On december 24, 1924, the temperature in fairfield, montana, fell from 63f at noon to -21f at midnight. what was the average temperature change per hour?

Average temperature change can be found through the equation

Avg Temp change per hour=Total temperature change ÷ Total time

=84÷12

=7

Since the temperature was decreasing, make the 7 negative -7

Hope this helps!

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
