Power from a Wind Turbine The power produced by a wind turbine depends on the speed of the wind. If a windmill has blades 3 meters long, then the power $P$ produced by the turbine is modeled by $$ P(v)=14.1 v^{3} $$ where $P$ is measured in watts $(\mathrm{W})$ and $v$ is measured in meters per second $(\mathrm{m} / \mathrm{s}) .$ Graph the function $P$ for wind speeds between 1 $\mathrm{m} / \mathrm{s}$ and 10 $\mathrm{m} / \mathrm{s}$ .

Key Concepts

Function Domain

The domain of a function describes the set of input values for which the function is defined. Determining the appropriate domain is crucial in real-world applications to ensure that the mathematical model is applied within practical limits.

Mathematical Modeling

Mathematical modeling involves creating a function or equation to represent real-world phenomena. In this context, it is used to simulate the relationship between wind speed and power output, enabling further analysis and predictions about the system’s behavior.

Graphing Functions

Graphing functions is the process of visually plotting the mathematical relationship on a coordinate system. This helps in understanding how the output variable changes with the input, identifying trends and key points such as rapid increases due to nonlinear dependencies.

Power Functions

Power functions, where a variable is raised to an exponent, capture relationships where changes in the input lead to scaled, often nonlinear, changes in the output. The cubic relationship here indicates that the power output increases significantly as the wind speed increases.
