Question 797774: The gas tank on a typical mid-sized import SUV is 20 gallons, If a reasonable driver averages 22 miles per gallon, answer the following questions about the gasoline left in the tank (G) and the miles driven (d)
1. If a function is developed to model the amount of gas left in the tank, what is the slope of this function?
2. what mathematical term is used to describe the number 20 from the above problem?
3. what is the problem domain?
4. What function can be used to model the gas left in the tank at miles driven?
5. Using your model, what is the zero? what is the physical significance of zero?
6. How much gasoline is left after driving 300 miles?
7. if 6.5 gallons of gasoline are left in the tank, how far has the car been driven?
8. what is the model for gasoline left in the tank if the driver gets 27 mpg?
9. what is the problem domain at 27 mpg?
10. at 27 mpg, what is the zero of the model? Answer by solver91311(24713) (Show Source):
I'm not going to do your entire 10 question homework assignment.
1. If the car hasn't moved since it was filled with 22 gallons of gas, then and . But when the gas is gone (), at 22 mpg, the car must have gone 440 miles (20 times 22). That gives two points on the plane, namely and .
Use the two point form of an equation of a line:
where and are the coordinates of the given points.
