Answer:
<h3>2√3</h3>
Step-by-step explanation:
The standard equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the center of the circle
r is the radius of the circle
Given the equation (x - 7)^2 + (y + 13)^2 = 12
On comparing;
r² = 12
Take the square root of both sides
√r² = √12
r = √12
r = √4*3
r = 2√3
Hence the radius of the circle is 2√3
No, because using the vertical line test, two points touch on the same line
[3, 3]
[3,4]
In polar coordinates, the axis determined by theta=0 is called the
positive x-axis or horizontal axis.
To add, in mathematics, the polar coordinate<span> system is
a two-dimensional </span>coordinate<span> <span>system in
which each point on a plane is determined by a distance from a reference point
and an angle from a reference direction.</span></span>
Answer:
300
Step-by-step explanation:
The total number of ratio units in 6:5 is 6+5=11, so each of those ratio units must stand for 550/11 = 50 detectives. Then the 6 ratio units of police detectives stand for 6·50 = 300 police detectives.
It is 76
