-Dominant- [34]

Answer:

1. AB is a diameter. (False)

2. ST, SP and SQ are radii. (True)

3. SQ = 12 cm. (False)

4. PQ is 12 cm. (True)

Step-by-step explanation:

1. AB is not a diameter because a diameter must pass through the center of the circle.

2. ST, SP and SQ are radii because they all meet at the center of the circle.

3. SQ is not equal to 12 cm. SQ is equal to 6 cm because it is a radius.

4. PQ is equal to 12 cm because it is a diameter. Radius = 6 cm. Diameter = 2 × radius = 2 × 6 cm = 12 cm

Make a comparison between the government’s roles in a capitalist economic system versus a socialist or communist economic system
Masteriza [31]
Hello!

In a Capitalist Economic System, the government is expected to guarantee the respect to private property, promulgate laws that defend economic freedom, and is an intermediary between the private sector and society. In this economic system, the government is reduced an doesn't intervene in the free market. 

In a Socialist or Communist Economic System, the government redistributes goods and services, takes the means of production (private property) from their owners to put them in service of the working class, promulgate laws that limit economic freedom and heavily intervenes in the market and economy.

Have a nice day!
