Introduction

As a dog owner, Nora wants to create a safe and enjoyable space for her dog, Max, to run around in the backyard. With a perimeter of 120 feet, she has enough materials to create a dog run. However, she needs to determine the optimal dimensions of the run to ensure that Max has enough space to move around comfortably. In this article, we will explore the mathematical approach to designing the perfect dog run.

Understanding the Problem

The problem is represented by the function $A = -w^2 + 60w$ , where $A$ is the area of the run and $w$ is the width of the run. The function is quadratic, meaning that the area of the run is a quadratic function of the width. To find the optimal dimensions of the run, we need to maximize the area of the run.

Maximizing the Area of the Run

To maximize the area of the run, we need to find the critical points of the function. Critical points occur when the derivative of the function is equal to zero. Let's find the derivative of the function:

\frac{dA}{dw} = -2w + 60

Now, we set the derivative equal to zero and solve for $w$ :

-2w + 60 = 0

w = 30

So, the critical point occurs when the width of the run is 30 feet.

Second Derivative Test

To determine whether the critical point is a maximum or a minimum, we need to use the second derivative test. The second derivative of the function is:

\frac{d^2A}{dw^2} = -2

Since the second derivative is negative, the critical point is a maximum.

Optimal Dimensions of the Run

Based on the analysis, the optimal dimensions of the run are:

Width: 30 feet
Length: 120 - 2(30) = 60 feet

Conclusion

In this article, we explored the mathematical approach to designing the perfect dog run. By maximizing the area of the run, we determined the optimal dimensions of the run. The optimal dimensions are a width of 30 feet and a length of 60 feet. This will provide Max with enough space to move around comfortably and enjoy his time in the backyard.
