Find the mathematical model for the following statement. Remember to use k as the constant of proportionality.

z varies jointly as the 4th power of x and the 5th power of y.

The mathematical model for the given statement "z varies jointly as the 4th power of x and the 5th power of y" can be written as:

\[
z = kx^4y^5
\]

where:
- \( z \) is the dependent variable,
- \( x \) and \( y \) are the independent variables,
- \( k \) is the constant of proportionality.

Would you like a more detailed explanation or have any other questions?

Here are 5 related questions:
1. How does changing \( x \) affect \( z \) in this model?
2. What happens to \( z \) if both \( x \) and \( y \) are doubled?
3. Can you solve for \( k \) if you know specific values for \( z \), \( x \), and \( y \)?
4. What would the model look like if \( z \) varies inversely with \( y^5 \)?
5. How can this equation be used in real-life applications?

**Tip:** In joint variation problems, the dependent variable changes when two or more variables affect it simultaneously, usually with a constant of proportionality.
