On his first day of school, Kareem found the high temperature in degrees Fahrenheit to be [tex]$76.1^{\circ}$[/tex]. He plans to use the function [tex]$C(F)=\frac{5}{9}(F-32)$[/tex] to convert this temperature from degrees Fahrenheit to degrees Celsius.

What does [tex]$C(76.1)$[/tex] represent?

A. The temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.
B. The temperature of 76.1 degrees Celsius converted to degrees Fahrenheit.
C. The amount of time it takes for a temperature of 76.1 degrees Fahrenheit to be converted to 32 degrees Celsius.
D. The amount of time it takes for a temperature of 76.1 degrees Celsius to be converted to 32 degrees Fahrenheit.

Answer :

To answer the question about what [tex]\( C(76.1) \)[/tex] represents, we need to understand what the function [tex]\( C(F) = \frac{5}{9}(F-32) \)[/tex] does. This function is used to convert temperatures from degrees Fahrenheit to degrees Celsius.

Here's how it works:

1. Identify the Input: The input for the function is given as 76.1 degrees Fahrenheit. So, we need to find what [tex]\( C(76.1) \)[/tex] represents.

2. Apply the Function: Substitute [tex]\( F = 76.1 \)[/tex] into the function:
[tex]\[
C(76.1) = \frac{5}{9}(76.1 - 32)
\][/tex]

3. Calculate the Difference:
- First, subtract 32 from 76.1:
[tex]\[
76.1 - 32 = 44.1
\][/tex]

4. Apply the Conversion Factor:
- Multiply the result by [tex]\(\frac{5}{9}\)[/tex] to convert it to Celsius:
[tex]\[
C = \frac{5}{9} \times 44.1 \approx 24.5
\][/tex]

Therefore, [tex]\( C(76.1) \)[/tex] represents the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius, which is approximately 24.5 degrees Celsius.

Given this explanation, the correct choice from the options provided is:
- The temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.
