Maths 2012 Paper 22

[sanchit]

What did you guys get for the shear matrix? The shear factor was 2. but the matrix i got was like

(1 3).
(0 2)

I got this by Multiplying the Original triangle Cordinates with (a b).
(c d)

So it was like- (2 3) * (a b)= (4 5)
(1 1) (c d) (1 1)

Am i correct? And also for the first quuestion the TRINGNOMETRY one, what was the answer for exatcly 2 lines of symmetry? and the one with Y varies directly as the ^2 of (x-3) what was the constant? i got 0.25.

Assalam-o-alaikum wr wb...
well..the shear factor was 2
and the 2nd part was

for second question...the first part was 'I' and the second one was 'I' and 'N'
i think yeah...it was 0.25..what was the final answer? may be i remember it after that

I got 196.

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

A
I got 196.

yeah...that's right

 

[sanchit]

yeah...that's right

But are you sure the K is 0.25? cause the answer only carries 1 marks, the rest is K and working. Some people got K as 4. The answer was same But the K was diff. My formula was (x-3)^2 = ky

 

[khan-12]

which question was this 1 the parallel line one

well...that's for sure, the answer wasn't 4...i don't remember exactly but it was '0.' something!

 

[khan-12]

the one in which we have to find k and then y was k=4

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

the one in which we have to find k and then y was k=4

well...in that k wasn't 4...it was 2.5

 

[khan-12]

well...that's for sure, the answer wasn't 4...i don't remember exactly but it was '0.' something!

parallel line question k was 2.5

 

[sanchit]

I think it was 0.25

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

parallel line question k was 2.5

yeahp..

 

[khan-12]

well...in that k wasn't 4...it was 2.5

i am tellling about the other 1 in which we have to find k
y=k(x)squre

 

[khan-12]

I think it was 0.25

it cant be because if u see both line were parallel so the value of c was given for both lines and c was half of the other c e.g c=10 in the line given with gradient and other was 5 and y=8 other was y=4 so its half the gradient given was 5 so it will be 2.5

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

i am tellling about the other 1 in which we have to find k
y=k(x)squre

there were 2 k's....which one you talking about? the parallel line one or the direct proportion one?
though...none of them was 4!

 

[sanchit]

Im talking about direct propotion one

 

[Lilpumpkin]

parallel line question k was 2.5

what about the other one?

 

[svenas]

parallel line question k was 2.5

help me in this question
0580: 2009 o/n q8 last part, plz explain it to me..
