Pure Maths 12 today........

[elbeyon]

I did.. Area = Area of rectangle - Area of all three triangles. i got it like that. what did you do?

Yeah ! I guess that was the correct way of doing that.

 

[babycry]

the vector part 2 was a bit tricky as i equated 6k^2-10k+4 to 0 instead of 1 so ill prob get 2 out of 4, i spent like 15 minutes on that part and got nowhere but 1 comment on this thread made me realise i have to equate to 1 and the other people from my centre found the paper tricky so dont be surprised if the GT is like 56-58 for an A. (BTW this is from Zambia).

Could someone please reply me here? http://www.xtremepapers.com/community/threads/grade-threshold-for-chemistry-and-biology.20339/

1) a=2
2) x>=-3 , x>=1
3) area=975
4) k=-1 P(-2,1)
5) C(13,7)
6) y= 15, 75
7) angle=24.1
8) a=32 sum to infinty=128 , n=18
9) volume=9pie
10) c=1
11) 76.3 and perimeter 35.1

Those are the answers i remember

Can anyone upload the maths paper.

what did u guys get as the co-ordinates of c? you had to find the intersection of BC and AC right?

 

[Zuhair Rayyes]

How many of you proved the question with the area of the playground ? I guess it was 3. i). I forgot the question know but I guess we were supposed to show A = bla bla bla ! How did you got it ?

i think it was
A= x^2 - 30x + 1200
as for how to get it
A= 2400 - [(0.5)(40)x) + (0.50)(2x)(60-x) + (0.5)(40-2x)(60)]
if you need further explanation, id be glad to help

yes, AC would be the same as AX

 

[babycry]

yes, AC would be the same as AX

do u remember what the coordinates of c were?

 

[Zuhair Rayyes]

do u remember what the coordinates of c were?

I can agree with soccerprinc3's answer (above) of C being (13/7)

 

[shikha95]

I did l=a+(n-1)d < 360 degrees and got 179! :s

I got 18!

 

[shikha95]

No.. did part(ii) and found only lengths of OP and OR in the last one. You did?

Nope

i dno i mustve made a silly mistake.. cos i dint get that

 

[shikha95]

Hey is anyone taking GP on monday?

GP?

 

[Zuhair Rayyes]

i dno i mustve made a silly mistake.. cos i dint get that

I wasnt sure about it at first, but then i rememberd A(1,3) and X(4,4) and C falls exactly at that line

 

[elbeyon]

Does anyone knows what was the question of trigonometry's second part ? Was it cos2y = 3tan2y or some thing else ?

 

[Zuhair Rayyes]

Does anyone knows what was the question of trigonometry's second part ? Was it cos2y = 3tan2y or some thing else ?

i think it was cos^2(2y) = 3tan(2y) , although i still think there was a number before cos^2, maybe not

i got

(5,11) for C

 

[mhalvi]

1) a=2
2) x>=-3 , x>=1

4) k=-1 P(-2,1)

All your answers are correct but I can't remember 1 as the value of C,if I m not wrong it was the question where we had to find the eq through integration.I think c was 2 maybe

GP?

General paper!
