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:
$66.9725
Explanation:
Data provided in the question:
Dividend:
D1 = $1.20
D2 = $1.40
D3 = $1.55
Expected future price, P3 = $82
Required return = 8.9 percent = 0.089
Now,
Stock price today = Present value of dividends and the future value
Stock price today = 
or
Stock price today = 1.1019 + 1.1805 + 1.2001 + 63.49
or
Stock price today = $66.9725

A series of markets where goods and services are exchanged, facilitated by capital, combine to make an economy. These networks exist at a local, national and global level. Economies can take many exclusive forms, focus on various priorities, and feature distinct levels of government intervention.
Financial issues influence our everyday lives. This consists of problems such as tax and inflation, interest rates and wealth, inequality and emerging markets, and energy and the environment. Economic systems can be categorized into four major types: traditional economies, command economies, mixed economies, and market economies.
