**Problem Statement:** 4. Let the function \( v(t) = \frac{6 \sqrt[3]{t}}{4t + 1} \) be the volume, in cm\(^3\), of a balloon at time \( t \), in seconds. At what rate is the volume of the balloon changing with respect to time when \( t = 8 \)? Is the balloon inflating or deflating at this time? **Explanation:** - The function \( v(t) \) represents the volume of the balloon in cubic centimeters as a function of time \( t \) in seconds. - To determine the rate at which the volume is changing, calculate the derivative of \( v(t) \) with respect to \( t \), denoted as \( v'(t) \). - Evaluate \( v'(t) \) at \( t = 8 \). - The sign of \( v'(8) \) will indicate whether the balloon is inflating (positive rate) or deflating (negative rate) at \( t = 8 \).

**Problem Statement:**

4. Let the function \( v(t) = \frac{6 \sqrt[3]{t}}{4t + 1} \) be the volume, in cm\(^3\), of a balloon at time \( t \), in seconds. At what rate is the volume of the balloon changing with respect to time when \( t = 8 \)? Is the balloon inflating or deflating at this time?

**Explanation:**

- The function \( v(t) \) represents the volume of the balloon in cubic centimeters as a function of time \( t \) in seconds.
- To determine the rate at which the volume is changing, calculate the derivative of \( v(t) \) with respect to \( t \), denoted as \( v'(t) \).
- Evaluate \( v'(t) \) at \( t = 8 \).
- The sign of \( v'(8) \) will indicate whether the balloon is inflating (positive rate) or deflating (negative rate) at \( t = 8 \).
