Answer:
a. 5.18%;
b. 10.12%;
c. 6.32%;
d. 9.22%.
Explanation:
We apply the formula of Annual rate of return to calculate for the four cases.
The formula for calculating annual rate of return as below:
Annual rate of return = ![\sqrt[year]{Ending value/Beginning value}](https://tex.z-dn.net/?f=%5Csqrt%5Byear%5D%7BEnding%20value%2FBeginning%20value%7D)
-1 ;
So, for each of the case given, by applying the formula, the detailed calculations for each case will be:
+ For case a :
![\sqrt[12]{769.5/420} -1](https://tex.z-dn.net/?f=%5Csqrt%5B12%5D%7B769.5%2F420%7D%20-1)
= 5.18%;
+ For case b:
![\sqrt[14]{11,567.45/3,000} -1](https://tex.z-dn.net/?f=%5Csqrt%5B14%5D%7B11%2C567.45%2F3%2C000%7D%20-1)
= 10.12%;
+ For case c:
![\sqrt[20]{110,000/32,303.47} -1](https://tex.z-dn.net/?f=%5Csqrt%5B20%5D%7B110%2C000%2F32%2C303.47%7D%20-1)
= 6.32%;
+ For case d:
![\sqrt[40]{1,100,000/32,275.63} -1](https://tex.z-dn.net/?f=%5Csqrt%5B40%5D%7B1%2C100%2C000%2F32%2C275.63%7D%20-1)
= 9.22%.
Answer:
The correct answer is letter "D": incorrect because all inputs are varied in the example.
Explanation:
The law of Diminishing Marginal Productivity states that increasing one variable will keep the others the same. My initially increase output but eventually adding more of that one variable may lead to a diminishing rate of return. The law helps explain why increasing production is not always the best way to increase profits.
The law of Diminishing Marginal Productivity only applies when certain inputs are fixed, but in this example, the amount of labor available varies since it is increasing.
If the government and central bank don’t follow the economic policy, it could result in an economic depression
If aggregate demand in the long run is falling for several months in a row, it will make aggregate market results in an increase in the price level but no change in real production. The level of real production resulting from the aggregate demand shock is full-employment real production.
Aggregate demand can be described as a measurement of the total amount of demand for all finished services and goods produced in an economy. Aggregate demand is expressed as the total amount of money exchanged for those services and goods at a specific point in time and price level.
The model of aggregate demand and long-run aggregate supply predicts that the economy will eventually move toward its potential output. To see how nominal wage and price stickiness can cause real GDP to be either above or below potential in the short run, consider the response of the economy to a change in aggregate demand.
