can any one plz help me in this question last part
Relative to an origin O, the position vectors of points A and B are 7
24 and 10, 20 respectively.
Find
(i) the length of OA, [2] ans 25
(ii) the length of AB . [2] ans 5
Given that ABC is a straight line and that the length of AC is equal to the length of OA, find

Ans of q9
you will have to fix pieces and then make possibilities
for e.g. fix one piece of Beethoven then take two of Handel and one of Sibelius, then one of Handel and two of Sibelius. like this you would make possibilities and then add those.

Ans of q4 is in the attachment

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

can any one help me

as you have found the length of OA and AB which is 25 and 5 respectively
OA=AC
we would make ratio
AC:AB
25:5
or AC=5AB
OC - OA = AC
OC = AC + OA
the answer is (22,4)

can u explain y we have taken ratio it was simply OC-OA=OA
