[Saifyyy]

I

Yeah

If we didn't write center of enlargement as B and just write Origin (0.0).. it is the same right ?

 

[Saad Mughal]

I

If we didn't write center of enlargement as B and just write Origin (0.0).. it is the same right ?

No. The origin means that a point O (from which position vectors lead). Center of enlargement was B. I wrote origin. It's INCORRECT.

 

[Saifyyy]

Man B itself was origin..
I can prove that..

 

[Saad Mughal]

Man B itself was origin..
I can prove that..

No, you can't. In vectors, the origin is O (0,0). Not B. If B was the origin it would have coordinates (0,0). The fact is, they WANTED us to derive this from ABCD and PBQR, which many of us didn't which means we'll lose the one mark.

 

[Mahnoor Ahmad]

It was enlargement about B with a scale factor of 3,right?

I didn't write center at all. In any case from the alphabets it could easily be guessed what we really had to deduce was the enlargement and scale factor center was obvious.

 

[Mahnoor Ahmad]

What happens if i wrote 2? is it wrong? because i rounded off lydia's amount to 8562 so i couldn't give the answer exact because they tell us to round it off.

$1.52

 

[Mahnoor Ahmad]

No half marks awarded you get either 1 or 0

You'll get at least 1/2.
