**Question:**
An jet is flying on a bearing of 338° at 420 miles per hour. Find the component form of the velocity of the jet. Round your decimal to two places.

**Solution:**
To solve for the component form of the velocity of the jet, we need to break down the given velocity into its Cartesian components. The bearing of 338° is measured clockwise from the north. 

1. **Convert the Bearing:**
   The bearing of 338° can be converted to standard position angle from the positive x-axis (East):
   - Standard position angle = 450° - bearing = 450° - 338° = 112°.

2. **Velocity Components (Vx and Vy):**
   - Vx = V * cos(112°)
   - Vy = V * sin(112°)

3. **Calculate the Components:**
   Given V = 420 mph:
   - Vx = 420 * cos(112°)
   - Vy = 420 * sin(112°)

4. **Evaluate the Trigonometric Functions:**
   Using trigonometric values:
   - cos(112°) ≈ -0.3746
   - sin(112°) ≈ 0.9272

5. **Final Calculations:**
   - Vx = 420 * (-0.3746) ≈ -157.53 mph
   - Vy = 420 * (0.9272) ≈ 389.42 mph

Thus, the component form of the velocity is approximately:
\[ \mathbf{V} = (-157.53 \, \text{mph}, 389.42 \, \text{mph}) \]

**Answer:**
The component form of the velocity of the jet is approximately \((-157.53, 389.42)\) when rounded to two decimal places.
