Answer:
Value of x maximising profit : x = 5
Explanation:
Cost : C(x) = x^3 - 6x^2 + 13x + 15 ; Revenue: R(x) = 28x
Profit : Revenue - Cost = R(x) - C(x)
28x - [x^3 - 6x^2 + 13x + 15] = 28x - x^3 + 6x^2 - 13x - 15
= - x^3 + 6x^2 + 15x - 15
To find value of 'x' that maximises total profit , we differentiate total profit function with respect to x & find that x value.
dTP/dx = - 3x^2 + 12x + 15 = 0 ► 3x^2 - 12x - 15 = 0
3x^2 + 3x - 15x - 15 = 0 ► 3x (x +1) - 15 (x + 1) = 0 ► (x+1) (3x-15) = 0
x + 1 = 0 ∴ x = -1 [Rejected, production quantity cant be negative] ;
3x - 15 = 0 ∴ 3x = 15 ∴ x = 15/3 = 5
Double derivate : d^2TP/dx^2 = - 6x + 12
d^2TP/dx^2 i.e - 6x + 12 at x = 5 is -6(5) + 12 = - 30+ 12 = -8 which is negative. So profit function is maximum at x = 5
Answer:
$91,100
Explanation:
Calculation to determine the total cost of merchandise purchased
Using this formula
Total cost of merchandise purchased = Invoice cost of merchandise purchases + Cost of transportation in - Purchase returns and allowances - Purchase discount
Let plug in the formula
Total cost of merchandise purchased= $100,000 + $500 - $400 - $9,000
Total cost of merchandise purchased= $91,100
Therefore the total cost of merchandise purchased is $91,100
Is the multiple chose in it right or nah? <span />
The answer is: averaged over time, Sheridan attends worship services regularly.
When we use principle of aggregation, we would not rely on single measurement to make a representation of a person's behavior. We rely more on multiple sets of measurements.
From the case above, Sheridan not attending the services for two weeks could be explained by things such as personal issues or physical illness. Since she considers herself as religious who attend regularly, it is very likely that averaged over time, Sheridan attends worship services regularly.
Question
you are a consultant to a firm evaluating an expansion of its current business. The cash flow forecasts (in millions of dollar) for the project as follows:
Year cashflow
0 -100
1-10 15
0n the basis of the behavior of the firm's stock, you believe that the beta of the firm is 1.30. Assuming that the rate of return available on risk-free investments is 5% and that the expected rate of return on the market portfolio is 15% what is the net present value of the project
Answer:
NPV= -$32.58
Explanation:
The net present value of the investment is the cash inflow from the investment discounted at required rate of return. The required rate of return can be determined using the the formula below:
Ke= Rf +β(Rm-Rf)
Ke =? , Rf- 5%,, Rm-15%, β- 1.30
Ke=5% + 1.30× (15-5)= 18%
The NPV = Present value of cash inflow - initial cost
= A×(1-(1+r)^(-10)/r - initial cost
A- 15, r-18%
NPV = 15× (1-1.18^(-10)/0.18 - 100= -32.58
NPV = -$32.58
