1 answer:

3 0

The axis of symmetry of a parabola is the vertical line passing through its vertex. Given a parabola $ax^2+bx+c=0$ , the vertex x-coordinate can be found using

$x = -\dfrac{b}{2a}$

In your case, the formula leads to

$x = -\dfrac{40}{10} = -4$

So, this parabola is symmetric with respect to the line $x = -4$

What is the center of a circle represented by the equation (x 9)2 (y−6)2=102? (−9,6) (−6,9) (6,−9) (9,−6)

Korvikt [17]

The center of the circle (x + 9)² + (y − 6)² = 10² is at (-9, 6) and the radius of the circle is 10 units.

<h3>What is a circle?</h3>

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The equation of the circle is given as

(x + 9)² + (y − 6)² = 10²

Then the center of the circle is at (-9, 6) and the radius of the circle is 10 units.
