Complete Question
Water is flowing in a trapezoidal channel at a rate of Q=20m³/s . The critical depth y for such a channel must satisfy the equation:
0 = 1 − Q² / gA³c . B Where g= 9.81m /s² and Ac = the cross-section area can be related to depth y by B = 3+y and Ac = 3y+y²/2. Solve for the critical depth using (a). the graphical method,
Answer:
Given the equation,
0 = 1 − Q² / gA³c. B
Now substituting the given value g= 9.81m /s² , Q =20m³/s, B = 3+y, and Ac = 3y+y²/2,
We get:
0 = 1 - 20² / (9.81) ( 3y + y²/2)³ (3+y)
Hence we choose f(y) = 1 - 40.7747 / (3y + y²/2)³ . (3 + y) and solve for f(y) = 0
Therefore,
To solve using a graph, we take twelve sample points ( starting at y = 0.25 in step of 0.25m and plot a graph using MS- Excel. Kindly find the graph below.
2) As evident from the sample point and the graph function f(y) gets close to zero at y = 1.5, hence the root of f(y) = 0 is Xr = 1.5
Answer:
The correct answer is: market prices that are determined by consumers and producers acting in their own self-interest.
Explanation:
In a market system, the price of a good is determined by the intersection of demand for goods by consumers and the supply of goods by the producers. The price is determined at the point where the market forces of demand and supply are equal.
The producer is trying to maximize its profit while the consumer is trying to maximize its utility. Both are working for their self-interest and in this way are able to allocate scarce resources through the working of the market system.

Answer:
B. Kenji has the lowest opportunity cost.
Explanation:
The opportunity cost is those resources that a person gives up when making a choice or making a decision. If Lucia stopped working for an hour, stop receiving $ 120
. Otherwise, If Kenji stops working four hours, to shear the llamas, he stops receiving $ 80. Then, his opportunity cost is the lowest.
At least 20% should go to ur savongs
