Do you mean 4ai and 4aii ?
4ci:no 4c i nd ii nd 7 b iv pls help
You only need to know the method for arithmetic sequences where the nth term is of the form: an + b. (Can you do these?)Guys,
I don't understand how to make the equation for the nth term?
Especially the hard ones, where you have to use square and cube..
Do you mean Paper 4, Question biii? In future, please say exactly which paper and which question part you need help with.How to solve the inequalities using the graph?? Any Help?? the question about it is on Oct/Nov 2009 Question 6
10) 'The glass can be filled with water from the jar exactly 216 times.' This means that the volume of the jar is 216 times the volume of the glass i.e. the volume scale factor = 216.can someone help me on question no 10 and 11

10) 'The glass can be filled with water from the jar exactly 216 times.' This means that the volume of the jar is 216 times the volume of the glass i.e. the volume scale factor = 216.
Length scale factor = cube root ( Volume scale factor) = cube root ( 216 ) = 6.
Can you finish it from here?
11) You need to use the cosine rule:
21^2 = x^2 + (2x)^2 - 2(x)(2x) cos(120)
--> 21^2 = 5x^2 - 4x^2 (-0.5)
Can you solve the equation from here?
I don't think they were every released, sorry.Does anybody have an idea of where I can find the overall threshold for mathematics before June 2011? And do I always have to score above 175 to guarantee achieving an A* ?
AsSalamoAlaikum Wr Wb...
Stuck somewhere in Maths?? Post your queries here! Members around will help you InshaAllah.
NOTE: If you have any doubt in the pastpper questions, then kindly post the link to the paper!
May Allah give us all success in this world as well as the HereAfter...Aameen!!
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.
This is a very standard (inverse) proportion question - they're always very similar so you need to get used to the method:y ıs ınversly proportıonal to x^2
when X=4 Y=3
find y when x =5
by / did u mean division?This is a very standard (inverse) proportion question - they're always very similar so you need to get used to the method:
y is inversely proportional to x^2 --> y ∝ 1/x^2 --> y = k/x^2
When x=4, y=4 so substitute this into the above equation to find k:
3 = k/4^2 --> k = 16 x 3 = 48.
Now putting this value for k into the equation:
y = 48/x^2
Find y when x=5. Can you do this now?
Yes. 1/x^2 means a fraction with numerator 1 and denominator x squared.by / did u mean division?
thnx i solved it ans is 1.92 )Yes. 1/x^2 means a fraction with numerator 1 and denominator x squared.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
