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 :

Sure! Let's go through the solution step-by-step to understand what [tex]$C(76.1)$[/tex] represents:

1. Identify the Function and its Purpose:

Kareem is using a function to convert temperature from degrees Fahrenheit to degrees Celsius. The function given is:

[tex]\[
C(F) = \frac{5}{9}(F - 32)
\][/tex]

In this function, [tex]\( C(F) \)[/tex] represents the temperature in degrees Celsius after converting from degrees Fahrenheit, where [tex]\( F \)[/tex] is the temperature in Fahrenheit.

2. Substitute the Given Temperature:

We're given that the temperature in degrees Fahrenheit is [tex]\( 76.1 \)[/tex]. We need to use the function to convert this temperature to degrees Celsius. So, we substitute [tex]\( F = 76.1 \)[/tex] into the function:

[tex]\[
C(76.1) = \frac{5}{9}(76.1 - 32)
\][/tex]

3. Interpret the Result:

The expression [tex]\( \frac{5}{9}(76.1 - 32) \)[/tex] computes the temperature in degrees Celsius that corresponds to [tex]\( 76.1 \)[/tex] degrees Fahrenheit. After evaluating this expression, you find that:

- [tex]\( C(76.1) \)[/tex] is approximately [tex]\( 24.5 \)[/tex] degrees Celsius.

4. Conclusion:

Therefore, [tex]\( C(76.1) \)[/tex] represents the conversion of the temperature [tex]\( 76.1 \)[/tex] degrees Fahrenheit into degrees Celsius. The correct interpretation from the given options is:

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