Question

Find the inner product for (4,8) (6,-3) and state whether the vectors are perpendicular.

Answer 1

`= \binom{4}{8} . \binom{6}{ - 3} \\ = (4 * 6) + (8 * - 3) \\ 24 + ( - 24) \\ = 0 \\ since \: inner \: product \: is \: zero : \\ the \: vectors \: are \: perpendicular`

Answer 2

0

The vectors are perpendicular

Explanation:

(4,8) (6,-3)

The inner product is also known as the dot product

4*6 + 8*-3 = 24-24 = 0

The vectors are perpendicular since the dot product is zero
