If the rectangular field has notional sides X and y then it has area
A(x) =xy { =6•10^6 sq ft }
The length of fencing required, if
x
is the letter that was arbitrarily assigned to the side to which the dividing fence runs parallel, is:l (x) = 3x +2y
It matters not that the farmer wishes to divide the area into 2 exact smaller areas.
Assuming the cost of the fencing is proportional to the length of fencing required, then
C(x)=a L (x)
To optimise cost, using the Lagrange Multiplier
λ
, with the area constraint :
So the farmer minimises the cost by fencing-off in the ratio 2:3, either-way
Answer:
The diver's new depth is <u>14.4 feet</u>.
Step-by-step explanation:
Given:
A scuba diver is swimming 18 feet below the water's surface.
The diver swims up slowly at 0.6 feet per second for 5 seconds and then swims up for 2 more seconds at 0.3 feet per second.
Now, to find the diver's new depth.
As given,
Total depth = 18 feet.
Total distance covered:
Now, to get the new depth:
New depth = Total depth - distance covered.
Therefore, the diver's new depth is 14.4 feet.
