The equation below models the fuel economy E(s) in miles per gallon (mpg) of a certain vehicle as a function of constant vehicle speed s, in miles per hour. Based on the model, which of the following is the best interpretation of E(25)=24 in this context?
When the vehicle has a constant speed of 24mph, it's predicted fuel economy is 25 mpg.
When the vehicle has a constant speed of 25mph, it's predicted fuel economy is 24 mpg.
When the vehicle has constant speed of 25mph, it's predicted fuel economy is 55 mpg.
None of the given interpretations are correct.
The correct interpretation is:
When the vehicle has a constant speed of 25mph, its predicted fuel economy is 24 mpg.
To interpret the equation E(s) = 24 in this context, we need to understand the given equation. The equation is stating that the fuel economy E(s), measured in miles per gallon (mpg), is a function of the constant vehicle speed s, measured in miles per hour (mph).
Now, let's break down the equation E(25) = 24. This equation is referring to the fuel economy when the vehicle has a constant speed of 25 mph. The value 25 is the input or the constant vehicle speed, and the value 24 is the output or the predicted fuel economy.
Therefore, the best interpretation of E(25) = 24 in this context is: When the vehicle has a constant speed of 25 mph, it's predicted fuel economy is 24 mpg.
Based on the model, the best interpretation of E(25)=24 in this context is:
When the vehicle has a constant speed of 25mph, its predicted fuel economy is 24 mpg.
