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:
A. Create three Record Types (Widget A, Widget B, Widget C) with six Page Layouts (Sales Widget A, Sales Widget B, Sales Widget C, Marketing Widget A, Marketing Widget B, and Marketing Widget C).
Explanation:
This question is about Salesforce, and the reason I chose A is because:
- Option B is not correct because ti would be too messy to use only one Record type.
- Option C is not correct because you need a 6 page layout and that option includes only a 1 page layout.
- Option D is unnecessarily complicated since you can use only 3 record types and using 6 would not help you at anything.
Answer:
<u>Monopolist competition</u>.
Explanation:
The market structure of monopolistic competition occurs when there are several companies offering similar products, which even though substitute products cannot be considered perfect substitutes. Monopolistic competition is characterized when in the market there are many sellers competing for a higher market position of some product or sector. This type of monopolistic competition is characterized by free entry to other companies, which makes it increasingly competitive in the pursuit of customer preference.
