Yes.

Posting in capitals won't make me answer faster - I will answer every question when I decide to.

This is just a rotation like any other but here you have a line instead of a shape that you are used to. You can use tracing paper to rotate the vector.

Heheh, Anyways Thanx Alot! Anything except tracing paper?

There are 10+5=15 students who attend both drama and music and there are 90 students in total. So the probability is 15/90.

How do you normally rotate a shape? I recommend tracing paper but you could do it just by looking if you want.

A matrix method should not be used here since the IGCSE transformation matrices are designed for transformations about the origin (0,0). Plus it would be a complete waste of time

 

[notnek01]

so the last number in this sequence indicates the term

Yes.

I answered this question above.

Are you alamgir?

 

[Rania1]

I answered this question above.

Are you alamgir?

Nope, i will go see it thanks alott

 

[notnek01]

Nope, i will go see it thanks alott

It's quite a coincidence that both you and alamgir asked for help with the same question (dii) on the same day but made a mistake and actually wanted help with (eii).

If you're not the same person, then you should meet - I'm sure you'll have a lot in common

[Rania1]

Q

october november 2012 43
question 4 part (d)

question four has no part D

 

[notnek01]

question 4 part (d)

f(x)=3x --> (2/x^2) - 3x = 3x

--> 2/x^2 = 6x

--> 2 = 6x^3 --> x^3 = 2/6 = 1/3

So k = 1/3.

 

[notnek01]

Q
question four has no part D

Yes it does?

 

[inquisitiveness]

in gradient using tangent method,how many decimal places/significant figures should the answer be?
