MATHEMATICAL EQUATION OF VARIATION

A. Express the following as an equation where k is the constant of variation.

1. The circumference (C) of a circle varies directly as the length of its diameter (d).

2. The number of slices (s) that can be made from a standard Pinoy loaf of bread is inversely proportional to the thickness (t) of a slice.

  • [tex] \sf \color{darkblue}{s = \frac{k}{t} }[/tex]

3. s varies jointly as r and t

  • [tex] \sf \color{darkblue}{s = krt }[/tex]

4. V varies jointly as I, w, and h

  • [tex]\sf \color{darkblue}{V = klwh }[/tex]
