?

 

[cookeemonstah]

simultaneous equations

farkrkrkkrrk I was looking at a state ranking till i lost 3 marks in question 16. FFFFFFFFFFFFFFFFF

state rank fro 2u is a solid 100.
you will still get around 99 HSC mark.

 

[scarvesss]

b was fine, c took the dick

 

[Rawf]

16b and c were terrible....
I only got 16b (iv) and the rest i was like.. wtfffffff. I thought i was going to get (iii) but apparently not -___-
For 16c, wth shit son this made absolutely no sense to me lmaooo. I got c>1/4 for (ii) cause I tried doing discriminant but I had no idea what to do for (i)

What did you guys get for 16a (ii)? i'm not sure if i did it right or not...

i got all of q16 apart from cii. i reckon the paper mighta been wrong because i rearranged to find r, and made r>0 as the question said, and i got c>1/4 not c>1/2. did anyone get the right answer?? if so how??

I did the same thing!! I don't know if i did Ci, the correct way though. Could you explain what you did?

Haha this!! I managed to get C (ii) but I just could not work out (i) :O
Didn't get time to look over everything because I spent so long on 16, but provided no stupid mistakes like I usually do, the rest was all pretty good

for ci i used simultaneous equations with the two curves because they could both be rearranged to be in terms of xsquared and then just simplified. but ii i dont know how it couldve been >1/2
