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.
Explanation:
Secured bonds are bonds that have specific assets of the issuer pledged as collateral. In other words they are a type of bond that is bought by pledging a specific asset, which acts as a collateral on the loan that you are giving the company. Which if the issuer were to default on the payment then the issuer must transfer ownership of the asset to the holder of the secured bond.
Answer: B. Nina will prefer L to M.
Explanation:
Convex utility of wealth function, u(x) is the risk-loving consumer having a a convex utility function, it's slope gets steeper as the wealth increases making the curvature of the utility function measuring the customer's attitude towards risk
Nina will prefer L to M as she has convex utility function as risk loving.
Answer:
Break-even point in units= 93 units
Explanation:
Giving the following information:
Its fixed costs are $1000 a week and its variable costs for one batch of umbrellas per week are $500 for 2000 units.
After doing market research, the company sets the price per umbrella at $11.
Unitary variable cost= 500/2,000= $0.25
To calculate the break-even point in units, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 1,000/ (11 - 0.25)
Break-even point in units= 93 units
Answer:
Acceptable
Explanation:
The acceptable use policy is also known as fair use policy or the acceptable usage policy. It is a document or set of rules that is applied by the owner or by the management of nay organization or company that restricts and prevents the use of many equipment and other tools and machinery which could harm other coworker, other assets of the company or the legal standing of the company.
