wht was the answer for question 7 ??
and what was K in the sequence question ??
oh and about the cuve question was the function "increasing , decreasing or neither ? "

i cannot remember k however the function was increasing as it was (x)^2

R was (7, 15)
K came out to be something like a 63 and 21, i forgot which one had the negative sign./////
dont know abt the function but i wrote decreasing because the gradient decreased as u increased x

 

[SB29597]

i think i got something like 7 and 15 i found y then then the inverse of y substituting the points to find the reflection

I thought about doing the inverse thing, but then the perpendicular line idea made more sense. We have the same x- coordinate though :/
So whats correct? :O

For question 7 i got (7,15) for R. Please tell me someone got the same answer :/

For question 7 i got (7,15) for R. Please tell me someone got the same answer :/

yes the ans was (7,15) but by mistake i wrote 7,16

function was increasing bcz when u put the vaule of x in (dy/dx) ,its value starts to increase which means that it was increasing

 

[Hassan Ali Abid]

How did you solve the parallel vector one? I'm not sure if I got that one right :/

by multiplying that vector with 3 .......the ans comes and i think the value of p and q were 6 and -6 ..

 

[rjcooo1]

I got that one wrong then

K = 63 and -21
Question 7 answer R(7,15)
Curve was increasing

 

[FRENZYAMU]

function was increasing bcz when u put the vaule of x in (dy/dx) ,its value starts to increase which means that it was increasing

but the denominator had a square and the denominator increased when u increased x therefore the overall gradient decreased....nyways whats done is done

 

[Hassan Ali Abid]

but the denominator had a square and the denominator increased when u increased x therefore the overall gradient decreased....nyways whats done is done

i dont remember but the fuction was increasing and im 100% sure

 

[FRENZYAMU]

i dont remember but the fuction was increasing and im 100% sure

first part ws to calculate derivative of function which is offcourse gradient nd im 100% sure it had a square in denominator which decreased its value, the derivative's......

i know there was square and i did that part with great care and the function was increasing

 

[FRENZYAMU]

i know there was square and i did that part with great care and the function was increasing

oh no plz it was decreasing,,,,it was something similar to this in the denominator (3-x)^2

 

[Hassan Ali Abid]

idk ....but im telling u im 1000 % sure that it was increasing .......... u are talking about that part b of functions ????? rite ?????

 

[SI UNIT]

Can anyone tell me how much we have to get in P12 to get an A* !? Thanks!

gt of getting A is about 60 marks in p1 so i think 70 and above ...

oh okay, thank-you. =)

 

[Hassan Ali Abid]

oh okay, thank-you. =)

np
but im telling u to score this much if u are weak in stats and m1 .......getting B in those components and scoring high A gardes or full marks in p1 and p3 can easily make A* .

My math paper 1 exam was the worst math exam I ever wrote!! :'( I think I lost 10 marks!! =( Usually I always get 72-75. This has just been horrible for me!! It's not like the paper was hard, my luck was just pure plan bad! =/ =(

But thanks for ur advice, =) now my only hope is to get close to full marks in M1.
