Aheated piece of metal cools according to the function c(x) = (.5)^x − 11, where x is measured in hours. a device is added that aids in cooling according to the function h(x) = −x − 3. what will be the temperature of the metal after five hours?

The temperature of metal after five years =  -18.96875

Step-by-step explanation:

Given : Function

where x is measured in hours

Another function is added h(x)=-x-3

therefore, the resultant function f(x)=h(x)+c(x)

For x=5

Therefore, The temperature of metal after five years = -18.96875

answer is c.

hope you got it chief

idk what your asking for but the sum equals 13
