### Educational Exercise: Working with Vectors
**Problem 20:**
Consider the following vectors in \(\mathbb{R}^3\):
\[ \mathbf{u} = \begin{bmatrix} 1 \\ -6 \\ -7 \end{bmatrix}, \quad \mathbf{v} = \begin{bmatrix} 3 \\ -4 \\ 7 \end{bmatrix}, \quad \mathbf{w} = \begin{bmatrix} -2 \\ 7 \\ 5 \end{bmatrix}, \quad \mathbf{x} = \begin{bmatrix} 0 \\ 8 \\ 9 \end{bmatrix} \]
#### Instructions:
1. *Identify and describe* the vectors given above.
2. *Perform operations* (such as addition, scalar multiplication, etc.) as required by the specific question context (which is assumed to be provided in the original exercise set).
#### Explanation and Application:
- **Vectors are fundamental in understanding and representing physical quantities** in multiple dimensions. Each vector listed is a column vector in \(\mathbb{R}^3\), meaning it has three components.
- **Applications of these vectors** can range from physics (e.g., force representation) to computer graphics and machine learning. The operations performed on these vectors (like addition and scalar multiplication) help in transforming and analyzing data in numerous scientific and engineering fields.
#### Example Questions (based on given vectors):
1. Calculate \(\mathbf{u} + \mathbf{v}\).
2. Find \(3\mathbf{w} - 2\mathbf{x}\).
3. Determine the dot product \(\mathbf{w} \cdot \mathbf{u}\).
4. Check if \(\mathbf{v}\) and \(\mathbf{x}\) are orthogonal.

Ensure that the learners understand **the format and representation of vectors** in linear algebra. The exercises derived from such problems provide a strong foundation for more complex vector operations and their applications in various domains.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F12a9a3e9-d100-4e80-b765-c2c582e29977%2F0a74c78d-d48f-4a23-892a-8fd598dd3c6f%2F6mjbcqh_processed.png&w=3840&q=75)
