it is given that a=7 as x coordinate and 14 as y coordinate and IBI=50.if a =hb where h is a negative constant, find the valure of h. hence find b... this is from vectors chapter in d4 q10 ex3c

Q12 of this paper: http://www.xtremepapers.com/CIE/Cambrid ... 6_qp_1.pdf
(a) BA = BC + CO + OA
= -a - 2c + 4a
= 3a - 2c

(b) 2/3 (3a - 2c) = 2a - 4/3 c
=> 2/3 BA = OP
Hence, OP is parallel to BA.

(c) Triangles OBA and OPA share the same base. Therefore, the ratio of their areas = ratio of any two consecutive lengths = BA/OP = 3/2

Re: O'level Maths, Addmaths and Statistics help available he

As Salman is uploading the solution ill just tell u that u use ratios to find the length and then divide the lengths to find k and then as it already tells abt the lines being parallel u state that the points are collinear and tell the ratio which connects the three points.!
