AQA A Level Maths Core 1 - 18th May 2016 [Exam Discussion]

Yeah i recall the line as y = -32x+40 that then leads to x = -5/4

And regarding another question about Q, the answer doesnt have to be (-5/4,0), as it only asks for x anyway so -5/4 is fine.

I didn't get that for b coordinate, I got something with -7 because c was the midpoint🙈🙈

Yes! the x-coordinate should be 12, resulting in B(12,-7)!

what did you guys get for the translation? (0.5 , - 41/4) ?

I got p as y=-32x -40 not sure if it's right though. ****ed that paper up big time.

I thought so too! There were lots of big numbers, and also some fractions, which is irritating

what did you guys get for the translation? (0.5 , - 41/4) ?

What equation did everyone get for the discriminant to work out k??

Here are some of the answers I remember getting and they're not in the right order so just let me know if any of these look familiar:

m = -1.5

B (-3, 4)

(3√5)^2 = 45, then part b was 75 - 32√5

y = x^2 - 7x + 2
= (x -3.5)^2 - 10.25

Translation through (0.5, 10.25) (idk how to get it in vector form on here)

k = -30 for something

(x-5)^2 + (y+2)^2 = 65, B(12, -7) (something like that, I can't remember tbh)

length CT = 9

integral = 5, area of trapezium = 63, shaded area = 58

R = 20, y = (x-2)(x - 3x -14) +20

I think the last question was something about a tangent and I got k = 4, k = 20

I got 7/4 for something in a question but idek what for

add anything else you remember please
