Find the horizontal component, a, of vector u. y 3 45° a The horizontal component of u is (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)

Use the dot product properties to evaluate each expression in the left column and match its corresponding answer in the right column. Let u = (4,5), v = (1,-6) and w = (-7,-3). :: -14 V. W u. (5v) VW- u. W (2w) • u + v v. (u - w) :: -64 :: 159 :: 54 :: 59 :: 11 #130 :: -37 :: -130 I :: -25
