Managers often consider meta-models to improve their understanding of the absolute and relative potential of an economic environment. popular indices include:

Popular indices include:

1. Global Competitiveness Index.

2. Global Innovation Index.  

3. Where-To-Be-Born Index.

Explanation:

Managers study economic environment of a country to assess its performance and estimate the potential. Popular indices should include the following three things:

'Global Competitiveness Index' which is a report that would give an assessment of how productive a country is when using its available resources. This would then give an idea of how much a country will grow.

'Global Innovation Index' measures all the aspects of innovation and help provide the tools that would help in modifying policies so that the country's productivity is grown, there are more jobs and so on.

'Where-to-be-born index' measures the country's output on how it can provide best chances for a healthy and a safe life.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
