Pls help ASAP!!!!


The temperature in degrees Celsius (C) can be converted to degrees Fahrenheit (F) using the formula F(C)= 9/5 C+k, where k is a constant. Find k, if to C=−40ºC corresponds F=−40ºF.

Answer:   32

Step-by-step explanation:

[tex]F(C)=\dfrac{9}{5}C+k\\\\-40=\dfrac{9}{5}(-40)+k\\\\-40=9(-8)+k\\\\-40=-72+k\\\\.\quad32=k[/tex]

Answer:

k = 32

Step-by-step explanation:

To get the value of k from expression:

[tex]F(C) = \frac{9}{5}C +k[/tex]

for F = -40 and C = -40, then:

[tex]-40 = \frac{9}{5}(-40)+k[/tex]

[tex]k =-40+\frac{9}{5}.40[/tex]

[tex]k = 72 - 40[/tex]

[tex]k = 32[/tex]

therefore, k should be 32 to get these answers.
