A cup of hot coffee has been left to cool in a room with an ambient temperature of 21C.

The relationship between the elapsed time, m, in minutes, since the coffee was left to cool, and the temperature of the coffee, T, measured in C ∘, is modeled by the following function.

T(m)=21+74*10^-0.03m

What will the temperature of the coffee be after 10 minutes?

Round your answer, if necessary, to the nearest hundredth.

Thank you!! WORTH 50 PNTS!!

Answer:

58.09 degrees C.

Explanation:

T(m)=21+74*10^-0.03m

When m = 10 minutes:

T(10) = 21 + 74*10^(-0.03*10)

= 21 + 74*10^(-0.3)

= 58.0879
