Answer:
It is an exponential function
Step-by-step explanation:
With every growing value of x, it will multiply itself that many number of times.
 
        
             
        
        
        
40/x = 40/x+5 + 2/60
-> i don’t have a sketchbook or calculator at the moment so pls figure out the final answer yourself
        
             
        
        
        
Answer: it is a direct variation.
Justification:
In a direct variation the variables are related by a proportionality constant in this way:
y = k x
Tthan means that the value of y is always the product of a constant times the value of x.
The situation discribed for the coal may be written as:
number of tons of coal burned: c
number of hours: h
⇒ c = k × h
Which is that you can calcualte the number of tons of coal burned at any time, once you know the proportionality constant k.
