Step-by-step explanation:
2x and 7x is the answer of the questions
Answer: 9/7 or 1.3 (rounded)
reasoning: -2 + 7x/9 = -1
7x/9 = 1
7x = 9
x = 9/7, or 1.3 (assuming they allow you to round to the nearest tenth)
Answer:
Consider the given vectors.
a=3i+2j−6k
b=4i−3j+k
Now,
a⋅b=(3i+2j−6k)(4i−3j+k)
a⋅b=12−6−6=0
Therefore,
Two vectors a and b are perpendicular.
Thus, the angle between the vectors a and b =90
∘
Hence, this is the answer.
