Find two unit vectors orthogonal to both given vectors. i j k, 4i k
Maurinko [17]
The cross product of two vectors gives a third vector \mathbf v that is orthogonal to the first two.

\mathbf v=(\vec i+\vec j+\vec k)\times(4\,\vec i+\vec k)=\begin{vmatrix}\vec i&\vec j&\vec k\\1&1&1\\4&0&1\end{vmatrix}=\vec i+3\,\vec j-4\,\vec k

Normalize this vector by dividing it by its norm:

\dfrac{\mathbf v}{\|\mathbf v\|}=\dfrac{\vec i+3\,\vec j-4\,\vec k}{\sqrt{1^2+3^2+(-4)^2}}=\dfrac1{\sqrt{26}}(\vec i+3\,\vec j-4\vec k)

To get another vector orthogonal to the first two, you can just change the sign and use -\mathbf v.

Find the value of x and y
hram777 [196]

Answer:

  • x = 12
  • y = 20

Step-by-step explanation:

There is nothing in this diagram to suggest any particular values for x and y.

__

If we assume the figure is intended to be a kite, symmetrical about its horizontal diagonal, then each segment is congruent to the one above it.

  x = 12

  y = 20

M<MRT 133. What is m<MRN?
liberstina [14]

Answer:

MRN+NRT=MRT

2g-2+4g-9=133

6g-11=133

6g=133+11

6g=144

g=144/6

g=24

MRN=2g-2

=2(24)-2

=48-2

=46°

Hope it helps:-)
