one zero
hope it helped if i didn't please write back and ill try my best for further explanation
Answer:
B.) Orthogonal
Step-by-step explanation:
Two vectors u and v whose dot product is u·v=0 are said to be orthogonal
u = <6, -2>, v = <2, 6>
u·v = u1*v1 + u2*v2
6*2 + -2 * 6
=12 -12
=0
I think its 210 because there are 7 letters and 3 vowels so the permutation would be 7 P 3.
Counting by 10 is called base 10
