Answer:
E. Suppose a firm's total assets turnover ratio falls from 10% to 9%, but at the same time its profit margin rises from 9% to 10% and its debt increases from 40% of total assets to 60%. Under these conditions, the ROE will increase.
D I believe because the others do not seem very voluntary
Answer:
a. radius = 0.0006m = 0.6mm and length =0.393m = 393mm
b. frequency =377.86Hz
Explanation:
Given:
mass of steel= 4g = 0.004kg
density of steel = 7890kg/m3
tensile stress of steel 7.0x10⁸
tension load =900N
from the density, we will calculate for the Volume of the steel string
density = mass/volume
volume = mass/density = 0.004/7890 = 5.07 x 10⁻⁷ m³
from the tensile stress will can get the maximum base Area of the string ,
tensile stress = load/area =
7x10⁸ = 900/A
A = 900/7x10⁸ = 1.29x10⁻⁶ m²
Area = πr²
area/pi = 4.105x10-7
radius = 0.0006m = 0.6mm
volume = Area x length
length = vol/area =(5.07 x 10⁻⁷ m³)/1.29x10⁻⁶ m² = 0.393m
b. the highest possible frequency is given by:
F = 
where T= tension, m=mass, L=length
F = 
= 297.04/0.786
frequency =377.86Hz
Answer:
allocate a portion of the customer's portfolio to "Dot Com" stocks that will not reduce the customer's retirement income below the amount needed for comfortable living
Explanation:
Given that the potential client is concerned that his purchasing power is decreasing and wishes to allocate an increased portion of his portfolio to aggressive growth stocks.
Hence, the best recommendation is to "allocate a portion of his portfolio to "Dot Com" stocks that will not reduce his retirement income below the amount needed for comfortable living"
Answer: Option D
Explanation: As per the job characteristics theory an employee who is performing a job which have a high variety of task to complete and require some special skills will feel more motivated and satisfied than others.
In the given case, Jon has a feeling that his job makes him to perform new task everyday, that's why, he never gets board with his job.
Hence from the above we can conclude that the correct option is D.
