Answer:

Following are the solution to the given question:

Explanation:

The decrease of a marginal input return implies that its input is increasing by one unit, thereby decreasing its marginal input product.

Function of production

F(K, L) = AK^{\frac{3}{4}} L^{\frac{3}{4}}

Its capital products subject (MPK) is derived by differentiating the factor of production from K.

MPK = \frac{3}{4}\times AK^{\frac{3}{4}} - 1L^{\frac{3}{4}}\\\\MPK = \frac{3}{4}AK^{-\frac{1}{4}}L^{\frac{3}{4}}\\\\MPK = \frac{3}{4}\times A\times (\frac{L^{\frac{3}{4}}}{K^{\frac{1}{4}}})

Note: When a value is changed from numerator to denominator, then the power symbol shifts between positive to negative.

Since k is in the denominator, K decreases \frac{3}{4}\times A\times (\frac{L^{\frac{3}{4}}}{K^{\frac{1}{4}}}), and therefore MPK is reduced.

There's hence a decreased effective return on capital again for production function.

Its marginal labor product (MPL) is determined by distinguishing the manufacturing function from L.

MPL = (\frac{3}{4})\times AK^{\frac{3}{4}}L^{\frac{3}{4}}-1\\\\MPL = (\frac{3}{4})AK^{\frac{3}{4}}L^{-\frac{1}{4}}\\\\MPL = (\frac{3}{4})\times A\times (\frac{K^{\frac{3}{4}}}{L^{\frac{3}{4}}})

The denominator of L reduces L (\frac{3}{4})\times A\times (\frac{K^{\frac{3}{4}}}{L^{\frac{3}{4}}}) and therefore reduces MPL.

So there is a decreasing marginal return to labor in the production function.

KATRIN_1 [288]

Answer: the difference between the present value of cash inflows and present value of cash outflows

Explanation:

The value of money is always changing and usually for the worst. Inflation means that $1 today is not worth $1 in a year's time. This poses a risk to investors who want to make profit and can't do that if they do not cater for inflation or the loss of value in their profit estimations. This is where Net Present Value comes in.

NET PRESENT VALUE works by subtracting the present value of Cash Outflows ( investment) from the present value of Cash Inflows (Revenue).

To do this, a DISCOUNT RATE is used which is essentially a value that people believe the currency involved will reduce by going forward. This Discount Rate equates the value of money in the future to it's value now.

Once that is ascertained, a proper comparison can be made to see if the investment is worth it.

A home buyer can afford to spend no more than $1500/month on mortgage payments. Suppose that the interest rate is 6%, that inter
krok68 [10]

Answer:

20 years mortgage:

maximum loan  $ 209, 371.16

interest paid     $  150,628.84

30 years mortage

maximum loan  $ 250,187.4216

interest paid     $  289,812.58

Explanation:

20 years mortgage:

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C 1,500.00

time 240 (20 years x 12 months)

rate 0.005 ( 6% annual / 12 months per year)

1500 \times \frac{1-(1+0.005)^{-240} }{0.005} = PV\\

PV $209,371.1575

Quota x number of cuotas - principal = total interest

1,500 x 240 - 209,371.16 = 150628.84

30 years mortgage

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C 1,500.00

time 360

rate 0.005

1500 \times \frac{1-(1+0.005)^{-360} }{0.005} = PV\\

PV $250,187.4216

Quota x number of cuotas - principal = total interest

1,500 x 360 - 250,187.42 = 289,812.58

If total change in cash = $44,000, net operating cash flows = $22,000, and net investing cash flows = ($13,000); then net financ
Mnenie [13.5K]

Answer:

Net financing cashflows are $ 35,000.

Explanation:

A company generates cashflow from three activities that are cash from operations , cash from financing activities and cash from investing activities. The company net cash flow is total of these above specified. So we can determine net financing cashflows from the equation given below.

<em>total change in cash = net operating cash flows + net investing cash flows + net financing cash flows</em>

net financing cash flows = $ 35,000

The _______ was a foreign policy embarrassment for the United States during the Kennedy Administration. 
mrs_skeptik [129]
The Bay of Pigs Invasion was a foreign policy embarrassment for the Kennedy Administration.
When John Kennedy assumed the presidency after Dwight Eisenhower, he was faced with the pressure to act on Cuban dictator Fidel Castro's growing relationship with the Soviet Union (yet another of US' formidable enemies).
His senior advisers urged him to authorize the attack on Cuba and initiate a movement to overthrow Fidel Castro. This played on Kennedy's foreign principle which is for Democratic countries such the US to show a strong force against dictatorships like Castro's. In April 1961, the invasion at the Bay of Pigs failed extremely. Castro was quick to mobilize his militia to counter Kennedy's botched plan. Aside from this, Kennedy made some worst decisions that nailed the coffin shut. Thus the Kennedy Administration suffered a lot of damage due to this failure.
