in 2012 o/n v41 question (6a2) plzz answer

|b| means the maginitude (length) of the vector b.

If you draw the vector b, you can make a right-angle triangle with perpendicular lengths 2 and 7. You can use Pythagoras to find the magnitude which is the hypotenuse.

There should be 2 intersection points. I would need to see your graph to find your mistake.

the picture is not uploading anyways leave it n plz ans this 1

but sir this is matrices so why is this not the derterminant......

You can only find the determinant of a square matrix e.g. of order 2x2 or 3x3.

This is a column vector so |b| means the magnitude of b, and not the determinant.

I'm not going to answer the whole question. Please show me all the working/ideas that you have. And then tell me the specific parts that you can't do.

okay sir could u explain this question shortly then i will try to solve this question

Which part? I can't explain the whole question - it's too long.

can anyone provide me with pure mathematics mark scheme held on 7th may (paper 12)

can anyone provide me with pure mathematics mark scheme held on 7th may (paper 12)

Please can you not post this here. This thread is designed for past IGCSE questions.

I doubt anyone on here has that mark scheme so I'd stop trying if I were you.

10 a 1 and 2

To be honest, 10ai is a pretty easy question:

a=7, b=9, c=17, d=19

So bc-ad = 9*17-7*19 = 20


ii. Have a look at the grid and you'll see that a (7) is 6 less than n (13) so a=n-6. Can you do the same thing for b, c and d?

O/N/01 Question 3)a)

Paper 4 or Paper 2?

 

[Ijlal Amir]

Paper 4 or Paper 2?

Paper 4 Obviously we have finished paper 2 lolz xD

O/N/01 Question 3)a)

Two triangles are similar if all of their angles are equal.

<MNO = <OPQ (alternate)
<NMO = <OQP (alternate)
<MON = <POQ (opposite)

Therefore, triangle MNO is similar to triangle QPO.

could you answer the rest of the question pleaseeeeee Thank you

also ive noticed theyre repeating the old past papers !! So id advice you to do them guys
