Hello :
<span>(x - 3)² + y² = 7²
the center is : A(3 , 0 ) and radius r = 7
the </span> point D is on the interior if : AD <span>< 7
</span>the point D is on the exterior if : AD > 7
the point D is circumference of the circle if :AD = 7
It is missing some parts in the question
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.
I would say the answer is the first option. Usually when it asks for opposites, it wants something like the opposite of 15 is -15. Putting a negative on the outside means you solve the same, but you just add a negative sign on the number,
