What is the expected temperature change? C. If the temperature actually changes by 5 degrees more than predicted, what will be the change in temperature?

Respuesta :

Answer:

A. [tex]Change = Final\ temperature - Inicial\ temperature[/tex]

B. Negative change of 18 degrees

C. Negative change of 23 degrees, final temperature would be -8°F

Step-by-step explanation:

A.

The expression that represents the change in temperature is:

[tex]Change = Final\ temperature - Inicial\ temperature[/tex]

B.

If the final temperature is -3°F and the inicial temperature is 15°F, the change in temperature is:

[tex]Change = -3 - 15 = -18\° F[/tex]

We have an absolute change of 18 degrees.

C.

If the change is 5 degrees more, the change would be 18 + 5 = 23 degrees, and the final temperature would be 5 degrees lower, that is:

[tex]Final\ temperature = -3 - 5 = -8\°F[/tex]
