Question

Transcribed Image Text:**Vectors Subtraction and Scalar Multiplication**
In this instructional guide, we will analyze the graphical representation of vectors and learn about their operations, such as subtraction and scalar multiplication.
**Graph Description:**
In the provided graph, vectors \( \mathbf{u} \) and \( \mathbf{v} \) are illustrated in a 2-dimensional coordinate plane.
- The horizontal axis represents the x-axis, while the vertical axis indicates the y-axis.
- The coordinate system ranges from -10 to 10 on both axes.
**Vector \( \mathbf{u} \):**
- Vector \( \mathbf{u} \) starts at the origin (0, 0) and terminates at the point (-5, -5).
- It is directed towards the third quadrant, pointing downwards and to the left.
**Vector \( \mathbf{v} \):**
- Vector \( \mathbf{v} \) starts at the origin (0, 0) and terminates at the point (7, 5).
- It is directed towards the first quadrant, pointing upwards and to the right.
**Question:**
What is \(-3(\mathbf{u} - \mathbf{v})\)?
**Operation Explanation:**
To find the vector resulting from \(-3(\mathbf{u} - \mathbf{v})\), follow these steps:
1. **Vector Subtraction (\(\mathbf{u} - \mathbf{v}\)):**
- \(\mathbf{u} = <-5, -5>\)
- \(\mathbf{v} = <7, 5>\)
- \(\mathbf{u} - \mathbf{v} = <-5, -5> - <7, 5> = <-5 - 7, -5 - 5> = <-12, -10>\)
2. **Scalar Multiplication (\(-3(\mathbf{u} - \mathbf{v})\)):**
- Multiply the resulting vector by -3:
- \(-3(\mathbf{u} - \mathbf{v}) = -3<-12, -10> = <36, 30>\)
Thus, the vector \(\-3(\mathbf{u} - \mathbf{v})\) is \(<36, 30>\).
**Conclusion:**
Understanding these operations, vector subtraction, and scalar multiplication can help apply these concepts to various fields such as physics
