Some questions here. Would like you guys to help me check my
answers. Thanks.(:
My answer is the 2nd option.(not sure if this's right) But I
chose a point of origin 2 squares below popint C. The
"y-coordinate" moves down by 2 units the the x-axis needs to shift
4 units to point D. That's how I derived my answer. Is this method
valid?
For this I got 10%.
Next comes the most "mind-boggling" question I came across in
this assignment. HAHA. Not tough actually, just that I don't know
how to present my answers though I got the correct choice.
Just need help with presenting the "express vector OC in terms
of h, p and q" part
I got h = 2 and k = 3/2.
No problem finding value of k. But for value of h, I actually
used the A maths method of intercept theorem to confirm my answer.
But I don't really know how to present my answer for the 1st
part.
Once again, thanks
For your 1st question, yes, your method is valid.
For your 2nd question, the answer is correct.
For your 3rd question, the workings are as followed:
OF = 1/2 OE = 1/2q
EA = EO + OA = OA - OE = p - q
ED = 1/2 EA ( Since F is the mid point of OE and FC // OB ) =
1/2 ( p - q )
FD = FE + ED = 1/2 q + 1/2 ( p - q ) = 1/2 p
FC = h FD = 1/2 hp
OC = OF + FC = 1/2 q + 1/2
hp
