Also I came in at least 16 minutes late to my exam. My dad had to convince them to let me in to the General.

Yeah x=5 because QR was the smallest side so it couldn't be x=1

The Variation question was the one about depth of water in a tank?

Ahh yes, the d varies directly as blah blah..., I got 40cm

Did you all get x=5 for the last question in paper 2?

yes

[anthonyfl]

(Original post by humza100)
was 6a the surd one, if it was it got 2 root 11

I got that too, I meant the one about "find the equation of the axis of symmetry" and also the one with indices where you had to solve for n.

Me too!

YASS! I wrote a little paragraph where I went off on a tangent () explaining why x couldn't be 1. Time well spent haha...

[regalrose]

Woah my friend lectured to me about why the depth should be 37... I feel good for having 40 now

No I got that one, I'm talking about the (2)^n = 1/64 one, something like that?

I got n= -2, cos the first answer was 64, and I thought if it was a negative power you put 1 over it, therefore getting 1/64...?

Oh I got -2 for n!

It's definitely 40cm!

[regalrose]

That is what I got too and my teacher said it was correct. (n=-2)

Also (n/2)x(n/2+1) for the second last one. The last one I got 2550 = 50x51

Yeah, the formula was 1/2n(1/2n+1) I put...?

[regalrose]

Yep!!

Yep!!

I feel much better about paper 1 now after seeing people's answers on here, except about a few questions I know I got wrong

Btw did anyone get 3.03 million vehicles or something for one of the first questions?

So was the question:

, find the value for n?

If so, it'd be -6. But I get the feeling that's not what it asked.

Hey can anyone upload the paper? I'd be happy to solve and post the solutions?
