**MODELING WITH MATHEMATICS**

The Art of Modeling Real-World Phenomena with Mathematics

Mathematics is a powerful tool for modeling real-world phenomena. It allows us to describe complex systems, make predictions, and understand the underlying mechanisms that govern their behavior. In this article, we will explore the concept of modeling with mathematics, using the example of a kicker punting a football.

The Problem

A kicker punts a football, and the height of the football is represented by the function $f(x)=-\frac{1}{9}(x-30)^2+25$ , where $x$ is the horizontal distance from the kicker's goal line. Our goal is to graph this function and understand its behavior.

Graphing the Function

To graph the function, we need to understand its components. The function is a quadratic function, which means it has a parabolic shape. The general form of a quadratic function is $f(x)=ax^2+bx+c$ , where $a$ , $b$ , and $c$ are constants.

In our case, the function is $f(x)=-\frac{1}{9}(x-30)^2+25$ . We can rewrite this function as $f(x)=-\frac{1}{9}(x^2-60x+900)+25$ , which is a quadratic function in the form $f(x)=ax^2+bx+c$ .

To graph the function, we need to find the vertex of the parabola. The vertex is the point on the parabola where the function reaches its maximum or minimum value. In this case, the vertex is the point where the function reaches its maximum value.

Finding the Vertex

To find the vertex, we need to find the x-coordinate of the vertex. The x-coordinate of the vertex is given by the formula $x=-\frac{b}{2a}$ . In our case, $a=-\frac{1}{9}$ and $b=-60$ .

Plugging these values into the formula, we get $x=-\frac{-60}{2(-\frac{1}{9})}$ . Simplifying this expression, we get $x=270$ .

The Vertex

The vertex is the point on the parabola where the function reaches its maximum value. In this case, the vertex is the point $(270, 25)$ .

Graphing the Function

Now that we have found the vertex, we can graph the function. The graph of the function is a parabola that opens downward. The vertex is the point $(270, 25)$ .

Understanding the Graph

The graph of the function represents the height of the football as a function of the horizontal distance from the kicker's goal line. The graph shows that the height of the football increases as the horizontal distance increases, reaches a maximum value at the vertex, and then decreases as the horizontal distance increases further.

Discussion

The graph of the function represents a real-world phenomenon, the flight of a football. The function models the height of the football as a function of the horizontal distance from the kicker's goal line.

The graph shows that the height of the football increases as the horizontal distance increases, reaches a maximum value at the vertex, and then decreases as the horizontal distance increases further. This is consistent with our intuitive understanding of the flight of a football.

Conclusion

In this article, we have explored the concept of modeling with mathematics, using the example of a kicker punting a football. We have graphed the function that represents the height of the football as a function of the horizontal distance from the kicker's goal line.
