Answer:
(x + 5)² + (y - 7)² = 13
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 5, 7) and r = , thus
(x - (- 5))² + (y - 7)² = ( )² , that is
(x + 5)² + (y - 7)² = 13 ← equation of circle

Answer:
Unit rate of people per book = 2.5
Step by step explanation:
Given:
Number of peoples =
Number of books =
Their ratios =
We have to find the unit rate of people per book.
To find out the unit rate of people per book we have to divide the total number of peoples by the total number of books.
Or
For this we will follow the unitary method:
For book there are
persons.
For book there will be
persons.
So,
The numeric value =
=
There are 2.5 people per book and that it also the unit rate of people per book.
