Lock

Explanation:

Locks is a mechanism to avoid the access of records from interacting with one another either in the form of user objects for example tables and/or rows or system objects not cannot be seen by the user such as data shared in memory.

The system (Oracle) obtains all the required locks when executing the transaction request so as to avoid any hassle faced by the user and so that they don't require to be bothered by it. This way the system provides both highest degree of data monitoring with lowest restriction.

Moreover, a fail safe data integrity is provided by the system in case of any failure. This lock can also be done manually by the user.

You are given an investment to analyze. the cash flows from this investment are end of year 1. $19,340 2. $2,280 3. $26,600 4. $

AleksandrR [38]

PW = FW×(1+i)^-n

PW = $19340×1.15^-1 + $2280×1.15^-2 + $26600×1.15^-3 + $24240×1.15^-4 + $8770×1.15^-5 = $54250.90

hence PW = $54250.90

What is the range for the relative price of cloth such that the economy produces both cloth and food? From _______ to _______ .

dezoksy [38]

The answer is explained in detail below

Explanation:

$a_{KC} = 2$

$a_{LC} = 2$

$a_{KF} = 3$

$a_{LF} = 1$

Labor, L = 2000; Capital, K = 3000

Labour constraint,

$2Q_{c} + Q_{F} \leq 2000$

Capital constraint ,

$2Q_{c} + 3Q_{F} \leq 3000$

Solving the equation further, we get

$Q_{F} \leq 2000 - 2Q_{C}$

$Q_{F} \leq 1000 - \frac{2}{3} Q_{C}$

The range for the relative price of cloth such that the economy produces both cloth and food is 2/3 and 2

Low cloth production → economy will use relatively more labor to produce cloth → opportunity cost of cloth is 2/3rd units of food.
High cloth production → economy dips on labor → taking capital away from food production → raising opportunity cost of cloth to 2 units of food.

If relative price of cloth lies between 2/3 and 2 units of food, the economy produces both goods.
If the price of cloth decreases below 2/3 → complete specialization in food production → low compensation for producing cloth
If the price of cloth rises above 2 → complete specialization in cloth production → low compensation for producing food

On January 1, 2021, Blake Corporation issued 1,000 of its 9%, $1,000 callable bonds for $1,060,000. The bonds are dated January

Paul [167]

Answer:

$1,076,000

Explanation:

The computation of the carrying value of the bonds is shown below:

= Face value of the bond + unamortized bond premium

= $1,060,000 + $16,000

= $1,076,000

We simply added the face value of the bond and the unamortized bond premium so that the carrying value of the bond could come
