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:
price of wheat to increase, the supply of bread to decrease, and the demand for potatoes to increase.
Explanation:
A drought will reduce the supply of wheat thereby causing the supply curve to shift upwards (to the left) leading to an increase in the price of wheat. Since wheat is a basic ingredient in producing bread, an increase in the price of wheat will increase the cost of producing bread. An increase in cost of producing bread will reduce the supply of bread, shifting the supply curve to the right.
Potatoes and bread are close substitutes and therefore, have a competitive demand. An increase in the price of bread will increase the demand for potatoes because rational consumers will opt for a cheaper alternative considering their money income.
Answer:
the amount charged on a job is $401.50
Explanation:
The computation of the amount charged on the job is shown below:
The Amount to be charged is
= Material Loading Charge + Labor Charge + Materials Cost
= 35% × $110 + $23 Per Hour × 11 Hours + $110
= $38.50 + $253 + $110
= $401.50
Hence, the amount charged on a job is $401.50
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:
The __Paasche Index or Current-Weighted Index_______ is based on all the goods and services produced in the economy, which make it a current-weights index.
Explanation:
The Current-Weighted Index is an index that calculates the weighted average of prices or quantities or with the weights used proportionate to the quantities or prices of the goods. At regular intervals, the weights have to re-calculated in line with the current realities. This regular re-calculation of the weights, which is the basis for its name, makes it current.
