[M.Usman Khan]

was was the area of triangle in q23.plz tell me

A=1/2(AB)(32)sin0

 

[M.Usman Khan]

yup it was 480cm^2

 

[knight101]

what was the answer to the question where ken had $16 less den jane and the ratio was 5:3

 

[sjs]

it was 24 and 40

 

[knight101]

yeah...i got that too.

 

[sjs]

and what was the acceleration?
the gradient of the tangent....

 

[M.Usman Khan]

mine was 7.5

 

[knight101]

what will be the range of answerz for the accelaration..cos i got 8.0

 

[Jezla]

and what was the acceleration?
the gradient of the tangent....

Well... I got the tangent to be 0.76!

 

[sjs]

mine was 0.6667

 

[knight101]

oh sorry.. i meant 0.8

 

[M.Usman Khan]

what will be the range of answerz for the accelaration..cos i got 8.0

cant know the exact range till marking schemes come out but i think it should b btw 0.7 and 0.8

 

[sjs]

oh thank God!
u scared meee!

 

[sjs]

and the string question.....the lower bound thng...
it was 395 and 340?

 

[Jezla]

Yep you are correct!!

 

[knight101]

yup..as far as i know..

 

[sjs]

yayyy! =D
i'm so glad it went well!

 

[knight101]

where were we supposed to shade the area 4 dat last question

 

[sjs]

it was this little part outside the circle, inside the triangle and on the right of the perpendicular bisector...it was small triangularish part...

 

[M.Usman Khan]

correct
