Please explain how to do this question of vectors: In the diagram, OP=p, OQ=q and PX= XQ.
Express in terms of p and q
(i) PX
(ii) OX
(b) Given that OR= 3/4p+3/4 q, write down the numerical value of ratio RX/XO.

Answer 1

Mid point formula
\[OX=\frac{OQ+OP}{2}=\frac{p+q}{2}\]
PX=OX-OP

Answer 2

What about part (b)?

Answer 3

is it 1:2

Answer 4

It is.
