pls solve it fo me

no i dun hv

There are three rules on determining how many significant figures are in a number:
1. Non-zero digits are always significant.
2. Any zeros between two significant digits are significant.
3. A final zero or trailing zeros in the decimal portion ONLY are significant.

i.e.
0.0004
It has one significant number, 'cause we don't count zeros before the number.

900.06
It has five signifcant numbers.

10.0
This one has 3 significant numbers,

no,there are 2 values of x, we have to solve it further

I think so you can do it yourself now
Just solve the above equation n you'll get two values of x.

 

[***amd***]

what is a proper set?
8 is a cube number ?

whose all elements are a part of the other set.
yes, 2 ka cube is 8

faizan Muhammad, ^ according to this def. {} is improper, and (1, 2, 3) is a proper subset of the set {1, 2, 3). no?

 

[Maganius]

pls solve it fo me

Is 2 the answer of first part?

show me the solution till the equation?

isn't it a subset then

 

[exploded diper]

No we have to take 10,i saw it in the classified and also the ER.

r u sure......
do u mean for <50 etc...
or for a range 10<x<20...

 

[exploded diper]

Faizan Muhammmad
give him the link.

link de kay kuch samaj nahi ayi gi..tum samjhado..
waisay yeh kis tarhan ke question me aata hai.....

 

[Maganius]

show me the solution till the equation?

As the equation of the line is ( y=mx+c)

Q: 3y=2-x
As 2 is in the place of *m* therefore the answer is two.

I'm not sure about that second part though

Draw a line with the points P Q and M and R on a piece of paper. M is midpoint of PQ while PR is thrice PQ so when PM is 1/2 PR is 3 so when PM is 1 PR should be 6.

how is PM 1??

this is wrong :s i was referring to that 5y+.. question

Q18 c

 

[asadalam]

A useful way to form matrices in case you forget :

 

[FLRNAB]

i know, but they cant give Q for which students are all helpless to find any method. They always give whose Qs from out of syllabus for which candidates can at least make a wild guess.

Candidates make guesses when they are helpless. -_-

Once upon a time there were was a great curse on the poor inhabitants of the hall of CIE. The witch named "Rxaminer" roamed without being seen and in the month of july papers would fall out of the sky. They contained the words "Only the strongest candidates could answer this question"

Q18 c

Equation in b: n x (n+1) + (n+2)^2

Expand and simplify this to get 2n^2 + 5n + 4

Compare coefficients to obtain 2,5,4.

why in part (c) is the matrix showing the shear factor as -2???
and can someone solve the shear part for me plsss thnx....
