Answer: A
Step-by-step explanation:
To find the inner product of two vectors (a,b) and (c,d) you would use the equation (a * c) + (b * d)
So for (7,2) and (0,-2) the inner product would be
(7 * 0) + (2 * -2)
= 4
The vectors are only perpendicular when the inner product is equal to 0. Since it is equal to -4 in this case, the vectors are not perpendicular.
A -4; no
Answer: 3+3=9
⇔
Step-by-step explanation: three fingers to start add three fingers total of nine
I think it's 3
It should be 3 because if you have a base of 6 then your height must be 3 to get 18.
