Answer:
Suppose the cost per hour incurred in operating a cruise ship is 3a + b 
dollars per hour, where a and b are positive constants and v is the ship's speed in miles per hour. At what speed (in miles per hour) should the ship be operated between two ports, at a distance D miles apart, to minimize the cost? (Hint: Minimize the cost, not the cost per hour.)
<em>The speed at which the ship would maximize cost is </em>![\sqrt[3]{\frac{3a}{2b} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B3a%7D%7B2b%7D%20%7D)
Explanation:
The problem can be solved using differentiation to get the minimum value of the speed to travel between the two ports. Step by step calculation is contained in the attached images;

Answer:
The specified preferences of Charles, Diana and Juanita. Charles and Juniata prefer chocolate over red velvet cake. Dina favors red velvet over chocolate.
So, when there is voting among red velvet and chocolate cake, the majority will select the Chocolate cake and among winner and vanilla majority will vote for Vanilla cake.
This is because Dina and Juanita favor vanilla over chocolate.
Among Chocolate and vanilla cake, the majority will elect for vanilla and among this winner and red velvet cake, the majority will choose for Red velvet cake.
This is because Diana and juanita favor vanilla over chocolate. So, vanilla cakes get majority elects. When there is voting among vanilla and red velvet , red vanilla acquire majority votes as charles and dina favor red velvet over vanilla.
The statement is False. The preferences are not transitive.
In the first situation chocolate is chosen to vanilla and red velvet is preferred to vanilla. Although, in the second situation, chocolate is favored to red velvet and vanilla is preferred to chocolate. Thus, the preferences do not exhibit transitivity.
Answer:
B. The portfolio expected rate of return must be the same for each economic state.
Explanation:
Variance formula = sum of (probability x (r - mean)^2)
r= expected return
if the expected return would be same for each economic state then the mean would equal to expected return which ultimately will give variance zero ( as r-mean would be 0).
Hence the correct option is B. The portfolio expected rate of return must be the same for each economic state.
Answer: This loan would would have priority over the other unsecured claims in this bankruptcy case.
Explanation:
Since the trucks are secured collateral the loan is a secure loan. It will be the priority in the bankruptcy case since the other claims were unsecured. The law firm would have a right to the trucks since he owed them 20,000$ and put them up as collateral.
Everything that was an unsecured loan does not have anything to take from and will be a loss for the other companies who filed against Henry Anderson.
