Question
**Using the Chain Rule to Find Derivatives**

**Objective:**
To use the chain rule to find the derivatives \(\frac{dz}{ds}\) and \(\frac{dz}{dt}\).

**Given:**

- You must demonstrate in your work that you are using the chain rule.

- Equations:
  \[
  z = x^2y + tx
  \]
  \[
  x = s^2 + 3t
  \]
  \[
  y = 25 - t
  \]

**Instructions:**

1. Identify the variables and their relationships:
   - \(z\) is a function of \(x\), \(y\), and \(t\).
   - \(x\) is a function of \(s\) and \(t\).
   - \(y\) is a function of \(t\).

2. Apply the chain rule:
   - Differentiate \(z\) with respect to \(s\) and \(t\) by using the chain rule to incorporate the dependence of \(z\) on \(x\), \(y\), and directly on \(t\).

3. For \(\frac{dz}{ds}\), consider how \(x\) and thus \(z\) changes with \(s\).

4. For \(\frac{dz}{dt}\), account for the changes in \(x\), \(y\), and \(t\).

**Note:**
Organize your work clearly to demonstrate the use of the chain rule in obtaining derivatives.
