The true question should be like this:
<span>What is the center and radius of the following circle: x^2 + (y _ 6)^2 = 50,
circle quation formula is (x-a)^2 + (y-b)^2 = R², so by identifying each term, we find </span>(x-a)^2=x^2 = (x-0)^2, (y-b)^2= (y _ 6)^2, R² = 50, implies R =5sqrt(2),
it is easy to identify that the center is (a,b)= (0, 6)
the radius is R =5sqrt(2),
Answer:
20 sides.
Step-by-step explanation:
The external angles of a polygon sum to 360 degrees.
So it's 360/18 = 20.

Answer:
<em>-11, -10, -9, -8, -7, -6 and -5 </em>
Step-by-step explanation:
Given the inequality expressions
2x+9<0 and x>-12
2x+9<0
2x< 0-9
2x < -9
x < -9/2
x < -4.5
Since x >-12
-12 < x
Combining both inequalities
-12 <x < 4.5
<em>The integers between the intervals are -11, -10, -9, -8, -7, -6 and -5 </em>
