Consider a swimming pool that initially contains 200 gallons of water. water is added to the pool using a 40 gallon bucket, one full bucket every minute.
(a) write an equation for the difference w(n+1)âw(n), which models this situation, where w(n) is the amount of water gallons as function of the number of minutes.
(b) write the initial condition for the differentce equation above. w(0)=

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 (%).
