Answer:

Use a series dilution

Explanation:

The rationale behind the experiment is that the different substances absorb light at different wavelengths. To prepare an absorption spectrum for a purified solution of b-carotene dissolved in acetone, firstly, the \beta -carotene needs to be diluted enough to reach the light spec in the 20 tube. This will be done through a series of serial dilutions of a known concentration of the chlorophyll component. The bankmill will consist of acetone only and 1 blank will be needed. The range of the wavelength would be in the range of 400 - 700 nm. So, the intervals of 20 nm will suffice. Then, the OD for each wavelength will be used to determine the adsorption.

Answer:

Correct Answer: The least likely question to be included in the ethic test is:

A) What Health-Tech employees will be affected by my actions?

Explanation:

This is because, it does not have a direct implication to the code of conduct expected by the Health-Tech's company when compared with others. <em>For example, seeing a fraud going on in the company, it is expected that the staff should report to the appropriate management staff irrespective of whether the action would affect the staff's friend or not.</em>

malfutka [58]

Answer:

a) $94.88

b)  in 1 year, the intrinsic price of the stocks should increase to $109.11

Explanation:

year                      dividend              EPS

0                              0                       $10

1                               0                       $12

2                              0                       $14.40

3                              0                       $17.28

4                              0                       $20.736

5                              0                       $24.8832

6                              $11.45               $28.61568

growth rate up to year 5 = 20%

ROE growth rate starting year 6 = 15%

dividend growth rate starting year 6 = 15% x (1 - 40%) = 9%

cost of equity = 15%

horizon value at year 5 = $11.45 / (15% - 9%) = $190.83

current intrinsic value per stock = $190.83 / 1.15⁵ = $94.88

intrinsic price in 1 year = $190.83 / 1.15⁴ = $109.11
