The correct answer is second one
Answer:

Step-by-step explanation:
we know that
The graph of the figure represent a vertical parabola open upward
The vertex represent a minimum
The vertex of the quadratic equation is the point (h,k)
The range of the quadratic equation is the interval for y [k,∞)

Looking at the graph
The vertex is the point (0,-6)
therefore
The range is the interval [-6,∞)

9 feet = 108 inches
$9.72 divided by 108= 0.09
The discriminant of a quadratic equation is useful in determining the nature of its roots. Further, it can be solved by the equation,
D = b² - 4ac
From the given equation, b = 3, a = 2, and c = -5. Substituting the given to the equation,
D = 3² - (4)(2)(-5) = 49
Thus, the answer is the fourth choice, 49.
10/2 = 5.
Knowing this, all we have to do is multiply 19.8 by 5:
19.8 * 5 = 99
