1. 1a. (and is probably allowed) Marks=3?
b. Marks=?

2a. Marks=?
b. Marks=?
c. Because the number of columns of B does not equal the number of rows of A Marks=1

3a. Since , choose any two factors, multiply those together, and write the other two factors: e.g Marks=?
b. Factorised, so is an arbitrary square e.g , and Marks=?

4. Marks=?

5. Marks=?

6. Marks=?

7. Marks=?

8. Marks=?

9. Marks=? www.desmos.com/calculator/um4a23ffwt .
Otherwise it is clear that , the first two sets being the integer solutions to the two inequalities

10. Marks=?

11a. Draw the thing. Marks=?
11b. Marks=?

12a. Marks=?
b. Marks=?

13. Marks=5?

14. , Marks=?

15. Marks=3?

16a. Marks=1
b. Marks=1
c. Marks=1

17a. Marks=?
c. The roots are and Marks=?
18. Marks=?

19a. . Marks=1 Think of 19a. and 19b. as transformations: https://www.desmos.com/calculator/4kphkki8vl
b. Marks=1
c. . This is rearranging of with Marks=2

20a. Angle at circumference is half angle at centre Marks=1
b. e.g Angle in triangle
Angle on straight line
Other base angle
Other angle in triangle Marks=5?
There are obviously many other ways to do this. I think we all know if we got or did not get marks on this question

21a. Marks=?
b. Marks=?
c. Normal equation
So intersects x-axis at
The rest is easy (show one length is twice the other) Marks=?

22. and were the pairs of solutions Marks=?

23. is the constant, because

Marks=4?

24. Marks=5

Not like anyone will ever read this with the official ms released, but I was one of 9 students in the country to get 100% marks in this GCSE.
2. (Original post by etothepiiplusone)
1a. 30
b. -1.5
2a. 13 -2
6 1
b. 11/8
c. Because number of columns of B does not equal rows of A
3a. e.g 3, 5, 91
b. Factorised ab-11b = b(a-11) so b is arbitrary square e.g 4, a=36
4. 2744
5. 4/5
6. 12.31
7. 16
8. 106.7
9. x=-2
10. 15.2
11b. -5 <= f(x) <= 7
12a. 3(5-x)(5+x)
b. 12n
13. 50a^2 / 3
14. a=4, b=10
15. y=(8x)/(w+1)
16a.3^(-2b)
b. 5^(x+2)
c. 2^(3m)
17a. (4, -25)
c. 5.79 and 1.21
18. (32/5) y^2
19a.k
b. -k
c. sqrt(1-k^2)
20a. Angle at circumference is half angle at centre
b. e.g Angle in triangle 90-x
Angle on straight line 90+x
Opposite angle in cyclic quadrilateral 90-x
Other base angle 90-x
Other angle in triangle 180-2(90-x) = 2x QED
21a. (0, 8)
b. -2x+2
c. Normal equation y=-1/2 x + 8
So intersects at (16, 0)
2*6 = 16-4
22. (-6/5, -7/5) and (2, 5)
23. -1
24. 3(2x-5)^2 - 70
"Because number of columns of B does not equal rows of A"... Wut?
3. How did you do the cos a question that was worth 2 marks
4. How much do you think 148 would be
5. (Original post by Shanpatel2000)
How much do you think 148 would be
Probably an A^, but at least an A*.
6. (Original post by Frankiitch)
How did you do the cos a question that was worth 2 marks
Square it so cos^2(a)= 1-sin^2(a)
Sina=k so Sin^2(a)=k^2
Thus cos^2(a)=1-k^2
Square Root it so cosa= root(1-k^2)
7. Because number of columns of B does not equal rows of A

^ For this question I put there are fewer columns in B than A. Mark or no mark?
8. Q1 difference between 20th and 8th terms = 20th term - 8th term = -30?
9. (Original post by _gcx)
Probably an A^, but at least an A*.
Hoping for A^; thanks
10. (Original post by LUSer21)
Q1 difference between 20th and 8th terms = 20th term - 8th term = -30?
Yeah but the values of the 20th term nd the 8th term were both negative numbers so you don't need to write -30 as a difference, just 30 is correct
11. Can someone describe question 9 and 10 for me since I forgot?
12. I got around 87 in this and 55 in the other.... is this an A*
13. (Original post by Mermaidqueen)
Yeah but the values of the 20th term nd the 8th term were both negative numbers so you don't need to write -30 as a difference, just 30 is correct
Will I still get the mark if I write -30?
14. What was the answer for the question where you had to work out the area of OAB i got 24 but I don't see it in the ms
15. (Original post by LUSer21)
Will I still get the mark if I write -30?
Im not sure, i don't remember how many marks it was but if it was out of 2 marks
you'd probably get one mark for calculating -30 and the second for writing 30
16. (Original post by Oliver_2001)
What was the answer for the question where you had to work out the area of OAB i got 24 but I don't see it in the ms
It was the area of OPB (which was 16) not OAB
17. (Original post by Oliver_2001)
What was the answer for the question where you had to work out the area of OAB i got 24 but I don't see it in the ms
What did u do for it? I don't remember my answer but what i did was:
calculate the coordinates of A and B, then found the distance AB
then i did 2/5 multiple by distance AB bc the ratio was 2;3 and the length we needed for the little triangle was the 2 part.
Anyways so i did 2/5 (distance AB) multiplied by 8 then divide by 2

Im not sure, i don't remember how many marks it was but if it was out of 2 marks

Idk, but I think the first mark is going to be substituting 20 and 9 into the nth term and the second mark is going to be the answer. So I think -30 will be in the accept column.
19. Could you put the marks in please?
20. what was the first question again?
