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 :

Sure! Let's go through the problem step-by-step to understand what [tex]\(C(76.1)\)[/tex] represents.

You are given a function [tex]\(C(F) = \frac{5}{9}(F - 32)\)[/tex] which converts a temperature from degrees Fahrenheit ([tex]\(F\)[/tex]) to degrees Celsius ([tex]\(C\)[/tex]).

The problem states that Kareem found the high temperature on his first day of school to be [tex]\(76.1^\circ\)[/tex] Fahrenheit, and he wants to convert this temperature to degrees Celsius.

Let's break it down:

1. Identify the given Fahrenheit temperature:
[tex]\[
F = 76.1^\circ \text{F}
\][/tex]

2. Using the conversion function [tex]\(C(F)\)[/tex]:
[tex]\[
C(76.1) = \frac{5}{9}(76.1 - 32)
\][/tex]

3. Compute the inside of the parentheses first:
[tex]\[
76.1 - 32 = 44.1
\][/tex]

4. Apply the remaining part of the function:
[tex]\[
C(76.1) = \frac{5}{9} \times 44.1
\][/tex]

5. Multiply:
[tex]\[
C(76.1) = \frac{5 \times 44.1}{9} \approx 24.5^\circ \text{C}
\][/tex]

So, [tex]\(C(76.1)\)[/tex] represents the temperature of [tex]\(76.1^\circ\)[/tex] Fahrenheit converted to degrees Celsius, which equals approximately [tex]\(24.5^\circ\)[/tex] Celsius.

Therefore, the correct answer is:
- [tex]\(C(76.1)\)[/tex] represents the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.
