Bas_tet [7]

Answer:

see explanation

Step-by-step explanation:

c = a - 2b

  = < 4, 5, 6 > - 2 < 1, 2, 3 > ← multiply each component by 2

  = < 4, 5, 6 > - < 2, 4, 6 >  ← subtract corresponding components

  = < 4 - 2, 5 - 4, 6 - 6 > = < 2, 1, 0 >

| c | = \sqrt{2^2+1^2+0^2} = \sqrt{4+1+0} = \sqrt{5}

-------------------------------------------------------------------------------------------------

sum the product of corresponding components

u.v = (3 × 2) + (- 2 × - 1) + (4 × - 6) = 6 + 2 - 24 = - 16
