Find a unit vector that is orthogonal to both i + j and i + k.

kenny6666 [7]

Answer: i - j - k

Step-by-step explanation:

Taking the cross product between two vectors will give you a third vector that is orthogonal(perpendicular) to both vectors.

<1,1,0> x <1,0,1>

$det(\left[\begin{array}{ccc}i&j&k\\1&1&0\\1&0&1\end{array}\right] )$

Use unit rate to find the unknown value 16/32 equals blank over 14

grigory [225]

Answer:

x = 7

Step-by-step explanation:

simplify 16/32

16/32 divided by 8/8=2/4

2/4 divided by 2=1/2

1/2 = x/14

1/2 times 2/2 = 7/14

so x = 7
