The graph shows the distance of a car from a measuring position located on the edge of a straight road. What was the average velocity of the car from t = 0 to t= 30 seconds? 300- distance (feet) 200- 100- 10 20 time (seconds) 30 The graph shows the distance of a car from a measuring position located on the edge of a straight road. What was the average velocity of the car from t = 10 to t = 30 seconds? 300- distance (feet) 200 100- 10 20 time (seconds) 30 The graph shows the distance of a car from a measuring position located on the edge of a straight road. How fast is the car traveling at t = 18 seconds? 300- distance (feet) 200- 100- 10 20 time (seconds) 30 Find the slope of the line in the graph below which is tangent to f(x) = x at the point (1, 1). 10 -10 -5 LO 5 0 -5- -10 5 1.0
