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;
Because he divided the population into smaller groups and then randomly sampled each group, he would be using a stratified random sampling procedure.
Answer: D. increases in government purchases.
Explanation:
Crowding out may occur simply due to expansionary fiscal policy that is, a situation wherby the government wants to increase the money in circulation and also increase its expenditure. This can lead to the government borrowing funds.
Crowding out may occur when fiscal policy involves increases in government purchases. This borrowing in turn, affects the money that will be available to the private investors as there'll be lesser funds for them.
Answer:
Instructions are listed below
Explanation:
Giving the following information:
The dinner-dance committee has assembled the following expected costs for the event:
Dinner (per person) $ 18
Favors and program (per person) $ 2
Band $ 2,800
Rental of ballroom $ 900
Professional entertainment during intermission $ 1,000
Tickets and advertising $ 1,300
The committee members would like to charge $35 per person.
1) Break-even point= fixed costs/ contribution margin
Break-evenn point= (Band+rental+professional entertainment+tickets)/[price - (dinner+favors)]
Break-even point= 6000/(35-20)= 400 individuals
2) Q= 300 P=?
300=6000/(P-20)
300*(P-20)= 6000
300P=12000
P=$40
Answer: positive
Explanation:
Based on the happening in he question, the method used is the positive discipline approach
This approach seeks ways to help an employee when the employee isn't being productive at his or her workplace. The positive actions are being seeked and necessary ways to bring the worker back to his or her feet will be utilized.
This is the method used in order to being Jennifer back on track and.make her productive again.
