C1 amazing exam!!

[Hailstorm94]

length of line was root 160

idk if u get marks for it i simplified it to 4 square root of 10

 

[ahmed soliman]

l1 and l2 intersect at (3,6)
k=1/16
in same question x=-1/4 and y = 3/2
sum of sequence = 27000

i simplified it to 4 root 10

 

[ahmed soliman]

did anyone get inequality x>-1

 

[ahmed soliman]

for sequences i got 324k.. since i took that after 21 d was 600... u guys sure there was no difference after that?

yes

 

[Hailstorm94]

how many marks was that part? 3marks?

 

[MerdeonaStick]

can anyone post the full answers please?

 

[ahmed soliman]

how many marks was that part? 3marks?

5 marks but u will get some marks for finding sum of 21 terms
tell me about inequality is it x>-1

 

[akhmed]

wasn't the inequality in the form ax^+bx+c<0? I thing I got answer in the form ,for example ( -3/4 <x<1 )

i mean part a)

 

[ahmed soliman]

part b was in the form u said

 

[ahmed soliman]

part a ) was a normal inequality plz tell me was it x>-1???????

what was the equation of line L1 ?

 

[Herald Grove]

Here is what I remember:
C=-2
Length=4*10^-2 (just the root of 160)
m= -1/3 so m of normal 3
Sn=270000 (OR maybe 27000)
K X Y don't remember but there was only one value for X and for Y.

The C1 was a perfect paper; very easy, unlike the 'D' Mechanics!

 

[ahmed soliman]

what was the equation of line L1 ?

i dont remember but do u remember x>-1

 

[Madness]

i dont remember but do u remember x>-1

nop :'(, what was the equation of the line L1 ? wasn't it somethingx 2y+45 ?

 

[Herald Grove]

i dont remember but do u remember x>-1

You seem so fixated over that question. I think it was 2 marks and the answer was x>-1. What did you get for part b of the same question?
I got -3<x<1/3!

 

[Herald Grove]

nop :'(, what was the equation of the line L1 ? wasn't it somethingx 2y+45 ?

Another simple part a question...no it wasn't! Don't remember exactly but I know there was no 45!

 

[DC1313]

yeah i dont remember a 45 too. but i dont remember my answer either. and yes i also got x>-1 to those who are asking.

 

[ahmed soliman]

nop :'(, what was the equation of the line L1 ? wasn't it somethingx 2y+45 ?

i think that equation had 15 or -15 dont remember
