Please please please answer this question for me THANK YOU!!! 40 POINTS

Step-by-step explanation:

The vertical axis represents distance traveled, and the horizontal axis represents time.

At the beginning, time = t = 0 and distance = d = 0.

Between t = 0 and t = 20, the group moved in the positive direction by 40 units.  Then, between t = 20 and t = 60, they stayed where they were, at distance 40 units from the origin.  (Slope of graph is zero; this means the rate of travel is zero.)

Between t = 60 and t = 120, the group moves further away from the origin (actually, further away from Point C, reaching Point D, which is 150 units from the origin.  

Between t = 120 and t = 160, the group is at rest / does not move.

Between t = 160 and t = 200, the group moves back to the origin (distance = 0) at a steady rate.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second
