Dovator [93]

Answer:

Maria did her job properly. Both gears are perpendicular.

Step-by-step explanation:

Recall that given vectors a and b, they are perpendicular if and only if $a\cdot b$ =0. If $a=(a_1,a_2),b=(b_1,b_2)$ . Then $a\cdot b = a_1b1_+a_2b_2$ .

IN our case a=(5,-1,2) and b) (1,-3,-4). So,

$a\cdot b = 5\cdot 1 + (-1)\cdot(-3) + 2\cdot(-4) = 5+3-8 =0$

So both gears are perpendicular.
