Final answer:
The correct function for converting temperature from Kelvin to Fahrenheit is F(k) = (1.8 × (k - 273.15)) + 32, by combining the individual conversions from Kelvin to Celsius and then Celsius to Fahrenheit.
Step-by-step explanation:
To convert temperature from Kelvin to Fahrenheit, you need the right conversion function that incorporates both conversions: from Kelvin to Celsius, and from Celsius to Fahrenheit. The given function to convert temperature from Kelvin to Celsius is C(k) = k - 273.15. We also have the function to convert Celsius to Fahrenheit, which is F(°C) = (1.8 × °C) + 32.
Combining these two functions, we get the Kelvin to Fahrenheit conversion function by substituting the Kelvin to Celsius conversion into the Celsius to Fahrenheit formula:
-
- First, convert Kelvin to Celsius: C(k) = k - 273.15.
-
- Next, convert Celsius to Fahrenheit: F(°C) = (1.8 × °C) + 32.
-
- Combine the two: F(k) = (1.8 × (k - 273.15)) + 32.
Therefore, the correct function for converting temperature from Kelvin to Fahrenheit is F(k) = (1.8 × (k - 273.15)) + 32.
