i'm not getting 4(ci)

plzzzzzzzzzz tell me hw to solve!!!!!!!!!!!

can you upload the mark scheme for this paper?

 

[Igcse stuff]

guys how do you find the rotation in transformation when the center of rotation has been changed?
e.g
if lets say it has been changed to (2,2) do you replace the 1's in the transformation matrix with 2's ?

3.d.ii) 1 - 0.67(Damon finds 2 stop signals)
=>0.33
4.d) u need d graph fr it dude
e)u need 2 draw a tangent...wats so tough in dat part

I dont know how to do the tangent part
Nor the graph part

Hi I'd just like to know if anyone has the maths summer 2012 past paper markschemes/examiner report/grade threshold (if those last two are available yet?) the codes I'm looking for should be something like this: 0580_s12_ms_43 (this one specifically), 0580_s12_er, 0580_s12_gt.
I really need these (at least the first one) before the end of the week, so any help as soon as possible would really be appreciated Thanks

Thank you very much!

Can anyone tell me the vertices of the image G with an explanation? In the marking scheme the vertices weren't given.

Thank you in advance.

Well, em not sure..But it implies that is strecth-y axis invariant.So well, when I tried, I got (6 1) (2 1) (4 4).Im nt 100% sure.

Salaam.

Thank you. I actually forgot what the matrix was for and I googled it.
This is the first link which i checked: http://www.mathamazement.com/Lesson...nants/coordinate-transformation-matrices.html
It said along the x-axis which probably meant that the invariant line was y-axis. That would have confused me.

Thanks again.

so here are the answers:
Q10a. rhombus
b.kite
c.2x, 180-2x
c. 120
d.13 (but I don't know how to get there

May/June 2004 {Paper 4 ,0580}
Q-3 (c)
Q-6 (C)
Q-9 (e) and (f)
only

So in Q3c, u have to find the frequency density. U do: number of days/ difference in interval. So for 0<d<20 u would do 58/(20-0) which is 2.9. For 40<d<70 u would do: 147/(70-40)=4.9
For 6c: you have to find the total surface area of the solid. Then, do cost of covering solid/surf area. So the total surface area is part b (324.7)+ 2*3.141*7^2. The total surface area is 632.6. So to answer the Q u do 411.58/632.6=0.65
For 9e: u draw a kind in Ur graph where x=70 the find the higher possible value of y Which Is 38
Hope i helped!
Btw, have u done all past papers since 2003 or 2004?
