Mathematics: Post your doubts here!

[always-smile :)]

Find the gradients using the points A and B only. That is what it means actually.

sorry i mean in Q7

4.5 cm isn't 0.045 km...
first convert it to metres and then kilometres..
i.e 4.5/100=0.045 m
0.045/1000=0.000045 km
now divide it by 90..you will get the answer

THANKS AGAIN

 

[ahmedali1]

guys from the pastpapers which one do u think was the hardest paper 4 ?

 

[Lost_Life]

Ok Um...., another one
I don't know what to do in bearings, when they say find the side thats EAST of this side

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

THANKS AGAIN

its okie "again"

number 5 c

i didn't really get your question?
izzit from the passpapers or something?

yeah, it is ... MJ 2010 number 5 c

paper? 41? 42? 43?

i have a request..please if possible post the link of the paper with the question

ci) (this method is very long bt not sure of any other ones)
1) put any value of n...say 4
2) equate it to the number of diagonals for that shape i.e in this case 2
3) repeat one and 2 with any other value of n
4) turn it into simultaneous eqn.
5) solve it
6) p should be 2 and q should be 3

cii) its straightforward then
1) take 100 as n
2) put p as 2 and q as 3
3) solve it
4) answer should be 4850

ciii) (again...ive done it with a complicated method which is nt the best way probably)
1) make an eqn. from the formula
2) i.e. n^2 - 3n - 340 = 0 ( i forgot how i got it )
3) solve it
4) answer should be 20

d) no method....LOL just trial and error bt the answer is 31

hope it helps!!!
good luck!!

Terrible question: -.-

B = 3k

Express 9^(2k+2) in terms of B

aoa wr wb..
tell the answer..i will try

I dunno the answer I have been challenged... and i will not fail!

lolz...its cheating then
and well the answer i am getting is 2.08^(2B+6)
(though i need to recheck it..to make sure if i made a mistake somewhere, which i prolly did )

[sma786]

pi x 1.5^2 = 7.1
141.3-15.7 =125.6
12 x pi x 9 =339.3
pi x 4.5 = 63.617
7.1 + 125.6 + 339.3 + 63.617 = 535.617
if you need more details just tell me .. hope u got it

What are these formulae for .?? plz elaborate .. like cylinder circle or wat ?
