Answer:
Initial Velocity= 49 m/s
Time period= 5 secs
Explanation:
THIS IS THE COMPLETE QUESTION BELOW
A rocket shoots up 123 meters. What is it initial velocity?How long is it ascending
The initial velocity can be calculated using the expression below
u= √( 2gh)
Where g= Acceleration due to gravity= 98 m/s^2
h= height
Substitute the values we have
u = √(2*9.8*123)
u=√( 2410.8)
u = 49 m/s
the time period can be calculated as
(49/9.8)
= 5 sec
Hence time period is 5 secs
Answer:
d. beta did a better job of explaining the returns than standard deviation
Explanation:
Beta measures the systemic risk associated with the particular investment, it do not compute the total risk associated, which is more logical.
Standard deviation computes the total risk associated.
Some risk is natural, like the risk of floods, natural calamities, earthquake, etc:
That risk shall not counted as for comparison as that is associated universally. Further, the risk associated with particular factors like bankruptcy of a company, or some legal case issue of a company are precisely described by beta coefficient.
Thus, beta provides better details about explaining the returns.
Answer and Explanation:
The computation of the present values of both alternatives is shown below:
For alternative one, the lump sum amount is
= Yearly payment × PVIFA factor at 8% for 12 years
= $50,000 × 7.5361
= $376,805
And, in the alternative 2, the lumpsum amount i.e. present value is $452,000
So as we can see that the alternative 2 is better as the lumspsum amount is high as compared with the alternative 1
Answer:
Portfolio return = 11.08%
Explanation:
<em>The expected return on the portfolio is the weighted average return of all the different stocks making up the portfolio. The weight of the individual stock would be the relative amount invested in each stock as a proportion of the total fund invested.</em>
The expected return can be determined as follows
Weighted of stock A= 15,200/(15200+23400)=0.39
Weight of stock B = 23.400/((15200+23400)= 0.61
Expected return on portfolio = (0.39 ×8.90% ) + (0.61*12.50%)= 11.08 %
Gross pay is the amount of income before taxes and deductions. The amount by which the gross pay is reduced is $174.66.
<h3>What is gross pay?</h3>
The gross pay is the amount of salary or wages that is before the taxes or other deductions. The expense of tax and deductions are subtracted from the gross pay to calculate the net pay.
The gross pay of Marquis in the given question is $816. His gross pay will be reduced by the taxes to calculate the net pay.
The amount of reduction will be the sum of all the taxes levied such as federal tax, social security tax, and so on.
Therefore the amount by which the gross pay will be reduced is:
The state tax is calculated as a percentage of federal tax. The state tax is:
Therefore the total amount of reduction is:
Hence, the correct option is d.
