Consider the following five constraints x1 + 2x2 ≤ 3, x1 − x2 ≥ 0, 2x1 + x2 ≤ 3, x1 + 5x2 ≤ 6, x1 − 2x2 ≥ −1. (a) Sketch the fea

sible region and find the degenerate vertex x0. (b) How many possible working sets are there at x0? (c) Suppose that we wish to minimize x1 + x2 subject to these constraints, starting at x0 and using the simplex method. Find a working set A0 for which the Lagrange multiplier vector λ (the solution of AT 0 λ = c) contains at least one negative component λs, but the simplex search direction satisfying A0p = es is not a feasible descent direction. Draw a picture showing p emanating from x0. What are the blocking constraints? (d) Under the same conditions as in part (c), find a working set A¯ 0 for which the Lagrange multiplier vector contains at least one negative component, but the associated search direction ¯p is a feasible descent direction. Draw a picture showing ¯p emanating from x0. (e) Can you find a feasible descent direction at x0 if we wish instead to minimize −x1 − x2? Explain your answer.

Zino Company determines that a customer balance of $200,from Hollis Co. is uncollectible. Zino uses the allowance method to acco
Natalka [10]

Answer:

The correct answer is A

Explanation:

The journal entry to be posted to write off the balance of uncollectible is as:

Allowance for Doubtful Accounts A/c..........................Dr   $200

              Accounts Receivable A/c.......................................Cr  $200

As the allowance method is used so the accounts receivable account will be credited and the allowance for doubtful accounts is debited with the amount which is recovered that is $200.

Allowance method is generally refer to one of the ways for reporting the uncollectible or bad debt expense which results from a company selling the goods on credit.

fredd [130]

Answer:

D. focus on adding unique features to her product that customers will value.

Explanation:

Differentiation strategy is the strategy that aims to distinguish a product or service, from other similar products, offered by the competitors in the market. It focuses on the development of a product or service, that is unique for the customers, in terms of product design, features, brand image, quality, or customer service.  

The focus of competition in a differentiation strategy tends to be on unique product features, service, and new product launches, or on marketing and promotion rather than price. A differentiator would focus research and development on product features or packaging in order to add uniqueness.

Hence, Nendry should focus on adding unique features to her product that customers will value.

A manufacturer reports the following information below for its first three years in operation.
Usimov [2.4K]

Answer:

e. $111,000

Explanation:

Absorption costing income for year 3 = Income under variable costing - {Beginning inventory (units) * Fixed manufacturing overhead per unit} + {Ending inventory (units) * Fixed manufacturing overhead per unit}

Absorption costing income for year 3  = 115,000 - (500*8) + (0*8)

= 115,000 - 4,000 + 0

= $111,000

In-s [12.5K]

Answer:

B

Explanation:

We are to find the present value of the annuity

Present value is the sum of discounted cash flows

Present value can be calculated using a financial calculator

Cash flow each year from year 1 to 10 = $4,800

I = 5%

Present value = 37,064.16

To find the PV using a financial calculator:

1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.

2. after inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.  

3. Press compute
