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 store rent that should be allocated in department 3 is $100000
Explanation:
if we assume that we charge the rent per square feet occupied, then we can say
department rent = charge per square feet* number of square feets
r = k*sf
also if
total rent = rent department 1 + rent department 2 + rent department 3
r total = r1 + r2 + r3 = k*sf1 + k*sf2 + k*sf3 = k*( sf1 + sf2 + sf3)
k= r total / ( sf1 + sf2 + sf3)
replacing values
k = $200000/(15000 sq.ft + 10000 sq.ft +25000 sq.ft ) = $ 4 per sq.ft
thus for department 3
r3 = k* sf3= $ 4 per sq.ft * 25000 sq.ft = $100000
rent department 3 = $100000
Answer:
The option (b) 2.4 is correct.
Explanation:
We can find price elasticity of demand by using the formula shown in the attachment attached with.
Since we know the quantities of product associated with the market price of the product, by putting values in the equation we have:
Price elasticity of Demand =
= [(6000 - 4000) / (6000 + 4000)/2] / [(13 - 11) / (13+11)/2]
Price elasticity of Demand = 2.4
So this is how we can find the price elasticity of supply which says that the producers will respond to prices drop by producing lower quantity of product.
Answer:
True
Explanation:
Intel is a major computer hardware supplier in the world, and its friend Microsoft buys hardware parts from them which it uses in manufacturing computers such as processor chips.
In respect to the bargaining power of suppliers in Porter's five forces model of industry competition, Intel acts as a supplier to Microsoft. And because of Intel's bargaining power like its market dominance and limited competitors, it can set prices which the–Microsoft has no choice but to purchase.
Answer: It is better to delete the check than void the check in order to erase all records of the transaction
Explanation:
When a check is deleted, it should be noted that such check is being removed entirely from the system and also the transaction of the check will no longer be visible anywhere in the system.
Voiding a check mean that the amount of the transaction on the check will be changed to zero but it should be ited that a record of such transaction will still be kept in QuickBooks but deleting it will help remove the transaction in QuickBooks.
When a check is voided, the check details like the check number, account, payee, memo and date will be unchanged, even though the amount will change to zero.
Therefore, the option that says that it is better to delete the check than void the check in order to erase all records of the transaction isn't true.
