a) 4/(4+5)explain it plz???View attachment 43534
b) There are a total of 7 'units' (3+4). The unit of girls is 1 more than boys. That means 1 unit represents 120.
1 : 120
7 : x
cross multiply and solve.

Nearest tenth of a degree? Isn't it supposed to be 10? :/Angle B is 53.4 correct to the nearest tenth of a degree (0.1)
0.1/2 = 0.05
53.4 + 0.05 = 53.45 --> UB
53.4 - 0.05 = 53.35 --> LB
Upper Bound of Angle C so Angles A and B must be smallest (LB) to get highest C.
Upper bound of C = 180 - LB of A - LB of B
UBC = 180 - 53.35 - 61.5 => 65.15
D = 0.5 * 20 * u
Nearest ten degrees = 10Nearest tenth of a degree? Isn't it supposed to be 10? :/

Question 11 b part.
Question 24, can anyone construct the locus please?
Yeah.Pattern/nth term formula?
Thanks a lot.0 = x^2 + x -12
solve to get 2 values for x. Negative one will be l and positive one will be m.
For 24, draw a circle of radius 5 cm, center C then the angle bisector of B. P will be the point where the angle bisector cuts the circle inside the triangle.
part a is solved above.

Question 11 b part.
Question 24, can anyone construct the locus please?
Can someone post all the matrix of transformations; how to sketch matrices etc etc. Not the Matrices chapter - just the matrix part of transformations
"g (0)" means the value of x = 0
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
