The problem you're working on involves population growth described by the **logistic equation**. The key details provided are:

- Growth constant \( k = 0.69 \)
- Carrying capacity of the forest \( K = 10,000 \) deer
- Initial population \( P_0 = 7,000 \) deer

The logistic growth equation is typically modeled by:

\[
P(t) = \frac{K}{1 + \left( \frac{K - P_0}{P_0} \right) e^{-k t}}
\]

However, since we are only looking for the population after one breeding season (i.e., after \( t = 1 \)), we can plug in the values and solve for the population at \( t = 1 \).

Let's break down the process:

1. **Initial equation for \( t = 1 \)**:

\[
P(1) = \frac{10,000}{1 + \left( \frac{10,000 - 7,000}{7,000} \right) e^{-0.69 \cdot 1}}
\]

2. Simplifying the equation:

\[
P(1) = \frac{10,000}{1 + \left( \frac{3,000}{7,000} \right) e^{-0.69}}
\]

Now we can calculate the values step by step.

- \( \frac{3,000}{7,000} = 0.4286 \)
- \( e^{-0.69} \approx 0.5012 \)
- \( 0.4286 \times 0.5012 = 0.2148 \)
- \( 1 + 0.2148 = 1.2148 \)

Now the equation becomes:

\[
P(1) = \frac{10,000}{1.2148} \approx 8,233 \text{ deer}
\]

Thus, the population after one breeding season would be approximately **8,233** deer.

### 5 related questions:
1. What factors can affect the accuracy of the logistic growth model in real-life populations?
2. How does the value of \( k \) (growth rate) influence the speed at which the population approaches the carrying capacity?
3. How would the population change if the initial population were above the carrying capacity?
4. Can you describe scenarios where logistic growth would not be an appropriate model for population growth?
5. How is the concept of carrying capacity used in conservation efforts?

### Tip:
When using exponential models, always double-check the growth constant \( k \) and ensure it's applied in the correct units (e.g., per year, per season, etc.).

Assume there is a certain population of deer in a forest whose growth is described by the logistic equation. The constant of proportionality for this type of deer is k = 0.69, and the carrying capacity of the forest is 10,000 deer. If the starting population is 7,000 deer, then after one breeding season the population of the forest is ______.

Explore how to calculate the population of deer in a forest using the logistic growth equation. With a starting population of 7,000 deer, a proportionality constant of 0.69, and a carrying capacity of 10,000, find the population after one breeding season. Suitable for students in Grades 10-12.
