it was likely worth 1 or 2, not that many , doesnt require you to do much

The one about K and M and involved the remainder theorem .
Ok, so you could see that f(3) = 59 so x -

yeeeh it was much easier only on QS 6 i was stuck then i got it

DID u get K=12 M=-4

because other people got different answers..
That is correct.

This one is incomplete:

Long division of x-2 should give you an easy equation to factorise, (x-2)(x+5)(x+3)

(ii) Sketch the graph .

go through (0,-30)
Also go through (-5, 0), (-3, 0), (2, 0)

i know, but i thought they could get that from the previous answer

ok i don't mean to sound like a douche but i think q4 is still wrong. Shouldnt the final answer be -3/8

o ok thanks i was worried that it was worth 3, i know i had a mind blank on that one, dont know what happened haha, i estimate i got 67/72 hopefully, i reckon for an A it will be 57/58, who agrees?

iii) The graph of is translated by .
Show the equation of the translated graph may be written as

replace all x's with (x-1) and expand
I actually did it a different way. Can't remember how, but it worked too.

I'm so happy, I got all correct except from 11iv) and 6 (which i was so stupid about because I got the method correct, yet I put 2k+5=7k then 7k=29, then carried on to find m when k=29/7). Oh well, hopefully will get a good mark still x

it should i think ive done too much maths today had numerical methods as well :'(

in the mark scheme above, isnt question 4 wrong?
yeh part i) is
I deffo got something different

i think part iii) would have been 3 as more errors could occur. I think 58 is likely to be an A. ive looked at past ones and that seems to be about the average. 69/72 will likely be 100UMS

lol
19. Re: OCR MEI June 2010 C1
UMS is Unified Mark Score, or something. Most A levels are made up of 600 UMS, 300 in AS and 300 in A2. Every exam/coursework contributes a certain amount of UMS to each total, and so exams which are out of, say, 72, need to be scaled up or down depending on how much the exam counts towards the final UMS. In this case, 100
