This is one of the hardest paper i solved , and i have a lot of Q ,, please help me ..

Q 2 a iv , why the factor is -1 but not 1 ?

Q3 C

Q6 D

Q7 C ii

Q8 C iii

Q10 C , f , g

Solve the one you know , plz help

for 8c use yo scale to know how many squares are one centimeter horizontal and vertical
so you will know 5 boxes vertical and horizontal are 1 cm
and vertical is X axsis so now you know for i cm^2 you will have 5 frequency density
and horizontal is Yaxisis so no you will have 0.5 minutes on the y axsis as the time
The formula is Frequncy Density= Frequency/Class with
5=x/0.5
5*0.5=2.5 i hope yo understood i will work on your other questions too

I know almost NOTHING about maths except for algebra and trigonometry and graphs and geometry which I learned since the exams started :|..(our maths teacher got replaced 3 times >.>")...
what are my chances of passing this exam?
I solved pretty well in paper 12or at least that's how I feel.. I need huge help in metrics and transformations and predictions and estimations (idk name sry). any help is appriciated thanks..

di) is 4 because as we mentioned in bi) that it is constant

ii)g=x+2n and i=g=2 which is x+2n+2

iii)c=x+2
therefore: (x+2)(x+2n)-(x)(x+2n+2)
=x²+2nx+2x+4n-x²-2nx-2x
=4n

hope this was helpful

SEQUENCES-Points to remember:
Many people find it hard, but to be honest it's just more of logic..that's all!

Sequences!

Using log for indices.

Can someone please write down all the formulas needed for mensuration in maths p4..

 

[notnek01]

I'll post my formula list for a last minute checklist before the exam:

=4n

Tnx a billion...it was rele vry helpful...

 

[shazmina]

its G= X+2n and I=x+2n+2 .... as they said the box is n x n sooo when u go down from the top to the bottom thats 2x and yeah but for I there are 2 more boxes to go to.... so those are calculated as numbers... as u know it adds up by one each time it moves to the left so +2... i hope u get it.... because this is very easy!

Tnx a billion...it was rele vry helpful...
