Given the vector OP = -4i + 3j, |OP| is:
25.
1.
5.
7.
The figure is a vector diagram where OA = a, OB = b and BE = 2OA, then AE is:
a + b.
3a + b.
-a + b.
a - b.
Given that a = 5i + 7j and b = 4i − 5j, then a − 2b is:
3i + 3j.
-3i - 3j.
3i - 17j.
-3i + 17j.
Given the vectors a and b, a + b is:
A.
D.
C.
B.
The direction of the vector -3i -3j is:
45°.
225°.
135°.
315°.
