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] )

the determinate of the matrix: <1,-(1),-1>

Which of the following is a proportion? <br><br> A. 4/6 = 6/9<br><br> B. 5/6 = 10/18
worty [1.4K]
Hey there mate!

Your correct answer would be \left[\begin{array}{ccc}\boxed{\boxed{ 4/6 = 6/9}}\end{array}\right] This would be because 4/6 is almost 1 as a whole, and also, 6/9 is almost 1, as a whole, so this would totally make sense for this to be a proportional.

Hope this helps you budd!
