1. (Original post by jn13)
in question 7 i copied out the equation wrong but did working out and everything, how many marks do you think i'd lose?
Every single one

Question Paper, courtesy of Nels98: http://www.thestudentroom.co.uk/show...819&p=55753987

1. (2 marks)

2.
Intersection with axes:
(0, 10), (-2.5, 0)
(5 marks)

3a. 1 (1 mark)

b. 0.6 (3 marks)

4. (3 marks)

5. (7/8,19/8) (4 marks)

6a. (3 marks)

b. (2 marks)

7. (4 marks)

8a. Use Pythagoras (2 marks)

b. (3 marks)

9a. False because rhombuses/kites can have diagonals intersecting at 90 degrees. Should be => (2 marks)

b. False; many examples where is an integer and is not, e.g. so , which isn't an integer. Should be <= (2 marks)

10a. Should hit x-axis at -3, 2 and 5, y-axis at 30 (3 marks)

b. Expand brackets (2 marks)

c. Translation 36 units downward (2 marks)

d. (5 marks)

11a. centre is (10,2), (2 marks)

b. A(-1, 0), B(21, 0), D(0, -3), E(0, 7) (4 marks)

b. (6 marks)

12a. (5 marks)

b. (5 marks)

c. (2 marks)

Enjoy!
Agree with all except question 1. Question states r > 0. Thus it should be +square root.

The square root sign already gives the positive root, you don't have to put the + sign.
4. hmm, ok. So i worked out that i think i may get between: 56-61. I forgot some answer and it also depends on how strict the mark scheme is. I need 82 ums. hmmm, i do hope.
5. how many marks did people get based on the mark scheme?

What if i put the answer>r. damn, thats that mark gone.
I might have put it equal first and below that done >r but i doubt it.
7. hey, on one if the questions where u had to find x in Surd form, i didn't simplify...would i loose marks? The question didnt say simplest form
8. For 10c. I put my answer as a column vector with 0 on top and -36 on the bottom. Is this correct?

What like this:

damn not even method marks ?? all i did was copy +1 instead of -1 :'(

What like this:

:/ yea... that was so stupid.

aye

Yeah, that's not right. Don't worry, everyone brain-farts occasionally.
13. do you loose a mark for not simplifying? even if the question doesnt say in simplest form?

I didn't simplify it because it didn't say to. I didn't want to lose marks simplifying in for no reason so no you wouldnt lose marks!

I did the same. I think so!
16. If I didn't simplify the coordinates down in question 5 and left them as x=14/16 and y=38/16 i'll still get the marks right?
17. (Original post by hajarjarir)

I don't think you do, there have been past exam questions where you don't lose marks for leaving it unsimplified. I think the rule of thumb is if it doesn't say "simplest form", you're alright (I could be wrong).

Enjoy, hope you all got what you wanted!
Thanks very much for that - I think I only may have dropped 4ish marks (fingers crossed).
19. What was question 6 again? I think I potentially lost two marks there, I can't remember the question xD think I lost maybe 3 marks overall but I don't know xD
