AQA Maths Pure Core 1 MPC1 Jan 13th 2012

Yeah I think the best now is to beg my teacher to tell me the answers somewhere next week.
>.< But anyway I hope everyone did allright.

Did people get 11.5 or 92/8 for 1.c?

Now that I think about it, I think I got

92/8

, and I simply couldn't be bothered to try and work it out. :P

I am not sure. I think it was 92 over something. Not sure if it was 8 or 11. >.<

I got 11.5 for 1.c
8 for integral, 8-2 = 6 for part b
for the area i got -12 < x < 8
then put the next bit wrong because it should of been 5.5 < x < 8 i put equals to, only one mark though
I forgot to put dy/dx=0 for the show that this value is minimum
and i got -14 and 37 for the simultaneous equations thing (AQA)
I thought this was a hard paper, wanted over 90% but unsure as of now..

Ohh good, I was like wtf? because I was expecting a nice number like always -.-

Reply 27

yeah I'm in upper sixth and I was thinking that a lot of people will think that it would have to be an integer in the fraction.
i got 3 - root10 for the surds question, taking an educated guess and my maths teacher said thats what he got so yay :smile:

Have to say they made this paper quite challenging

I had no idea what to do for the p(x) question-it was unfair aswell because I didn't understand the starting parts I just could not do the other bits-Darn AQA!

Got 8 for the integral and
6 for the area - tri

What did people get for the (x-3)^2-14 add the vector (3 -4) question?
I got (x+1)^2-(17 I think)

Reply 29

for the vector question I got (x+1)^2 - 14. The vector was (-3,2).
And for question 1.c and 1.d I got c=-92/11 and k=92/8 (I think not 100% sure)

I got and my teacher confirmed correct (x+1)^2 - 14
just added the 3 to the (x-2)^2 to get one, added the 2 to the -16 to get -14 and then put it back into the first equation to check and got the same thing

I think I messed up the vector translation >.< I translated as if it was starting on x^2 = 0 and wrote (x+3)^2 + 2 when It asked to translate from the given equation. FML

Reply 32

And damn for the inequality question my final answer was 6 and 7 and not 5.5<x<8.
Omg even thou I thought about it correctly Im going to lose the 3 marks so stupdly.
Argh >.<

Really? The integration gave me really nice numbers. Oh damn, this is going bad >.<
My shaded area was 6. 8-2(Area of triangle). >.<
What was the value of k for the first page last exercice?
I think mine was k=-92/11.
Oh confusion! >.<

your answer for the area was correct, but for k i got something like 23/2? :frown:

**** aqa.

Reply 34

well I dont know anymore. I think my k was 92/8 now that I think but I am not so sure anymore.
Awwww what a disappointment.

Reply 35

i also got 23/2 or 11.5.
i did y2-y1/x2-x1 =8/11
0-4/k-6 = 8/11
-4 if -1/2 of 8, so k-6= -1/2 of 11, k-6=5.5, k=11.5? thats what i thought anyway

Reply 36

Yeah well k=92/8=46/4=23/2 :P
We are both correct but they might take one mark because I didn't simplify it properly.

Reply 37

Yeah that's right, I got 92/8 which is 11.5 but don't think you had to simplify it.
