This chain of inequalities forms the foundation for many other classical inequalities. See how the four common "means" - arithmetic, geometric, harmonic, and quadratic - relate to each other.

What is the minimum possible perimeter of a rectangle with area 25?

If \( x^2 + y^2 = 1, \) find the maximum value of \( (x + y)^2. \)

Suppose \( g(x) \) is positive for all \( x \). Determine the minimum value of

\[ f(x) = \frac{16 (g(x))^2 + 1}{g(x)}. \]
