Final answer:
The statement can be written as the power function h = ks, where h represents the altitude of an equilateral triangle and s represents one side of the triangle.
Step-by-step explanation:
The statement can be written as the power function h = ks, where h represents the altitude of an equilateral triangle and s represents one side of the triangle. Since the altitude varies directly with the side length, we can express this relationship as a power function. The constant of variation, k, represents the proportionality constant between the altitude and the side length.
