Answer: B

Step-by-step explanation:

To find the inner product of two vectors (a,b,c) and (d,e,f) you would use the equation (a * d) + (b * e) + (c*f)

So for (-2, 4, 8) and (16, 4, 2) the inner product would be

(-2 * 16) + (4 * 4) + (8 * 2)

= 0

The vectors are only perpendicular when the inner product is equal to 0. Since it is equal to 0 in this case, the vectors are perpendicular.

B - 0; yes

Answer:

b) 0; yes

Step-by-step explanation:

a•b = (x1 × x2) + (y1 × y2) + (z1 × z2)

= (-2 × 16) + (4 × 4) + (8 × 2)

= -32 + 16 + 16

= 0

Hence they are Perpendicular
