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;
The one that distinguishes money from the other assets is that it is used as a medium of exchange
Explanation:
Money is one of the most important factor in our day to day lives it has become as defining the country's economic standard and it is widely accepted all over the world
Money is used as the medium of exchange because we can buy all the necessary things using the money and can use it as a medium to exchange of goods and services. There are also other important functions as the method of comparing the values
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.
