for MC 18 i think the answer is D cause the question says letters and numbers may be 'Repeated'
M must be first
But the other option are

26 x 10 x 10 x 26 x 26
=
26^3 x 10^2 (A)

it said that M was already at the begining. so i think that takes off a power.
yepp you're right. that other person is WRONG WRONG WRONG.. yep because M is already at the front.. so you x it by 1x28... etc etc etc...

Op, can you post the paper up?
Sorry, I don't have a scanner and I lost the paper in the morning that I got.

I got the paper because I was reading the paper for HSC student at my school.

I am sure I got everything correct there but you really cannot rely on my answers.

Nah I'm pretty sure they're right cos I've gone through all the MC and I'm fairly sure that's them

Oh except 15
I think it's
(320 x 12 x 5) - 16000
= A (I think)

If you wish to find the smallest angle, the smallest angle is always opposite to the smallest side as in Q5.

Cos rule stated otherwise

But it depends on where you used your cos rule.

You apply the cos rule to the angle where the opposite side is the shortest.

I am pretty certain about this seeing that I have done the similar questions from my 2 unit HSC questions.

AAM is wrong.

you got question 3 wrong.... the answer was 4 not 24, because it was asking for the specific digit of "n" not the range

and i think my question 1 was different from yours.... wasn't sure about that one though
ahhh no dude he was right...as you can clearly see he wrote...

[3 A stem-and-leaf plat question, my answer is 24 which means it is 4. ]
