Considering that the car does 50 miles per gallon, the linear function for the number of gallons of fuel in Jim's fuel tank, n, in terms of the number of miles x that Jim has driven since filling his tank is given by:
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- Jim's car holds 14 gallons of fuel, hence
.
- Considering it does 50 miles per gallon, and the amount in the tank will decrease, the slope is
.
Hence, the function is:

Every point in the unit circle is identified either by its coordinates or by the angle it forms with the x-axis,
.
The trigonometric functions associate with every angle and the correspondant
coordinates the two values
This procedure can be done for every angle , so you don't have to work with acute angles only.
