Answer:
Center (6 , -5) and radius = 3
Step-by-step explanation:
The Standard equation of circle can be written as
(x - a)² + (y - b)² = r²
with center (a , b) and radius = r
Now from given circle equation
(x - 6)² + (y +5)² = 9
so, from here center of circle (6 , -5) and radius = 3

If x^2+bx+16 has at least one real root, then the equation x^2+bx+16=0 has at least one solution. The discriminant of a quadratic equation is b^2-4ac and it determines the nature of the roots. If the discriminant is zero, there is exactly one distinct real root. If the discriminant is positive, there are exactly two roots. The discriminant of <span>x^2+bx+16=0 is b^2-4(1)(16). The inequality here gives the values of b where the discriminant will be positive or zero:
b^2-4(1)(16) ≥ 0
</span><span>b^2-64 ≥ 0
(b+8)(b-8) </span><span>≥ 0
The answer is that all possible values of b are in the interval (-inf, -8]∪[8,inf) because those are the intervals where </span>(b+8)(b-8) is positive.
