The table below represents the velocity of a car as a function of time: time (seconds) x velocity (m/s) f (x) 15 45 22 66 29 87 36 108 the average rate of change of the function between x = 15 to x = 29 is 87 m/s2 and represents the car's acceleration.

Acompany manufactures large valves, packed in boxes. a shipment consists of 1500 valves packed in 75 boxes. each box has the outer dimensions 1.2 x 0.8 x 1.6 m and the inner dimensions 1.19 x 0.79 x 1.59 m. the boxes are loaded on a vehicle (truck + trailer). the available capacity in the vehicle combination is 140 m3. each valve has a volume of 0.06 m3. - calculate the load factor on the box level (%). - calculate the load factor on the vehicle level (%). - calculate the overall load factor (%).
