![### Vector Field Analysis Using Green's Theorem
#### Problem Statement
Consider the following region \( R \) and the vector field \( \mathbf{F} \):
1. **Compute the two-dimensional divergence of the vector field.**
2. **Evaluate both integrals in the flux form of Green's Theorem and check for consistency.**
3. **Determine whether the vector field is source-free.**
Given:
\[ \mathbf{F} = (2xy, 9x^2 - y^2) \]
\[ R \text{ is the region bounded by } y = x(6-x) \text{ and } y = 0. \]
#### Steps and Calculations
**a. The two-dimensional divergence is:**
\[ \nabla \cdot \mathbf{F} = \_\_\_\_ \]
**b. Set up the integral over the region:**
\[
\int \int_R \_\_\_\_ \, dy \, dx
\]
**Set up the line integral for the \( y = x(6 - x) \) boundary:**
\[
\int_0^6 \_\_\_\_ \, dt
\]
**Set up the line integral for the \( y = 0 \) boundary:**
\[
\int_0^6 \_\_\_\_ \, dt
\]
**Evaluate these integrals and check for consistency:**
Select the correct choice below and fill in any answer boxes to complete your choice:
**A.** The integrals are consistent because they all evaluate to \_\_\_\_.
**B.** The integrals are not consistent because the integral over \( R \) evaluates to \_\_\_\_, while the line integrals evaluate to \_\_\_\_.
**c. Is the vector field source-free?**
---
### Guidance
To evaluate the divergence:
\[ \nabla \cdot \mathbf{F} = \frac{\partial (2xy)}{\partial x} + \frac{\partial (9x^2 - y^2)}{\partial y} \]
Set up the double integral accordingly:
\[ \int_{0}^{6} \int_{0}^{x(6-x)} (\nabla \cdot \mathbf{F}) \, dy \, dx \]
For the line integrals, parameterize the boundaries and integrate \( \mathbf{F} \](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdf012473-cbdd-4844-9f9c-11a895f96b45%2Ff3a2bc2c-5c9b-4bc1-9d78-04d8aefd707d%2Fiuno77h_processed.jpeg&w=3840&q=75)

![**Integral Consistency Evaluation**
Evaluate these integrals and check for consistency. Select the correct choice below and fill in any answer boxes to complete your choice.
1. **Evaluate the Integrals**
Choose one of the following:
- \( \bigcirc \) **A.** The integrals are consistent because they all evaluate to \(\_\_\_\_\_\).
- \( \bigcirc \) **B.** The integrals are not consistent because the integral over \( R \) evaluates to \(\_\_\_\_\_\) while the line integrals evaluate to \(\_\_\_\_\_\).
2. **Is the Vector Field Source-Free?**
Choose one of the following:
- \( \bigcirc \) **A.** Yes, because the two-dimensional divergence is zero everywhere.
- \( \bigcirc \) **B.** No, because the flux is zero only for the given region.
- \( \bigcirc \) **C.** Yes, because the flux is zero for the given region.
- \( \bigcirc \) **D.** No, because the two-dimensional divergence is not zero everywhere.
This assessment requires the student to evaluate given integrals to determine their consistency and analyze the source-free nature of a vector field based on the divergence.
