Answer:
u=(1,1,2), v=(-3,1,2), w=(1,-2,1/2)
Step-by-step explanation:
Since the vectors must be orthogonal, then they must satisfy that the dot product between them is 0.
Then
and .
Solving for y, y=-2z-1 and substituting in the first equation, -3+2z+1+2z=0, then
z=1/2, and y=-2(1/2)-1=-2
Answer:
8
Step-by-step explanation:
Use substitution: substitute each number from the set in for x, and see if the result from dividing is 45.
4
360/x=45
360/4=90
90 ≠ 45
Therefore, 4 does not make the equation true
8
360/x=45
360/8=45
45=45
Therefore, 8 does make the equation true.
16
360/x=45
360/16=22.5
22.5 ≠ 45
Therefore, 16 does not make the equation true.
So, 8 is the value that makes the equation true
