sorry to say man but i think so u r wrong in the first question (AB)
well AB=OB - OA either AB = AO+OB The answer should probably be (3,5) plzz check it

yah it is--cuz the magnitude has (3,5) that was a mistake--thanks bro

A question which I faced today in June 2012 examination
it says:
The population of india increased by 20% from 1989 to 1999
The population of india further increased by 17% from 1999 to 2009
Find the increase in india population from 1989 to 2009

is that maths B paper 1?

 

[mahmoud631]

no math A

 

[poizoned black]

no math A

THANK GOD!!!!
I THOUGHT I HAD MISSED A QUESTION LOL!!!

 

[mahmoud631]

no you didn't, but can you solve this one xD

 

[poizoned black]

no you didn't, but can you solve this one xD

I GUESS ITS EASY
first increase is 20% therefore multiplier is 1.2
second increase is 17% of 120% =0.204
therefore final multiplier is 1.404
therefore % increase is 40.4%

although i know that u guyz have already answered ur maths b paper 1 exam ,
would u mind answering this??

A solid heavy sphere of radius 5 cm is completely covered by water and rests on the bottom of a cylindrical tank of radius 6 cm. Calculate the distance in cm, to 3 sig.fig by which the depth of the water in the tank falls when the sphere is removed.

volume of sphere=4/3pie(5)^3=523.5987
523.5987=pie(6)^2h
h=4.63
thanks for the practise!!

 

[poizoned black]

i need more questions where are they????

 

[poizoned black]

dont tell me u guyz solved all of them!!!

The objective of this forum is to help Edexcel mathematics student in any areas of difficulty encountered in their Edexcel mathematics IGCSE exams.

do u thk it will be as difficult as the 3H?

 

[mahmoud631]

problem in mathematics in paper 3H jan 2012 number 4:

The lengths of the sides of a rhombus are 6 cm.
The length of the longer diagonal of the rhombus is 10 cm.
AB is a side of the rhombus.
Construct an accurate, full-size drawing of the rhombus.
You must show all construction lines.

and then drew a line of 6cm please tell me how can i solve it

probably simpler or harder . it is unpredictable
