GUYS DID YOU TOOK TANGENT FROM "16s''

answer plz

 

[Angraiz]

Yeah, what did you get?

And there was a curve. Gradient of distance time graph = speed. The speed was increasing first, so the gradient shouldv'e been increasing, then became constant(straight line)

answer plz

No we had to take the tangent at 18s as was stated in the question

 

[XPF MASTER]

100% accurate tangent gradient ------> 0.75 (they might consider the answer correct if it is in the range 0.7--0.8)
what was answer to the PERIMETER of SECTOR??? i know but what did you guys write?

 

[book worm]

perimeter= r(pi + 6)/3

 

[XPF MASTER]

ya i know thats the sector but did any1 add the radius??
becoz for the cmplete sector radii had to be included

 

[book worm]

the radius was to be added. what I gave was the simplified answer.

Perimeter= 60/360 * pi*r^2 + 2r

 

[emkay]

i messed it up, Paper1 was average gotta do better in paper2!

 

[XPF MASTER]

hmm gud i didnt do it

 

[Sijan92]

yaap u need to multiply the radius with 2 then add it with the arc length.

 

[AlteredTuning]

can anybody tell me the answers of the simultaneous equations??? i got something like y=4 and x=29 (or 24, dont remember exactly)...

 

[allthatglitters16]

Till now all answers correct: )))yay!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
@all
Good luck for paper 2

 

[beststriker]

mine were x=5 and y= -4......

 

[allthatglitters16]

i dont think so.. plz tell me the qeuestion

 

[allthatglitters16]

i certainly got a negative or i just dont remember

 

[beststriker]

majority get this answer.........check other maths discussion topic....

x=5 ,, y = -4

 

[emkay]

i got the same, x=5 , y = -4

 

[Mobeen]

yea .. radii was to be added .. other wise ull get no marks ...

 

[miracle]

how many marks did enlargement carried?
