A. A fact that elaborates on the point of the writing.
The key difference between command and market economies is that: Households answer the basic economic questions in a market economy, while a group of leaders answer them in a command economy.
<h3>Types of economy.</h3>
Generally, there are five (5) main types of economy and these include the following;
- Mixed economy.
- Command economy.
- Traditional economy.
- Pure capitalism economy.
- Underground economy (black market).
<h3>What is a market economy?</h3>
A market economy is also referred to as free-enterprise system or free market and it can be defined as a type of economy in which prices, products and services are being determined by the market rather than the government.
This ultimately implies that, a market economy is devoid (free) of government regulations, interference or control because the market is completely driven by demand and supply of goods and services.

To find the displacement between t=0 and t=1, we want to plug 0 & 1 into the equations, then find the different in the answers.
<u>When t = 0:</u>
x = 4 cos(π(0)+π/4) → π · 0 = 0, so therefore:
x = 4 cos (π/4) → cos (π/4) = √2/2
x = 4 (√2/2)
x = 4√2/2 → 4 divided by 2 = 2, so we can simplify this to
x = 2√2
<u>When t = 1:</u>
x = 4 cos(π(1)+π/4) → π · 1 = π, so therefore:
x = 4 cos (π + π/4) → π + π/4 = 5π/4, so therefore
x = 4 cos (5π/4) → cosine of 5π/4 = -√2/2
x = 4 · -√2/2
x = -4√2/2 → -4 divided by 2 = -2, so we can simplify this to
x = -2√2
<u>Answer</u>: Then, we find the difference between x(0) and x(1), which is x(1)-x(0) =
-√2/2 - √2/2 = <u>-√2</u>
Answer:
first answer looks best
Explanation:
the government wanted to eliminate monopolies in business so they tried to encourage competition in the marketplace
