Answer: Choice A. It travels for 1 hour, stops for 1 hour, then travels for 3 hours
------------------------------------------------
Any portion of the graph that isn't flat and horizontal is when the car is traveling. In this case, it's the portion from x = 0 to x = 1 (the first hour of travel) and the portion from x = 2 to x = 5 (the final three hours of travel). The flat portion starts at x = 1 and stops at x = 2. So this represents 1 hour of rest. This is where the distance (y) isn't changing.
The answer would be 9v ^4 + 27v ^3 - 36v^2
Step-by-step explanation:
You first would multiply each term in the parenthesis by 9v^2
9v^2 (v^2) + 9v^2 (3v) - 9v^2 (4)
After this you combine the like terms
9v^2 * v^2 is 9v^4
9v^2 * 3v is 27v^3
-9v^2 * 4 is -36v^2
Because you can not simplify it any smaller, this is your final answer
Answer:
