1. is the unofficial mark scheme out

That they're parallel.
couldn't they have also been part of the same vector as well though as we didn't get the precise point of S
3. So what did people get for that table question. Where is had like x/4 or something cant even remember 2nd to last Q.
4. (Original post by sv42008)
lol no

that point S also satisfies the vector OT (?) so it is the intersection of the two lines.
I'm not sure, i wrote that they intersect but Im pretty sure I was wrong, others said it was parallel, so I just presumed they were right, my bad.

11 and x=6 and 2

I got 69 degrees, don't remember my working though.

And Pi is a number 3.14...

Is it's 25pi = 25*3.14, so you can't just take it away from 100, without first dealing with Pi. BIDMAS or whatever it's called.
could you not dsay 100- 25pie

I think i failed gg f me please tell me the 5 marker bout that girl i got right she didnt have enough did she? She had 3 she needed 4?

yes she need 4

It was direct proportion i think when y=k/x squared as y was directly proportional to the square of x. So you had to find the value of k and then substitute it in.

I did... before that post

yeah the constant was 100

ffs I knew direct proportion why did they put it like that.
13. (Original post by 34908seikj)

you've got the right answer 100-25pi
14. (Original post by Mahrez)
yeah the constant was 100
yeah, phew glad i got that one right
15. (Original post by candol)

No it asks for it simplified so it would be 25(4-pi) ...............
16. I made a few inaccuraceys but I am sure I got 90-94%
17. (Original post by 34908seikj)

Why is that simplified? That's factorised
18. (Original post by junayd1998)

It probably confused you as it wasn't put into words 'y is directly proportional...' as they just wrote x (proportional sign thingy) 1/x squared

But whether you expand a factorised form it is simplified

swear it is inversley proportional
