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:
Stock Y has overvalued and Stock Z as undervalued
Explanation:
In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below
Expected rate of return = Risk-free rate of return + Beta × (Market rate of return - Risk-free rate of return)
For Stock Y
= 4.85% + 1.40 × 7.35%
= 4.85% + 10.29%
= 15.14%
For Stock Z
= 4.85% + 0.85 × 7.35%
= 4.85% + 6.2475%
= 11.0975%
The (Market rate of return - Risk-free rate of return) is also called market risk premium and the same is applied in the answer
As we see the expected return of both the stock So, Stock Y has overvalued and Stock Z as undervalued
Answer:
D ; increase growth
Explanation:
The discount rate is one of the tools that the Federal Reserve uses to direct monetary policy. Banks are subject to minimum reserves requirements. If a bank falls below this minimum, it can borrow from the banks with a surplus, or borrow from the federal reserve. If it borrows from the Fed, the interest rate that applies is the discount rate. The discount rate is always higher than the fed fund rate; hence, banks use it as a last resort.
The discount rate and the fed rate have similar effects on the economy. The Fed uses the discount rate to regulate the money supply in the country. When the growth in slow, the fed will reduce the discount rate. A low discount rate means the cost of borrowing money goes down. The impact is that individuals and businesses will afford to borrow money for consumption and investment.
Increased levels of investments and consumption will mean a higher GDP, which is growth.
