Yup I hope so since I got that and subs x=10 in to get y=2 which is the centre

6 marks. It involved working our the grad and midpt that's why

I got x = (2+sqrt(44))/5

Posted from TSR Mobile

i got that too

Show the turning point, then state it's a minimum as its a positive parabola

Posted from TSR Mobile

So would I still get marks for explaining it, opposed algebraicly proving it?

I got q12 part i wrong, and I got the completing the square right, but at the end I added 12 instead of taking it away, so I got 3(x+2)^2+25 instead of 3(x+2)^2+1. How many marks do you guys reckon I lost?

Original post by pierre225

On the earlier question of (25/9)^-1/2 I only put 3/5 instead of + or -
I'll probably lose a mark won't I

crap i put that too, i hope they don't mark it down

For 12(i) I put 56/12 rather than 14/3, will I lose a mark because I forgot to simplify it?

maybe one, at least you didn't do what I did, I rushed it and got 56/12 to equal five :mad:

:mad:

(-2, 1) was definitely the minimum point, right? Not (-6, 1)? I took a gamble on that one... What did you all get for 'k' on the last question then?

yeah it was (-2,1)

Hi, I'm not sure why, but for the perpindicular bisector, I calculated the Tangent to the circle. I know I just don't see why I did that, that question was so easy :/

Would I get any method marks? Because The tangent was definitely correct as I checked it a few times...

Original post by Kira Yagami

How man marks was the perpendicular bisection question ? 5 ?

6 marks

What did you guys get for the proof question?

who is doing an unofficial mark scheme?!

What did you guys get for the proof question?

first one was arrow going right, second one was arrow going left i think
