Math Problem Statement

d varies directly with the square of w and inversely with p. Use k as the constant of proportionality.

Solution

The given problem states:

  • dd varies directly with the square of ww
  • dd varies inversely with pp
  • kk is the constant of proportionality

Using these conditions, the mathematical expression can be written as:

d=kw2pd = k \cdot \frac{w^2}{p}

This equation reflects the direct relationship of dd with w2w^2 and the inverse relationship with pp, with kk as the constant of proportionality.

Do you want more details or have any questions?

Here are 5 related questions:

  1. What happens to dd when ww is doubled, keeping pp constant?
  2. How does dd change if pp is halved, but ww remains the same?
  3. Can you derive the constant kk if values for dd, ww, and pp are provided?
  4. What are examples of real-life scenarios where direct and inverse variation occur together?
  5. How would the equation change if dd varied directly with ww (not w2w^2)?

Tip: Direct variation means multiplying the independent variable, while inverse variation means dividing by the independent variable.
