Answer: The average velocity of the object over the time interval [3,6] is 20.
Step-by-step explanation:
Since we have given that
s(3) = 156
s(6) = 216
We need to find the average velocity over the time interval [3,6].
So, average velocity becomes

Hence, the average velocity of the object over the time interval [3,6] is 20.
Answer:
3a - 21
Step-by-step explanation:
3 ( a - 7 )
= 3 ( a ) + 3 ( - 7 )
= 3a - 21
