Let u = PQ be the directed line segment from P(0,0) to Q(9,12) and let c be a scalar such that c < 0. which statement best de
scribes c u?
2 answers:
Answer with explanation:
⇒u= P Q
Coordinates of P = (0,0)
Coordinates of Q= (9,12)
There is also a scalar,c such that, c<0.
Now, we will first find ,→ c P=(0,0)
→c Q= (9 c , 12 c), where c, is less than 0.
→c u=c × P Q
Both , 9 c, and 12 c, will be negative, So, this point will lie in third Quadrant.
Option A: The terminal point of vector cu lies in Quadrant III.

For this case we have the following expression:
By definition, a coefficient is the term that accompanies one or more variables.
For example:
The coefficient of the linear term is 3.
So, in the given expression we have to:
-4 is the term that accompanies the variables xy.
Answer:
-4
