Answer:
C. The electric car is not moving at 0 seconds and 12 seconds.
Step-by-step explanation:
Given:
The table given is:
x 0 2 4 6 8 10 12
y 0 45 72 81 72 45 0
From the above table, we observe that the car starts from rest and its speed increases from 0 to 6 seconds, the maximum speed being 81 mph.
After 6 seconds, the speed of the car goes on decreasing till it stops at time equal to 12 seconds.
So, the speed of the car at the start when is 0 mph as it is at rest at that time.
Also, when the time is , the car has come to a stop and thus its speed has reduced to 0 mph again. So, the car is not moving after 12 seconds.
From the above conclusion, we can say that only option C is correct.
The electric car is not moving at 0 seconds and 12 seconds.
Answer:
Step-by-step explanation:
Let, the length of the rectangle be 'L'
and, width of the rectangle be 'W'
length=2*Width+3
Area of the rectangle= 90 square feet
Area of a rectangle = Length*Width
Using Factorization Method to solve quadratic equation:
Taking common from the equation:
OR
The Width cannot be negative, therefore Width(W)=12 feet
