1. (Original post by Ollie1999)
For the linear specification marked out of 70

1. £256.50
2. 750cm^3
3. 16cm
4a. 0.4 and 0.2
b. 200 150 100
c 0.125
5. 10cm
6a as average temperature goes up soup sales down
b 500
7. 22.5
8a 4 ( I got 2 )
b 1,2,3,4
9a w^2
b 12x^4y^5
c 6a^2b^4
10a 1.8 X 10^3
b 5 X 10^3
11. Enlarge 1/3 around (10,10) (I got -3)
12a 35
b 25
c A+D & B+C = 180
13a 12x^2+16x-3
b X=0.75 or -1
14. 1/6 cm
15 x= 5/y-3
16. X<7/9
17 a -2.7 or 2.7
b 9.6
18 36-16 root 3
19a y=1/X
b (0,1)
20. Substitute X as 2 and PI as 3 and both volumes are the same but PI is bigger 3.14 so the sphere volume would be bigger.

Not sure on 14, 16 and 17b but I think I got roughy 64
I'm pretty sure 18 was 9 - 4 root3
And 10a is 1.8 x 10^4

Was 14 the triangle q?? If so the answer is 8
3. I think I've done well apart from I must have misread question 3 and it put 48 not 16.... was it the inner rectangle? cos i did the outer and i must have misread it every time i checked it! Reckon i got about 65-67/70 though so yay!

^^^ yeah i agree with these
5. I did quite well I think, apart from the fact that I misread the direction of enlargement and thought it was the smaller shape being enlarged bigger, silly me!

You'll probably still get follow through marks though :P

I'm not too sure. I've spoke to a few people who think it said find 35% and others who thought it said increase. I thought it was increase by 35% but I'm not sure
Im 100% sure it was increase 190 by 35% :P

That's what I got but not sure

Brill I'm intrigued to find out what the grade bounderies will be like for this paper. Dispite it being rather difficult, i think a lot people would have done really well on it
9. How did everyone find the paper overall??

Me too, i made a bunch of stupid mistakes but hopefully i can scrape myself a C grade so i dont have to redo it next year :P

I made a few silly mistakes too but hoping to get an A* still. It is preferable as i am doing further maths next year. But i did think the test contained quite a few tricky questions
12. for 17b I have 2.25
I substituted square root of 5 into f(x) and then found the answer on the graph
13. it is 4.5
14. Im assuming this is for the Foundation paper?

It's the Higher Paper MysticKnight
16. hi has anybody seen one for foundation thanks
17. For 17b I used y=10 as you halved it, got 5 then you square rooted it to get root5 so you went along the Y=10 line and the root of 5 was around 2.2
18. Also what about the shaded rectangle question????

Yeah, here's a written solution if you're interested http://imgur.com/a/Bw6gY

I got something like that too. I think you're right. Can't remember if i put +9 or -9 but if you say -9 then that is probably what i put. Definitely remember putting those number though for that answer
I'm pretty sure I got 4-9 root 3, I think that's the answer, how did you find it in general?
