Edexcel GCSE higher tier Maths Paper 2 2H (1MA1) - 7th June 2023 [Exam Chat]

i got (4/25)^n but i doubt that it’s right

Going to do an unofficial mark scheme
Lmk if any of these are wrong or wrong order
1)Calculator skills beginning with 1.7??
2)reciprocal= 1.6 or 8/5
3)prime factor of 60= 2x2x3x5
4)Inequalities:
a=4,
b= drawn on number line
c= g> 25 (cant remember which way round?)
5)x=5/4 or 1.25
6)Cumulative frequency b) I think was 37 or 41?
7)Compound interest-Rachel had more money
8)Histograms=1.2 drawn and 120
9)Pythagoras and circumference,the circle with with rectangle in it answer was 40.2cm
10)iteration,
a= proof
b=1.669?
11) use some rule then take angle away from 180, I think 58.4°
12)algebraic fractions: x+2/2x-1
13)it was sine-1(9.25/12.65) pretty sure
14)simultaneous equations: y=-2 and x=1.5
15)168kgs
16)
17or might be 18?) can’t remember exactly but you had to find what a:c would be then what c:b would be then combine them then add them
18)?
19)quadratic sequence= n^2+3n-1
20)vectors: 3/5a + 2/5b
21)functions on graph drawn as:
a) y=f(x)-4, graph moves 4 down
b)y=f(-x), so reflection in y-axis
22)1-(4/5)^n - (1/5)^n
23)make the area of the small triangle =x. The other shapes are part of bigger similar triangles. The second highest triangle has side lengths 3 times of x. So side lengths 3x. So scale factor is 3, so scale factor for area is 9x. And to find the medium trapezium are you just do 9x-x=8x
Do the same for the largest similar triangle and you get 36x-8x-x=27x so it’s x:8x:27x which is in the scale factor 1:8:27
24)4(2+root2)a^2
