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.

A rectangular prism has a volume of 572 cubic inches. The prism is 4 inches long and 13 inches wide. What is the height of the p
Leya [2.2K]

Answer:

Height of rectangular prism = 11 inches

Step-by-step explanation:

Given that:

Volume of rectangular prism = 572 cubic inches

Length of prism = 4 inches

Width of prism = 13 inches

Volume of prism = Length * Width * Height

572 = 4 * 13 * h

572 = 52h

52h = 572

Dividing both sides by 52

\frac{52h}{52}=\frac{572}{52}\\h=11

Hence,

Height of rectangular prism = 11 inches

For the following inequality, indicate whether the boundary line should be dashed or solid. x ≤ 5
lukranit [14]
Answer: The boundary lien should be solid because the inequality indicates that the value “5” is included. Remember: “greater than or equal to; less than or equal to,” as solid lines. While “<;>” are dashed lines.
