The temperature of the rod was 10°C above zero. It was kept in a freezer at 2 p. m. If its temperature decreased at the rate of 3°C per minute, at what time would be the
temperature be 8°C below zero? What would be the temperature at 3 pm ?

I think it would take 6 minutes to reach temperature below 8 °C

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

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
