An alternative to CFL bulbs and incandescent bulbs are light-emitting diode (LED) bulbs. A 100 W incandescent bulb can be replac

ed by a 16 W LED bulb. Both produce 1,600 lumens of light. Assuming the cost of electricity is $0.20 per kilowatt-hour, how much does it cost (in dollars) to run the LED bulb for one year if it runs for five hours a day?

Answer:

It cost $5.84 to run the LED bulb for one year if it runs for five hours a day.

Explanation:

E = Pt

  = (16W)(365*5)

  = 29200Wh

  = 29.2 kWh

cost of operation = E($0.2/kWh)

                             = (29.2 kWh)($0.2/kWh)

                             = $5.84

Therefore, It cost $5.84 to run the LED bulb for one year if it runs for five hours a day.

Suppose you buy a 7 percent coupon, 20-year bond today when it’s first issued. If interest rates suddenly rise to 15 percent, wh
Mariana [72]

Answer: The value of the bond will decrease

Explanation:

The Interest rate has a negative inverse relationship with the value of a bond . When the interest rate increases the value of a bond decreases and when interest rate decreases  the bond value increases. Bonds with low coupon rates tend to be more sensitive to interest rate changes this is known has coupon effect.

Bonds with long time frame (long term bonds), they also  tend to be are more sensitive to changes in the interest rate this is known has the maturity effect.  Therefore a change in the interest rate will cause a huge change in the value of a Bond with low coupon rate and long time period.

The Bond is a 20 year Bonds which qualifies it to be a long term bond and the coupon Rate is 7%, with these facts and knowing that  long term bonds are more sensitive to interest rate changes we can conclude that the sudden increase of the interest rate to 15%  will cause a huge decrease in the value of the bond

Using the following information, what is the amount of net income? Purchases $ 33,114 Selling expenses $ 677 Merchandise invento
NeX [460]

The net income is $32,961

<u>Explanation</u>:

To calculate the net income, we will classify the transaction into income and expenses, and compute the difference between their totals;

Income;

Merchandise inventory Sept. 1     =  $  7,740

Merchandise inventory Sept. 30  = $ 11,372

                                         Sales     =  $ 50,575

                                        Total      =  $ 69,687

Expenses;

Purchases                             = $ 33,114

Selling expenses                  = $     677

Administrative expense       = $     665

Rent Revenue                       = $    1,118

Interest expense                  = $     1,152

Total                                      = $  36,726

Net income = Total income - Total expenses

                    = 69,687 - 36,716

                    = $ 32,961

Mademuasel [1]

Answer:

p = 59.11 dollars

Explanation:

Given

Price:     p(x) = 8eˣ      (0 ≤ x ≤ 2)

Revenue;  R = x*p = 8xeˣ

p = ?  when R be at maximum

We can apply

dR/dx = d(x*p)/dx = 0

⇒  d(8xeˣ)/dx = 8*(1*eˣ + x*eˣ) = 0

⇒  eˣ*(1 + x) = 0    ⇒    x = - 1

as x = - 1 ∉ [0, 2]

then, we have

p(0) = 8e⁰ = 8

R = 0*8 = 0

If x = 1

p(1) = 8e¹ ≈ 21.74

R = 1*21.74 = 21.74

If x = 2

p(2) = 8e² ≈ 59.11

R = 2*59.11 = 118.22

Implies that, R(x) is maximum at x = 2.

   

Thus, the price that maximize the revenue of the company is 59.11 dollars.

Shawn will pay Craig with a negotiable instrument, and Shawn plans to involve a third party in that process. What instrument sho
masha68 [24]

The instrument that Shawn must use is “payable to the order of” before the name of the payee.

<h3>Requirements of Negotiability </h3>
  • The first of the four major considerations is whether or not a paper is negotiable, and it is one that nonlawyers must address.
  • Auditors, retailers, and financial institutions frequently handle notes and checks and must make quick decisions about negotiability.
  • In a negotiable instrument, the only permissible promise or direction is to pay a particular sum of money. Any other promise or command renders negotiability null and void
  • This restriction exists to prohibit an instrument from having an uncertain value.
  • If the bearer of a negotiable instrument had to examine whether a provision or condition had been met before the thing had any value, the utility of the object as a substitute for money would be severely diminished.

Hence, the instrument that Shawn must use is “payable to the order of” before the name of the payee.
