Answer:
what grade is this?
Step-by-step explanation:
That would depend on how many vehicles there are. The question is not complete.
Answer:
Step-by-step explanation:
We are given an expression to solve for the displacement (x), so in order to find velocity (v), we need to differentiate the function.
============================================================
Solving :
⇒ 
⇒ 
⇒ 
⇒
Using this equation, we can find the velocity if a value of t is given.
Answer:
The answer is -8.
Step-by-step explanation:
The absolute value is the distance between a number and zero, and it is always positive. The distance between -8 and 0 is 8. Then, once the absolute value is found, the actual answer needs to be found by multiplying 8 by (-1). Usually the number in front of an absolute value is 1; however, this absolute value has a negative in front of it, which causes the 1 to become a -1. Thus, causing the final answer to be -8.
