Answer:
The total displacement of the car is 2 meters south
Explanation:
As the car went south 10m, and then went back over it initial path for 8 meters, the actual distance registered in the car's odometer will be 18 m, but as far as vector displacement in its final position, this will be 2 meters south (10m -8m=2m).
Notice that the displacement vector is defined as the final position minus the initial position, which gives a distance of 2 from the origin, in the suoth direction.meters
Answer:
6
Explanation:
The rate of change in this scenario corresponds to the number of inches that Ree grows every year. Basically, Ree's height can be written as a linear equation as follows:

where
x is the number of years after the first birthday
y is the height in inches
q = 27 is the height of Ree on her first birthday
m = 6 is the inches gained by Ree at each birthday
So the equation can also be rewritten as
y = 6x + 27
