Answer: First option is correct.
Step-by-step explanation:
Since we have given that
PA = 22
PB = 22+40=62
PC = 26
PD = 26+d
As we know the rule of tangents :
PA.PB=PC.PD

Hence, First option is correct.
Answer:

Step-by-step explanation:
The Unemployment rate of a country is calculated as a fraction of its Labor force. In Barbaria,
Number of Unemployed =9 million
Number of Employed =35 Million
Labor Force = (9+35) Million =44 Million

The Unemployment rate in Barbaria in 2012 was 25.71%.
The vertex is the point where the function changes direction, in this case from growing to decrease. That is the point wiht x-coordinate 4 and y-coordinate 1, so the point is (4,1).
Solution:
we are given that
The state of New Jersey has a population of about 8.9 million and its area is about 8700 mi².
we have been asked to find the population density of New Jersey?
As we know the population density is defined as the population per square unit of area.
Population=8.9 million=8900000
Area=8700 mi².
Hence population density can be given as

The population density of New Jersey 1023.
