Answer:
it means that the roots of the quadratic equation is real and distinct and that means that 40 is a positive value
It is 10.7703296143, but estimated it would be about 11. Hope I helped!! :)
A parabola is a mirror-symmetrical planar curve that is nearly U-shaped. The vertex of the parabola will lie at (-3,2).
<h3>What is the Equation of a parabola?</h3>
A parabola is a mirror-symmetrical planar curve that is nearly U-shaped.
y = a(x-h)² + k
where,
(h, k) are the coordinates of the vertex of the parabola in the form (x, y);
a defines how narrower is the parabola, and the "-" or "+" that the parabola will open up or down.
Comparing the given equation with the equation of a parabola, we will get,
y = a(x -h)² + k
y = -4(x+3)² + 2
Hence, the vertex of the parabola will lie at (-3,2).

Answer:
$50.00
Step-by-step explanation:
I did this. 18.95+2.95+15.64+5+7.46. It equaled 50 so fifty dollars is your answer.
15x1000+4x100+9x1
I belive that is edpanded notation.
