Question
**Linear Transformation and the Rank-Nullity Theorem**

Let \( T : U \to V \) be a linear transformation. Use the rank-nullity theorem to complete the information in the table below.

| \( U \)      | \( \mathbb{R}_{1 \times 3} \) | \( \mathbb{R}_{2 \times 2} \) | \( \mathbb{R}_{7 \times 4} \) |
|--------------|----------------|----------------|----------------|
| \(\dim(U)\)   | 3              | Ex: 5          | Ex: 5          |
| \(\text{rank}(T)\) | 2              | Ex: 5          | Ex: 5          |
| \(\text{nullity}(T)\) | Ex: 5          | 3              | 4              |

**Explanation:**

- **\(\dim(U)\)**: Represents the dimension of the vector space \( U \).
- **\(\text{rank}(T)\)**: Represents the rank of the linear transformation \( T \).
- **\(\text{nullity}(T)\)**: Represents the nullity of the linear transformation \( T \).

The Rank-Nullity Theorem states:
\[
\dim(U) = \text{rank}(T) + \text{nullity}(T)
\]

Use this theorem to solve for the missing values in the table as labeled "Ex: 5."
