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:
C. Business writing uses less complex sentences, plain language, and a personable tone.
Explanation:
Characteristics of Good Business Writing. Accurate, so it leaves no room for error or misunderstanding. Clearly written, so that it is easy to understand the message and obvious what action the reader needs to take if any. Logical in structure, so the thought process of reasoning is easy to follow.
Answer:
late in the message, after most of the advantages of a product have been discussed.
Explanation:
The stardard procedure for introducing a higher price especially for new products is to include it after sharing the advantages of the new product.
It is essential because the core message that people or intending buyers want to hear are the benefits of the new product and how it can work better than what they have been using before.
The pricing should come at a later stage after which most of the information have been shared and not at the begining otherwise , it will scare intending buyers away due to its high price coupled with the fact that there exist similar product for other brand with lower prices in the market.
Answer: The actual value
Explanation: In simple words, actual value refers to the utility satisfaction that a customer receives after purchasing a product.
The only difference between perceived value and actual value is that while calculating perceived value the customer compares his product with other product . However, while calculating actual value he only compares the existing performance with his or her expectations.
In the given case, Jeremy feels the product he buy is no as useful as he thought. Hence it lacks actual value.
