A heated 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?
2 answers:
Answer: 56
Given: c(x) + h(x) = temperature, find the value when x = 5
Step by Step: c(x) + h(x) = - x - 3
=
=
=
=
=
= 56
Answer:
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
