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
So what did people get for that table question. Where is had like x/4 or something cant even remember 2nd to last Q.
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?

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.

you've got the right answer 100-25pi

yeah, phew glad i got that one right :smile:

No it asks for it simplified so it would be 25(4-pi) ...............
I made a few inaccuraceys but I am sure I got 90-94%

Why is that simplified? That's factorised

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
