Suppose that a cost-minimizing firm uses two inputs that are perfect substitutes.If the two in-puts are priced the same，what do the conditional factor demands look like for the inputs？

21. Nan Chen, CFA, is comparing a firm with two of its industry competitors. She obtains the following financial excerpts from the firm’s financial statements, as well as the inventory turnover ratio on two of its competitors.

The firm uses the LIFO inventory costing method under U.S.GAAP, which is consistent with its industry competitors. What conclusions should the analyst reach when comparing the firm’s inventory turnover ratio to those of ties competitors？ A. Outperformed both competitors. B. Outperformed Company 1 only. C. Outperformed Company 2 only.

nction is depicted by the formula C = 5X + 6Y, where C = contribution, X = the number of product X to be produced and Y = the number of product Y to be produced. Each unit of X uses 2 kg of material Z and each unit of Y uses 3 kg of material Z. The standard cost of material Z is $2 per kg. The shadow price for material Z has been worked out and found to be $2·80 per kg. If an extra 20 kg of material Z becomes available at $2 per kg, what will the maximum increase in contribution be？

A.Increase of $96

B.Increase of $56

C.Increase of $16

D.No change

You are the network administrator for the Beijing office of TestKing. A branch

office is located in Cairo. The DNS servers in both locations run Windows Server

2003.

The network uses two DNS namespaces internally. They are named

publishing.testking.com and testking.com. The locations of the primary name

servers are shown in the following table.

The Beijing office contains some servers that are registered in the testking.com zone

and other that are registered in the publishing.testking.com zone. All computers in

the Beijing office are configured to use the local DNS server as their preferred DNS

server. The two offices are connected only by using a VPN through the Internet.

Various network problems occasionally result in loss of connectivity between the

two offices.

Firewalls prevent the DNS servers in both offices from receiving queries from the

Internet.

You need to configure the DNS server in the Beijing office to allow successful

resolution of all queries from the Beijing office for names in the

publishing.testking.com namespace, even when the VPN link between the Beijing

and Cairo offices fails.

What should you configure on the DNS server in the Beijing office？（）

"High tech" and "state of the art" are two expressions that describe the modem technology. High tech is just a shorter way of saying high technology. And high technology describes any invention, system of device that uses the newest ideas or discoveries of science and engineering. What is high tech？ A computer is high tech. So is a communications satellite. A modem manufacturing (生产) system is surely high tech. High tech became a popular expression in the United States during the early 1955’s. Because of improvements in technology, people could buy many new kinds of products in American stores, such as home computers, microwave ovens, etc.

"State of the art" is something that is as modem as possible. It is a product that is based on the very latest methods and technology. Something that is "state of the art" is the newest possible design or product of a business or industry. A state of the art television set, for example, uses the most modem electronic design and parts. It is the best that one can buy.

"State of the art" is not a new expression. Engineers have used it for years, to describe the best and most modem way of doing something. Millions of Americans began to use the expression in the late 1970’s. The reason was the computer revolution. Every computer company claimed that its computers were "state of the art".

Computer technology changed so fast that a state of the art computer today might be old tomorrow. The expression "state of the art" became as common and popular as computers themselves. Now all kinds of products are said to be "state of the art".

What is the purpose of the passage？________ 查看材料

A.To tell how "high tech" and "state of the art" have developed.

B.To give examples of "high tech".

C.To tell what "high tech" and "state of the art " are.
