use unitary method

for 5 it costs 330p

so for 1 choc it will cost 330/5

to get 9,

 (330/5) =66

66 multiplied by 9 =594

therefore 9 will cost 594p

Determine whether the vectors u and v are parallel, orthogonal, or neither.
kicyunya [14]

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
