Any one attempted the graphs qs???

 

[Dark Destination]

Lol no. Relax. :v

40.5 should be the right answer.

 

[Ram97]

40.5 should be the right answer.

Ab bas bhi kardo

40.5 should be the right answer.

Yes you are right, 40 people and half a body

 

[Laibaaa]

What were the ratios? 1:4 and 1:3 ? Vectors question

 

[Ram97]

Minimum length kia thi???

Not 1:3 but 1:15

 

[Ram97]

28.

When area is 100 tou what was length and width and us say pehlay part main length and width kia thi???

Did anyone use the grid for vectors...
Wht did u guys wirte in Sec B circles question abt two lines being paralle..I know 1 mark wud be given for proving similarity or congruency but tht second mark I think was for recognizing tht 2 diameters tht is 2 STRAIGHT lines make trianlges...They form VERTICALLY OPPOSITE ANGLES and hence the two opposite sides wud be parallel.I think proving similarity or congruency was not enough coz we cu have a similar triangle slightly tilted..Either we needed to mention abt vert opposite angle or equivalent tht diameters.....strt lines......opposite sides and like tht..Tht,s wht I think...Ps I used 3 lines for the explanation ...

 

[muhammadali233]

I left both.

de tali hi5 me too

 

[Ram97]

I left both.

WOW!!

 

[M.Omar]

I left both.

Which question?

Eqn. kia thi??? and what was vector CD??

 

[muhammadali233]

They were pretty easy actually. Just didn't have the time - 1 min. What I was doing was entering random values into calculator and hoping they fit the formula.

A5 and A6 was quite long wasted 30 min and after finishing section i only had 45 min left which pissed me off

 

[M.Omar]

Eqn. kia thi??? and what was vector CD??

for the vecotrs:y=-5/4x +7 .CD sorry I don't remebr the exact question of tht or wht was CD? :/

 

[M.Omar]

Vector CD was 5b - 5a.

Acha it is this question....Well since u got a scale factor of 5 which I don't quite understand how I mean AC=AB +BC=b+4a-b =4a so scale factor shud be 4 ...Khair another discussion
Then yeah CD =4(b-a) dep on scale factor
And wht was the area question and minimum length wala question was it the graph question or like tht

 

[Dark Destination]

Vector CD was 5b - 5a.

Your entire Vector question is WRONG! ZERO.

It was 4b - 4a

Just so u know .Aj shield ki maar khanay ki baray..I mean it,s a see saw battle every week...One week the shield is on and the other evolution

 

[muhammadali233]

This is gonna happen to me
