    For question 17b, i understand that the answer is 2.2 but how do you actually find it, i wrote 1.5 carelessly because i thought you go to 5 on the y axis, go across and then down which led me to 1.5. Does anyone know an actual method to find it?

    if that was the root5 question, you had to say that x was root5, so 2x^2 would be 10, and then you draw the line y=10 and see where it crossed the curve

    No problem, good luck with the exam on Thursday - remember it's calculator so you can do loads of trial and error until you get an answer that seems reasonable

    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. 4.5
    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 10^4
    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. 8 cm
    15 x= 5/y-3
    16. X<7/9
    17 a -2.7 or 2.7
    b 2.2
    18 9 - 4 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
    What are the topics roughly?
