The image shows a plot of "Pressure vs. Volume" with a power fit equation given as:

\[
y = A \cdot x^B
\]
where:
- \( A = 843.93 \)
- \( B = -0.92683 \)

The pressure (\(y\)) is expressed in kPa, and the volume (\(x\)) is expressed in mL.

To calculate the pressure at 7.0 mL, we can substitute \(x = 7.0\) into the equation:

\[
y = 843.93 \cdot (7.0)^{-0.92683}
\]

Let me calculate that.The pressure at a volume of 7.0 mL is approximately \(139.01 \, \text{kPa}\).

Would you like more details or have any other questions?

Here are five related questions:
1. How does the exponent \( B = -0.92683 \) affect the relationship between pressure and volume?
2. How does the value of the constant \( A = 843.93 \) influence the curve?
3. What is the physical significance of a power-law relationship in this context?
4. How can you calculate pressure for other volumes using this equation?
5. What is the role of the RMSE value in assessing the fit of this curve?

**Tip:** A negative exponent in power functions indicates an inverse relationship between the variables.

Learn how to calculate pressure at a volume of 7.0 mL using the power fit equation y = A * x^B. This example uses specific values (A = 843.93, B = -0.92683) to show how pressure changes with volume. Suitable for high school students studying physics or algebra.
