Answer:
A) 
Step-by-step explanation:
The equation of a circle is 
where 
is the center and 
is the radius. If 
and 
, then:
Therefore, the equation of the circle is
The correct representation of 6 + 2n > 12 (n > 3) is (3, ∞) and a number line with an open circle at +3 and being shaded from +3 to +5.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given the equation::
6 + 2n > 12
Subtracting 6 from both sides:
6 + 2n - 6 > 12 - 6
2n > 6
Dividing by 2:
n > 3
The correct representation of 6 + 2n > 12 (n > 3) is (3, ∞) and a number line with an open circle at +3 and being shaded from +3 to +5.

Answer:
16. -16 17. 15
Step-by-step explanation:
16. Plug in the numbers based on the equation.
-3^2+-2(-3+2)-3^2 = 2
17. Add up the lengths to get the perimeter.
2+2+2+6+3 = 15
Answer:
1. True
2. True
3. y = -1
4. False
Step-by-step explanation:
1 -------------------------
sin(-90) = -1
sin(270) = -1
True
2 --------------------------
y = cos(-90)
y = 0
True
3 -------------------------
y = tan(-45)
y = -1
-1
4 ---------------------------
tan(90) cannot be calculated
False
