### Matching Points in Polar Coordinates This educational exercise involves matching a given point in polar coordinates to the correct point on a Cartesian graph. The problem provides the polar coordinates: \[ \left( -2, \frac{5\pi}{6} \right) \] ### Instruction: Match the point in polar coordinates with either A, B, C, or D on the graph. ### Graph Description: The graph is a Cartesian coordinate system with both the x-axis and y-axis clearly marked with positive and negative values. The axes are labeled as follows: - The x-axis ranges from -3 to 3. - The y-axis ranges from -3 to 3. ### Labeled Points on Graph: - **Point A** is located at Cartesian coordinates (3, 0). - **Point B** is located at Cartesian coordinates (0, 3). - **Point C** is located at Cartesian coordinates (-3, 0). - **Point D** is located at Cartesian coordinates (0, -3). ### Objective: Using the given polar coordinates \(\left( -2, \frac{5\pi}{6} \right)\), identify the corresponding point (A, B, C, or D) on the Cartesian coordinate system. To convert polar coordinates to Cartesian coordinates: \[ x = r \cos(\theta) \] \[ y = r \sin(\theta) \] #### Step-by-Step Conversion: 1. \( r = -2 \) 2. \( \theta = \frac{5\pi}{6} \) Calculate \( x \) and \( y \): \[ x = -2 \cos\left(\frac{5\pi}{6}\right) \] \[ y = -2 \sin\left(\frac{5\pi}{6}\right) \] Hence, by determining x and y values from the conversion, you can match the Cartesian coordinates to one of the labeled points A, B, C, or D on the graph.

Question
### Matching Points in Polar Coordinates

This educational exercise involves matching a given point in polar coordinates to the correct point on a Cartesian graph. 

The problem provides the polar coordinates:

\[ \left( -2, \frac{5\pi}{6} \right) \]

### Instruction:
Match the point in polar coordinates with either A, B, C, or D on the graph.

### Graph Description:
The graph is a Cartesian coordinate system with both the x-axis and y-axis clearly marked with positive and negative values. The axes are labeled as follows:

- The x-axis ranges from -3 to 3.
- The y-axis ranges from -3 to 3.

### Labeled Points on Graph:

- **Point A** is located at Cartesian coordinates (3, 0).
- **Point B** is located at Cartesian coordinates (0, 3).
- **Point C** is located at Cartesian coordinates (-3, 0).
- **Point D** is located at Cartesian coordinates (0, -3).

### Objective:
Using the given polar coordinates \(\left( -2, \frac{5\pi}{6} \right)\), identify the corresponding point (A, B, C, or D) on the Cartesian coordinate system.

To convert polar coordinates to Cartesian coordinates:

\[ x = r \cos(\theta) \]
\[ y = r \sin(\theta) \]

#### Step-by-Step Conversion:
1. \( r = -2 \)
2. \( \theta = \frac{5\pi}{6} \)

Calculate \( x \) and \( y \):

\[ x = -2 \cos\left(\frac{5\pi}{6}\right) \]
\[ y = -2 \sin\left(\frac{5\pi}{6}\right) \]

Hence, by determining x and y values from the conversion, you can match the Cartesian coordinates to one of the labeled points A, B, C, or D on the graph.
