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

Answer :

To solve this problem, we are using a function to convert temperature from degrees Fahrenheit to degrees Celsius. The function provided is [tex]\( C(A) = \frac{5}{9}(F - 32) \)[/tex].

In this case, we are given a temperature of 76.1 degrees Fahrenheit. Our goal is to find what this temperature is in degrees Celsius.

Here's how you can understand it:

1. Identify the Known Temperature:
- We have a temperature in Fahrenheit: [tex]\( F = 76.1 \)[/tex].

2. Apply the Conversion Formula:
- The conversion formula is used to convert Fahrenheit to Celsius:
[tex]\[ C = \frac{5}{9}(F - 32) \][/tex]

3. Substitute the Fahrenheit Temperature:
- Substitute [tex]\( F = 76.1 \)[/tex] into the formula:
[tex]\[ C = \frac{5}{9}(76.1 - 32) \][/tex]

4. Calculate the Difference:
- First, calculate the difference between 76.1 and 32:
[tex]\[ 76.1 - 32 = 44.1 \][/tex]

5. Multiply by [tex]\(\frac{5}{9}\)[/tex]:
- Now, multiply the result by [tex]\(\frac{5}{9}\)[/tex]:
[tex]\[ C = \frac{5}{9} \times 44.1 \][/tex]

6. Find the Celsius Temperature:
- This calculation gives us the Celsius temperature, which is approximately 24.5 degrees Celsius.

Thus, the value [tex]\( C(76.1) \)[/tex] represents the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius. This conversion results in approximately 24.5 degrees Celsius.

So, the correct interpretation of [tex]\( C(76.1) \)[/tex] is:

- The temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.
