Answer 1

Hello there! The correct answer is C. The electric car is not moving at 0 seconds and 12 seconds.

In the question description it says that y represents the car's speed in miles. Now looking back at the chart, wherever the x values are at when y = 0, the car isn't moving at this time, because if the car is going at 0 miles per hour, it is not moving. Looking at the chart, you can see the car is going 0 miles per hour when x = 0 and x = 12. This means that C is your answer.

I hope this helps and have a great day!

Answer 2

A statement that is true about this situation include the following: C. The electric car is not moving at 0 seconds and 12 seconds.

In Mathematics and Geometry, speed is the distance covered by a physical object per unit of time. This ultimately implies that, the speed of any a physical object can be calculated by using this formula;

Speed = distance/time

Generally speaking, a physical object is considered as being static (not moving or in motion) when its speed is equal to zero (0).

In this context, we can reasonably infer and logically deduce that this new electric car is not moving at 0 seconds and 12 seconds because the speeds (y-avlues) at this time interval are equal to zero (0).

Complete Question;

Marcel is performing the first test on his company's new electric car During the test, the electric car reaches a maximum speed of 81 mph.

The performance test results of the electric car can be modeled by the following table, where x represents time, in seconds at the start of the test, and y represents the speed, in miles per hour.

A. The electric car is not moving at 6 seconds and 12 seconds.

B. The electric car is not moving at 4 seconds and 8 seconds.

C. The electric car is not moving at 0 seconds and 12 seconds

D. The electric car is not moving at 0 seconds and 6 seconds
