Answer:
What is a power grid?
C) Transmission lines and transformers that take and send electricity from generating facilities to end users
Explanation:
A power grid is a system of interconnected transmission lines and transformers that takes electricity from the producers to the consumers. The power grid is very important in the supply of electricity to consumers. Before power is to be transmitted to the consumers, it has to be generated. Traditionally, the conventional way of generating power was from central power stations that utilized sources like; fossil fuels, coal and natural gas. In the recent past, however, more advancements have been made towards more clean energy sources like; wind, geothermal and hydroelectricity. Clean energy sources have several benefits over the traditional sources of energy, like; they don't cause harm to the environment and also they are renewable since they can be used over and over without depletion.
Once the energy has been harnessed and converted to electricity, it needs to be transmitted. The network for transmission to the consumers is what makes up the power grid. Transmission is usually done at very high voltage to minimize losses. However, before providing it the consumers, the electricity needs to be converted to a low voltage by the use of transformers for domestic and commercial consumption.
Answer:
Break-even point= 7,900 new costumers
Explanation:
Giving the following information:
Assume that during a recent fiscal year, one outlet spent $1,659,000 on a promotional campaign for its website that offered two free months of service for new subscribers.
In addition, assume the following information: Number of months an average new customer stays with the service (including the two free months) 22 months Revenue per month per customer subscription $16 Variable cost per month per customer subscription $5.
Break-even point= fixed costs/ contribution margin
Fixed costs= 1,659,000
Contribution margin= (16*20)-(5*22)= 210
Break-even point= 1,659,000/210= 7,900 new costumers
<u>Solution and Explanation:</u>
Required Return after 5 year = Real rate of return + Inflation premium + Risk premium
Required Return after 5 year = 5+2+4
Required Return after 5 year =11%
No of year left to maturity = 25
Annual Interest payment = 15%*1000 = 150
Face value of Bond = 1000
New price of the bond = pv (rate, nper, pmt, fv)
New price of the bond = pv (11%,25,150,1000)
New price of the bond = $ 1336.87
