It looks like you've uploaded images related to calculating wind chill in Excel. Based on what I see:

1. You need to use the formula: $\text{Wind Chill} (°F) = 35.74 + 0.6215T - 35.75S^{0.16} + 0.4275T S^{0.16}$ where T is temperature (°F) and S is wind speed (mph).

2. You'll enter the formula in cell C10 to calculate wind chill for given temperature and wind speed.

3. You'll create a 10×10 table in cells D17:M26 to compute wind chill for various temperatures and wind speeds.

4. Use absolute/mixed/relative cell references to ensure correct formula replication.

5. Finally, you'll create two charts:

   • A line chart for Wind Chill as a function of Temperature at 13°F.
   • A clustered column chart for Wind Chill as a function of Wind Speed at 9 mph.

Would you like help writing the correct Excel formula for cell references?

Here are five questions to deepen your understanding:

1. How do absolute and relative cell references affect formula replication?
2. How can mixed references be useful in a 10×10 table?
3. What are the key differences between a line chart and a column chart?
4. How does wind chill vary with temperature and wind speed?
5. Why does the formula not work for a wind speed of 0 mph?
