Consider the graph shown in the figure, which gives the velocity of an object moving along a line. Assume time is measured in hours and distance is measured in miles. The areas of three regions bounded by the velocity curve and the t-axis are also given. Complete parts (a) through (e). a. On what intervals is the object moving in the positive direction? Select the correct choice and, if necessary, fill in the answer box to complete your choice. A. The object is moving in the positive direction on the interval(s) [0,2),(6,10). (Type your answer in interval notation. Use a comma to separate answers as needed.) OB. The object is never moving in the positive direction. b. What is the displacement of the object over the interval [0,6]? Using the values shown in the graph, the displacement of the object over the interval [0,6] is miles. 11 10 + 2 4 8 10 15
