Write a program to help a small company calculate the amount of money to pay its employees. In this simplistic world, the company has exactly three employees. However, the number of hours per employee may vary. The company will apply the same tax rate to every employee

• The program must be written in Java.
• Prompt the user for the inputs and store the values in variables
• Must include all the inputs and outputs listed here and perform the calculations correctly
  • Inputs (entered by the user of the program)
    • Name of the first employee
      • Hourly rate
      • Number of hours worked
    • Name of the second employee
      • Hourly rate
      • Number of hours worked
    • Name of the third employee
      • Hourly rate
      • Number of hours worked
    • Tax rate (between 0 and 1.0)
  • Processing and Output
    • Calculate and display the amount each employee will be paid before taxes
    • Calculate and display the amount each employee will be taxed
    • Calculate and display the amount each employee will be paid after taxes have been withheld
    • Calculate and display the total amount of taxes the company will withhold
• Make the output look attractive
• Comment your code.

You may separate the processing/calculation step from the output step or you may combine those steps. It is your choice

Kinetic Properties of a Key Enzyme of Prostaglandin Synthesis

Prostaglandins are derived from the 20-carbon fatty acid arachidonic acid in a reaction catalyzed by the enzyme prostaglandin endoperoxide synthase. The enzyme converts arachidonic acid to PGG₂, the immediate precursor for many prostaglandins. The table below show the result of enzyme activity with or without an inhibitor, ibuprofen.

You need first to determine the V_max and K_m, with and without the inhibitor, and then determine which type of inhibitor Ibuprofen is.   The data given here makes it does not afford convenient assessment of V_max and K_m by conventional Michaelis Menten graph (since saturation is not reached under the experimental conditions). Therefore, a Lineweaver-Burke analysis is required. Fill the table with the reciprocal values. The results then are to be drawn as a non-logarithmic graph (next page).

Please show the equation on how to find the 1/[s], the 1/Vo and the 1/Vo[Ib] in the chart. Thank you

1. Frane Ltd has available two investment opportunities with the following risk return
characteristics

Frane Ltd plans to invest 65% of its available funds in Security A, and 35% in B.
The directors believe that the correlation coefficient between the returns of the
securities is +0.2.

(i) Calculate the expected return of the portfolio and the risk of the portfolio.

E(RP)=15.45%

σp= 4.18%

This one I have calculated, thank you.

(ii) Suppose the correlation coefficient between A and B was -1.0. How should Frane
Ltd invest its funds in order to obtain a zero risk portfolio?

by using ( a – b )² = a²-2ab+b²

I have tried, but also don't know how to do. Thank you.

σp² = (xσA)² + [(1-x) σB]² + 2x(1-x) ρAB σAσB

= (0.65 x 0.04)² + (0.35 x 0.08)² + 2(0.65)(0.35)(-0.1)(0.04)(0.08)?

(iii) According to CAPM, “The only risk that matters to an investor is
non-diversifiable risk.” Do you agree with the comment?

2. “Both trade-off theory and pecking order theory explain why companies may differ
in their levels of gearing.” Discuss this statement.

Suppose you and most other investors expect the inflation rate to be 7% next year, to fall to 5% during the following year, and then to remain at a rate of 3% thereafter. Assume that the real risk-free rate, r , will remain at 2% and that maturity risk premiums on Treasury securities rise from zero on very short-term securities (those that mature in a few days) to a level of 0.2 percentage points for 1-year securities. Furthermore, maturity risk premiums increase 0.2 percentage points for each year to maturity, up to a limit of 1.0 percentage point on 5-year or longer-term T-notes and T-bonds.

a. Calculate the interest rate on 1-, 2-, 3-, 4-, 5-, 10-, and 20-year Treasury securities, and plot the yield curve.

b. Now suppose ExxonMobil’s bonds, rated AAA, have the same maturities as the Treasury bonds. As an approximation, plot an ExxonMobil yield curve on the same graph with the Treasury bond yield curve. (Hint: Think about the default risk premium on ExxonMobil’s long-term versus short-term bonds.)

c. Now plot the approximate yield curve of Long Island Lighting Company, a risky nuclear utility.

A patient is admitted to the ICU with severe necrotizing pancreatitis. A few hours after admission, he developed increasing oxygen requirements and was intubated for hypoxemic respiratory failure. Initially, his oxygen saturation improved to the mid-90% range on an FiO₂ of 0.5 (50%), but in the past 2 hours, the nurse has had to increase the FiO₂ back to 0.7 (70%) and his SaO₂ is still in the lower 90% range. The patient remains on a PEEP of 5 cmH₂O. The respiratory therapist drew an ABG which shows pH 7.35, PCO₂ 38, PO₂ 60, HCO₃ - 22 on an FiO₂ of 0.8 (80%). The patient's repeat chest x-ray is shown a "ground glass appearance". An echocardiogram performed earlier in the day revealed normal left ventricular function.

How do you explain his worsening oxygenation status?

What can you do to improve his oxygenation?

What other changes should you consider making in the ventilator settings?

If his oxygen saturation fails to improve despite being on high levels of support (i.e., FiO₂ of 1.0 and 20 cm H₂O of PEEP), what other options do you have for improving his oxygenation?
