Answer with explanation:
Initial Point of vector , u= (-7,2)= -7 i + 2 j
Terminal point of Vector , u= (11, -5)= 11 i -5 j
Vector , u= Terminal point - Initial Point
= 11 i - 5 j - (-7 i+ 2 j)
= 11 i - 5 j + 7 i - 2 j
= 18 i - 7 j
⇒Vector, v= 3 ×Direction Opposite to that of vector, u
= -3 u
= -3 × (18 i - 7 j )
= 3× (-18 i + 7 j)
= -54 i + 21 j
Answer:
4w+120.
