Answer:
63 books per capita in the library
<em></em>
Step-by-step explanation:
Given
![Books = 2.73 * 10^3](https://tex.z-dn.net/?f=Books%20%3D%202.73%20%2A%2010%5E3)
![People = 43](https://tex.z-dn.net/?f=People%20%3D%2043)
Required
Determine the book per capita
To do this, we simply divide the number of books by number of person;
![Average = \frac{Books}{People}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cfrac%7BBooks%7D%7BPeople%7D)
![Average = \frac{2.73 * 10^3}{43}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cfrac%7B2.73%20%2A%2010%5E3%7D%7B43%7D)
![Average = \frac{2.73 * 1000}{43}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cfrac%7B2.73%20%2A%201000%7D%7B43%7D)
![Average = \frac{2730}{43}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cfrac%7B2730%7D%7B43%7D)
![Average = 63.488372093](https://tex.z-dn.net/?f=Average%20%3D%2063.488372093)
(Approximated)
Hence;
<em>There are 63 books per capita in the library</em>

Answer:
Step-by-step explanation:
Review the standard equation of a circle with center at (h, k) and radius r:
(x - h)^2 + (y - k)^2 = r^2
A point on (4, -2) has the radius r^2 = (4)^2 + (-2)^2, or r^2 = 20, or r = 2√5. Knowing the center is at (0, 0), we can write:
x^2 + y^2 = 20, or x^2 + y^2 = (2√5)^2
4/3.2 = 7/x
4x = 22.4
/4
x = 5.6
