The following table shows the amount of water leaking from an inflatable pool as a function of time:
time (in minutes)
x water (in liters)
f(x)
0 35
1 30
2 25
3 20
4 15
find and interpret the meaning of the x‐intercept in this scenario.
(7, 0); the time it takes to empty the water in the pool
(5, 0); the time it takes to empty the water in the pool
(5, 0); the time it takes to fill up the water in the pool
(7, 0); the time it takes to fill up the water in the pool

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 (%).
