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
Apply the slope formula as follows:
5-4 1
m = --------- = ---------
7-(-3) 10
Answer:
2.66216x10^20
Step-by-step explanation:
That would be the transitive property
So basically find 77% of the 22000 and then subtract that answer from 22000
