AQA A Level Mathematics Paper 1 (7357/1) - 6th June 2023 [Exam Chat]

Last question. Is it 8 minutes or I’m terribly wrong

Did you get some stupid fractions for x and y value for centre of circle?

(5,8)

Did you get some stupid fractions for x and y value for centre of circle?

I got 8 minutes, anyone else?

Yep, 8 minutes

Last question a and b were both 1/8 right

Last question a and b were both 1/8 right

Last question a and b were both 1/8 right

Answers I got :

288cm for min distance
Equation of circle : (x-5)^2 + (y-8)^2 = 170
Number of intersection = 4
Exact value of cos b = (2root10)/7
Trapezium rule 2.3336 or smth like that
Value for L 350
Number of minutes for container to be full - I got 8.1 minutes so I rounded to 9 for it to be actually full, since 8 minutes wouldn't mean the container is full? But I might be wrong there
Exact area for 2^x I got 15/(16ln2)
Value for R root 17 and alpha as 1.33
Value for p was 4/5
A and B were both 1/8


I'll edit if I remember more

Coordinates of stat points (0,0) (4,2) I think (may got numbers wrong way round)


I'll edit if I remember more

anyone got K is 15/32 for the sum questions?

cosb = -(2root10)/7?

I agree with all of these but I put 8 minutes after a lengthy debate in my head over whether to put 8 or 9.
