Which statements describe effects of changes in information technology? check all that apply. 1) economists are better able to predict how resources should be allocated. 2) governments can make better economic policy decisions. 3) it has become more difficult for businesses to identify when shortages will occur. 4) the amount of time to share data between locations has steadily increased. 5) employment in information technology sectors has grown.

The answer is:

1) Economists are better able to predict how resources should be allocated.

2) Governments can make better economic policy decisions.

5) Employment in information technology sectors has grown.

Due to the changes, economists find it easier to collect the data regarding resource usage and availbility. This make their prediction regarding resource allocation better.

Using the data from the economists along with open communication with the public, governments would find it easier to make better economic policy.

Separated form the two effects, employment in information technology sectors would grown since many other sectors can definitely apply the advancement in information technology to increase their performance.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
