©g= -4.5,f=-2.5,c=24.The second point is
(6,2). Just reflect (3,3) in the centre of the circle. (20)

Question 4:
(i) The Angle is 2.5
Radians (ii) The angle is 143 degrees. (10)
(b)
(10,10)
(c) Standard Proof The
Vectors version is probably the easiest
(ii) Just add the cosine
rule for a and b and Simplify. Marks (10,10)

(b)(iii) first red then) green
(b)(iv) One green and one blue
Marks (5,5,5,5,)
©(i) the mean is 2k+4
:(ii) The easiest way to do this part is to use the definition that the
Standard deviation squared is equal to the mean of the squares minus the square
of the mean k=-1. (10,10 marks)

This paper was more
difficult than the first paper. The line question was the most testing, but the
Trigonometry and probability more than made up for this!
