B. "rolling a 3 on a die and getting heads on a coin toss"
8n-2n=12
subtract the n’s: 8n-2n= 6n
then divide both sides by 6: 6n/6= 12/6
the 6 with the n and the six that’s in the denominator cancel out then divide 12 by six so: n= 2
The equation in rectangular coordinates. (x - 1)² + y² = 1
<h3>What are different Coordinate Systems ?</h3>
There are many types of coordinate system depending upon the usage and ease of working , Spherical , Rectangular , Cylindrical , Polar are the examples of Coordinate System.
It is given that the equation in polar coordinates is r = 2 cosθ
To change in rectangular coordinates
The relation between polar and rectangular coordinate is
x = r cosθ and y = r sinθ
x² + y² = r²
r = 2 cosθ
r² = 2r cosθ
r² = x
so the equation in rectangular coordinate system becomes
x² + y² = 2x
x² - 2x + y² = 0
x² - 2x + 1 + y² - 1 = 0
(x - 1)² + y² = 1
This represents the equation in rectangular coordinates.

Answer:
65 yards.
Step-by-step explanation:
The answer is 65 yards because 1 yard is 36 inches and 2340 divided by 36 is 65.
Answer:
First, plot your circle. the Center is (0, 3) and the radius is
Now to find your slope move from the (0, 3) to (5, 0)
The slope of a perpendicular line is opposite and reciprocal, so the slope is
The equation of our line tangent to the circle at the point (5, 0) is
Now substitute in the point (5, 0) to solve for b
Therefore, the equation of the line tangent to the circle is
