Answer:
The difference between the vehicles is 0,009 gallons per mile.
Step-by-step explanation:
To know the difference between the vehicles in gallons per mile we need to obtain this information for each car:
-Sam´s van
Gallons per mile: 9 gallons/208.8 miles
Gallons per mile: 0.0431
-Hasan´s small car:
Gallons per mile: 8 gallons/234.4 miles
Gallons per mile: 0.0341
The difference between the vehicles is:
0.0431-0.0341= 0,009 gallons per mile
Answer:
-3
Step-by-step explanation:
If we directly evaluate the function at -1, we get 0/0, meaning we may still have a limit to find.
In this case, factoring the polynomial at the top would be helpful.
The polynomial can be factored to (x+1)(x-2), so the function would now turn out to be (x+1)(x-2)/(x+1)
The (x+1) cancel out, leaving you with (x-2), which you can directly evaluate by plugging in x as -1:
-1-2 = -3
Quick disclaimer: the function is still undefined at -1; it's just that the function gets closer and closer to -3 as you approach -1.
I hope this helped you.
