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.
1. Factor out the greatest common factor (GCF). (There will not always be one).
2. Count the number of terms.
3. Check to be sure each factor is prime, if not, repeat 1-3.
4. Check by multiplying the factors out to see if you get the original polynomial.
Answer:
Mark!
Step-by-step explanation:

Chris ate 1/4 which would be 5, he would have 15 left
Answer:
the maximum height is 1054.500 meters
Step-by-step explanation:
h ( t ) = − 4.9t^2 + 133t + 152
a= -4.9 , b= 133 and c= 152
To find maximum height , we find vertex
Now plug in 13.5714 for 't' in h(t)
the maximum height = 1054.500 meters
