Understanding the Problem

Siera has calculated her hometown's average high temperature in degrees Fahrenheit for a month. Now, she wants to convert this temperature from degrees Fahrenheit to degrees Celsius using the given function $C(F)=\frac{5}{9}(F-32)$ . In this article, we will explore the process of converting temperature from Fahrenheit to Celsius and understand the significance of the given function.

The Fahrenheit to Celsius Conversion Function

The given function $C(F)=\frac{5}{9}(F-32)$ is a mathematical representation of the process of converting temperature from Fahrenheit to Celsius. This function takes the temperature in degrees Fahrenheit as input and returns the equivalent temperature in degrees Celsius.

To understand how this function works, let's break it down into its components:

Temperature difference: The function first calculates the difference between the input temperature in Fahrenheit and 32 degrees Fahrenheit. This difference represents the number of degrees by which the temperature in Fahrenheit is higher than 32 degrees Fahrenheit.
Scaling factor: The function then multiplies this temperature difference by a scaling factor of $\frac{5}{9}$ . This scaling factor is used to convert the temperature difference from Fahrenheit to Celsius.
Celsius temperature: Finally, the function adds the result of the multiplication to 32 degrees Celsius to obtain the equivalent temperature in degrees Celsius.

Step-by-Step Conversion Process

To convert a temperature from Fahrenheit to Celsius using the given function, we can follow these steps:

Calculate the temperature difference: Subtract 32 from the input temperature in Fahrenheit to obtain the temperature difference.
Apply the scaling factor: Multiply the temperature difference by the scaling factor of $\frac{5}{9}$ .
Add 32 degrees Celsius: Add 32 degrees Celsius to the result of the multiplication to obtain the equivalent temperature in degrees Celsius.

Example: Converting 80°F to Celsius

Let's use the given function to convert 80°F to Celsius.

Calculate the temperature difference: $80 - 32 = 48$
Apply the scaling factor: $\frac{5}{9} \times 48 = 26.67$
Add 32 degrees Celsius: $26.67 + 32 = 58.67°C$

Therefore, the equivalent temperature of 80°F in Celsius is 58.67°C.

Conclusion

In this article, we have explored the process of converting temperature from Fahrenheit to Celsius using the given function $C(F)=\frac{5}{9}(F-32)$ . We have also seen how to apply this function to convert a temperature from Fahrenheit to Celsius using a step-by-step process. By understanding this function and the conversion process, we can easily convert temperatures between Fahrenheit and Celsius.
