Answer:
I dont really know what your asking :/
Step-by-step explanation:
To minimize the cost, we take the straight distance from the refinery to the other side of the river as 2 km. Also, the 7 km will be the distance that has to be traveled by the pipeline in land. The total cost, C, is therefore,
total cost = (2 km)($800,000/km) + (7 km)($400,000 /km)
total cost = $4,400,000
Thus, the total cost of the pipeline is approximately $4,400,000.00.
The differnce quotient is basically taking the derivitive (result will be f'(x)=5, but anyway)
here is the disffernce quotient

so
for your equation



h's cancel and you are left with 5
the differnce quotient is 5
<u>Answer</u> i think the first one goes down by .3 every time but i am not 100$
Step-by-step explanation:
zero days, 3 hours + 20 min + 1 hour + 48 min = 308 min which is about 5 hours.
