Describe the impact a rapidly growing economy can have on families.

Answers

Economic growth is the most powerful instrument for reducing poverty and improving the quality of life in developing countries. Both cross-country research and country case studies provide overwhelming evidence that rapid and sustained growth is critical to making faster progress towards the Millennium Development Goals – and not just the first goal of halving the global proportion of people living on less than $1 a day.
Growth can generate virtuous circles of prosperity and opportunity. Strong growth and employment opportunities improve incentives for parents to invest in their children’s education by sending them to school. This may lead to the emergence of a strong and growing group of entrepreneurs, which should generate pressure for improved governance. Strong economic growth therefore advances human development, which, in turn, promotes economic growth.
But under different conditions, similar rates of growth can have very different effects on poverty, the employment prospects of the poor and broader indicators of human development. The extent to which growth reduces poverty depends on the degree to which the poor participate in the growth process and share in its proceeds. Thus, both the pace and pattern of growth matter for reducing poverty.
A successful strategy of poverty reduction must have at its core measures to promote rapid and sustained economic growth. The challenge for policy is to combine growth- promoting policies with policies that allow the poor to participate fully in the opportunities unleashed and so contribute to that growth. This includes policies to make labour markets work better, remove gender inequalities and increase financial inclusion.
Asian countries are increasingly tackling this agenda of ‘inclusive growth’. India’s most recent development plan has two main objectives: raising economic growth and making growth more inclusive, policy mirrored elsewhere in South Asia and Africa.
Future growth will need to be based on an increasingly globalised world that offers new opportunities but also new challenges. New technologies offer not only ‘catch-up’ potential but also ‘leapfrogging’ possibilities. New science offers better prospects across both productive and service sectors.
Future growth will also need to be environmentally sustainable. Improved management of water and other natural resources is required, together with movement towards low carbon technologies by both developed and developing countries. With the proper institutions, growth and environmental sustainability may be seen as complements, not substitutes.
DFID will work for inclusive growth through a number of programmes and continues to spend heavily on health and education, which have a major impact on poor people’s ability to take part in growth opportunities.
More and better research on the drivers of growth will be needed to improve policy. But ultimately the biggest determinants of growth in a country will be its leadership

Growth in the economy boosts state capacity and the availability of public goods. The capacity and resources required to deliver the public goods and services that their population requires, such as healthcare, education, social protection, and fundamental public services, are gained when economies grow and states are able to tax that revenue.

What impact economic growth has?

The most effective means of eradicating poverty and raising the standards of living in developing nations is economic growth. Growth can create beneficial cycles of wealth and opportunity. Parents are more motivated to make an investment in their children's education by sending them to school when there is strong growth and career opportunities.

Asian nations are focusing more and more on the "inclusive growth" agenda. Asian nations are focusing more and more on the "inclusive growth" agenda. In South Asia and Africa, similar policies to those in India's most recent development plan have two key goals: increasing economic growth and making progress more inclusive.

If the Juan de Fuca Plate continues to move away from the Pacific Plate at the same speed as shown on the graph, how many meters will it move in 10,000 years?

Answers

The distance that Juan de Fuca Plate would move is 290 meters.

Note: The Juan de Fuca Plate is moving southeast away from the Pacific Plate at a speed of 29 mm/year.

Given the following data:

Speed = 29 mm/year.Time = 10,000 years.

To determine the distance that Juan de Fuca Plate would move in meters:

First of all, we would convert the value in millimeters (mm) to meters (m) as follows;

Conversion:

1 millimeter = 0.001 meter

29 millimeter = X meter

Cross-multiplying, we have:

[tex]X = 0.001 \times 29[/tex]

X = 0.029 meter.

Speed = 0.029 meter/year.

Mathematically, the distance covered by an object is given by this formula:

[tex]Distance = speed \times time[/tex]

Substituting the given parameters into the formula, we have;

[tex]Distance = 0.029 \times 10000[/tex]

Distance = 290 meters.

What is a stereotype?

A stereotype is a fixed, overly generalized view about a certain group or class of individuals that is used in social psychology. Stereotyping implies that an individual possesses a wide range of traits and skills that we presume all members of that group possess. For instance, a "hells angel" biker wears leather clothing.

A stereotype has the benefit of allowing us to react quickly to circumstances since we may have previously encountered something similar.

One drawback is that it encourages us to disregard individual differences, which leads us to form assumptions about others that may not be accurate (i.e. make generalizations).

O A bias towards presenting news that is critical of local businesses.
O A bias towards presenting news that is of little interest to the middle class.

Answers

Explanation:

Answer:

Explanation:

Another way that news can be biased is an overemphasis on issues that affect middle class viewers and an underemphasis on issues that affect poorer viewers. Often, this is intentional.

It all has to do with advertisers who aren't particularly interested in news programming that attracts viewers who don't have the money to buy products. For example, news coverage of a bus strike might focus more on the impact of the strike on middle class viewers, who are relieved that traffic hasn't been affected by the strike, than they do for poorer viewers, who depend exclusively on buses and who have been impacted very negatively by the strike.

Kievan Rus is used to refer to a loose federation of East Slavic, Baltic and Finnic peoples. Before King Vladimir brought Christianity to this East Slavic area, the Kievan Rus practiced traditional Baltic, Slavic, and Finnish religions.

In order to strike auspicious military and economic alliance with the Byzantine people, King Vladimir decided to embrace and introduce Christianity, inviting his people to be baptized as Christians.
