How long should a key be used before it is replaced? Search the Internet for information regarding cryptoperiods for hash, symmetric, and asymmetric algorithms. Find at least three sources for each of the algorithms. Write a summary of what you find in regards to the recommended times and figure the average time between all three of your sources. Do you agree with the average time for a hash, symmetric, and asymmetric algorithms? What would you recommend for each? Why? Please make sure it is 150 words.

You are the manager of a healthcare facility that is considering different payment options for buying supplies for your facility. The annual charges for these supplies is $10,000 and the vendor is offering you three payment options to consider.

option 1: 3% discount if you make the full payment in 30 days.

option 2: quarterly payments at the beginning of each quarter with a service charge of $100 per quarter.

option 3: monthly payments at the beginning of each month with a service charge of 3% for each monthly payment.

Q1: Which of these three options provides the best value for money? Why?

Q2: Payments for these supplies are made from your bank account which has a current balance of $30,000 and earns monthly interest of 0.2%.

a. Which of these three options now provides the best value for money?

b. At what interest rate would you be indifferent between Options 1 and 2?

c. At what interest rate would you be indifferent between Options 2 and 3?

d. Consider the ending balances under each of these three options for interest rate ranging from 0.0% to 2.0%. Develop data tables to compute the ending balances for this range of interest (consider interest increments of 0.2%). Depict your results in a line graph.

Investment (more tools) and technological improvement (better tools) each contribute to economic growth by making labor more productive. What percentage of the U.S. economy is allocated to investment in a normal year? Also, describe how fast the U.S. economy grows in real terms on a per capita basis in an average year? (10 points)8. Present an analysis that shows how an increase in labor productivity (perhaps from more investment or perhaps from improved technology) will tend to impact the economy. Identify which of your results fit what we actually observe for the U.S. economy over time. Complete your answer to this question by identifying one economic policy you think will help enhance labor productivity. (15 points)9. Identify a change in fiscal policy that will shift the composition of output toward investment. Present a composition of output analysis to explain why the policy you suggest will tend to shift the composition of output toward investment

The net present value (NPV) method estimates how much a potential project will contribute to (-Select-business ethics, shareholders' wealth ,employee benefits), and it is the best selection criterion. The( -Select-smaller larger) the NPV, the more value the project adds; and added value means a (-Select-higher,lower) stock price. In equation form, the NPV is defined as:

CF_t is the expected cash flow at Time t, r is the project's risk-adjusted cost of capital, and N is its life, and cash outflows are treated as negative cash flows. The NPV calculation assumes that cash inflows can be reinvested at the project's risk-adjusted (-Select-rd, rs, WACC). When the firm is considering independent projects, if the project's NPV exceeds zero the firm should (-Select-accept, reject) the project. When the firm is considering mutually exclusive projects, the firm should accept the project with the (-Select-lowest positive, lowest negative, highest positive ,highest negative) NPV.

Quantitative Problem: Bellinger Industries is considering two projects for inclusion in its capital budget, and you have been asked to do the analysis. Both projects' after-tax cash flows are shown on the time line below. Depreciation, salvage values, net operating working capital requirements, and tax effects are all included in these cash flows. Both projects have 4-year lives, and they have risk characteristics similar to the firm's average project. Bellinger's WACC is 7%.

What is Project A's NPV? Do not round intermediate calculations. Round your answer to the nearest cent.

$  

What is Project B's NPV? Do not round intermediate calculations. Round your answer to the nearest cent.

$  

If the projects were independent, which project(s) would be accepted?

If the projects were mutually exclusive, which project(s) would be accepted?
