Saad Mughal u said u made a mistake in P2..what was it?....i think i could ans all correctly.

Well, It was a dead dumb mistake. You know the parallelogram question? The transformation one? Well, I read the vertices ABCD and PQRS instead of ABCD and PBQR (just a dumb mistake) and described the CENTER incorrectly. The center was B. I didn't have enough time to check my paper again, else I would've surely corrected it. 1 mark lost because of this.

 

[Saad Mughal]

What I did was,first calculated for 8 hours.
Then for 15 minutes.
Although I didn't add both as the question clearly highlighted that she was paid for every hour.

Look. CIE is a real messed up board. For all we know, the answer could be anything. So, let's just forget it.
P.S. 1 mark was for correct time calculation and 1 mark for the correct answer so I'm sure everyone calculated the time correctly AT LEAST.

ahah, yeh, i am very weak at remembering answers

 

[Saad Mughal]

Er.. Guys. I have a question. How light and thin was your graph?
And what was the gradient?

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

Yeah

gradient was 5

is this the second question from section B...i didnt answer that one...

well, i dont remember even bit of the gradient. maybe zero piont something or 1. something... sorry i dnt remember

 

[Saad Mughal]

Yes, the second one.

 

[sourov97]

maybe 5

 

[Saad Mughal]

I'm talking about YOUR graph's gradient, not the other one. It was -0.8.

Yes,everyone did
Hoping for the best.
I guess,they are lenient enough to credit us because the question didn't clearly mention.

 

[Saad Mughal]

gradient was 5

maybe 5

I got 6. I got 5 at first, then I further stretched the tangent and got 6 from it's equation.
The correct exact gradient was 4.5 and I'm hoping that my answer is in range.

 

[sourov97]

one more: ...what was the solution...the last question from the graph..maybe the equation was sht like 2x^3 - 3x^2 + 4 = 0

 

[Ammarfasih]

Yes.

Yr saad i showed the whole working of simon credit N all ..! Wrote even lydia but unfortunately i misread N thought that we have to state the price so i wrote the whole price of her ... !

one more: ...what was the solution...the last question from the graph..maybe the equation was sht like 2x^3 - 3x^2 + 4 = 0

you had to draw the line y = 1 and ans was like -0.91

 

[Saad Mughal]

one more: ...what was the solution...the last question from the graph..maybe the equation was sht like 2x^3 - 3x^2 + 4 = 0

-0.9, error of 0.1 which is always in range.

If you showed all the working and everything then made the correct conclusion, you might get the mark(s).

What was the difference between Lydia and Simone?
