Maths Paper Discussion 12 and 22

[Farhan Saeed]

What was the answer to that vector question in Section B, about transformation. My friends wrote the parallelogram would be enlarged by 3 factor. I wrote the two way stretch of factor 3. Is it correct.

 

[Blackcat17]

If you say a two way stretch, then have you mentioned the invariant line?

We're not allowed to discuss yet. Please wait till tomorrow.

[Mahnoor Ahmad]

I didn't write center B.

It was Enlargement with centreat B, and Scale factor 3...........................Two way stretch with the same stretch factors on both sides is the same thing.............

 

[Saad Rasool]

I didn't write center B.

But the Centre of Enlargement has to be given incase of enlargement................

 

[Mahnoor Ahmad]

how much will I lose for writing enlargement with scale factor 3?

i wrote two way stretch too with the stretch factor of both y and x =3. its correct. dont worry.

can somebody provide me with a very resourceful addmaths online website. i heard of a teachers website thing. i forgot. help asap

there is no as such invariant line in a two way stretch hahahahaha. its only when parallel to x or y.

i cant access the teacher's website but the student's website had a learner guide you can find it here http://www.cambridgestudents.org.uk/subjectpages/maths/oladmaths/

yes, it was enlargement, with b as centre of enlargement and with factor 3.

 

[Mohammad Farzanullah]

yes! it was enlargement of scale factor 3 and centre at B!

 

[Danish Alvi]

If I write that the centre of enlargment as the origin (0,0), which I am quite sure was (I multplied the vectors of parallelogram ABCD with enlargment matrix with centre as (0,0) ) what is wrong I believe it is correct....please discuss more questions as 24 hours is over and there is no problem now

May be a single mark b/c complete question was worth 2 marks.............

 

[Mahnoor Ahmad]

ok . what was SR? mine was (9,9)

it was an enlargement with the scale factor on 3 and the center of enlargement point 'B'

 

[Mohammad Farzanullah]

ok . what was SR? mine was (9,9)

(7.5)
(3)

Hey that total of fence I calculated came to be 832 and further upin decimal to two places but I guess answer was more than 1000 as we had to find 220 percent while I guess I found 120 percent using ratio method as I wrote 100 percent in 378 so how much will be in 220 but will my all marks be gone,I am worried and that was in locus question we had to use Pythagoras theorem,I used it,some measured it,and I forgot to write answer to AF but wrote 7 cm in working I guess
