![### Linear Algebra: Vector Projection Problem
#### Problem Statement:
Compute
\[ \left( \frac{\mathbf{x} \cdot \mathbf{w}}{\mathbf{x} \cdot \mathbf{x}} \right) \mathbf{x} \]
using the vectors
\[ \mathbf{w} = \begin{bmatrix} 4 \\ -1 \\ -3 \end{bmatrix} \]
and
\[ \mathbf{x} = \begin{bmatrix} 5 \\ -3 \\ 3 \end{bmatrix} \]
#### Solution Steps:
1. **Compute the dot product of** \( \mathbf{x} \cdot \mathbf{w} \).
2. **Compute the dot product of** \( \mathbf{x} \cdot \mathbf{x} \).
3. **Evaluate the expression** \( \left( \frac{\mathbf{x} \cdot \mathbf{w}}{\mathbf{x} \cdot \mathbf{x}} \right) \mathbf{x} \).
#### Inputs:
- \(\mathbf{w} = \begin{bmatrix} 4 \\ -1 \\ -3 \end{bmatrix}\)
- \(\mathbf{x} = \begin{bmatrix} 5 \\ -3 \\ 3 \end{bmatrix}\)
**Note:**
Simplify your answer. Type an integer or simplified fraction for each matrix element.
