The number of zeros of the quadratic functions, considering their discriminant, is given as follows:
- discriminant = 0: 1 Real number solution.
- discriminant = -36: 0 Real number solutions.
- discriminant = 3: 2 Real number solutions.
- discriminant = 2: 2 Real number solutions.
- discriminant = 100: 2 Real number solutions.
- discriminant = -4: 0 Real number solutions.
<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>
A quadratic equation is modeled by:
The discriminant is:
The solutions are as follows:
- If
, it has 2 real solutions.
- If
, it has 1 real solutions.
- If
, it has 0 real solutions.
Hence, for the given values of the discriminant, we have that:
- discriminant = 0: 1 Real number solution.
- discriminant = -36: 0 Real number solutions.
- discriminant = 3: 2 Real number solutions.
- discriminant = 2: 2 Real number solutions.
- discriminant = 100: 2 Real number solutions.
- discriminant = -4: 0 Real number solutions.

The -1 means that y = -1, so point is one unit below the x-axis. In (5, -1), the x is positive, which could put the point in either the first quadrant or the fourth. With the y being negative, however, it means that the point is in the fourth quadrant. Those are your 2 true statements.
Answer:
The previous number keeps getting multiplied by - 5
Step-by-step explanation:
5 × -5 = -25
-25 × -5 = 125
125× -5 = -625
-625 × -5 = 3,125
3125 × -5 = -15,625
-15,625 × -5 = 78,125
78,125 × -5 = -390, 625
-390,625 × -5 = 1,953,125
1,953,125 × -5 = 9,765,625

Answer:
5cm
Step-by-step explanation:
volume = πr²h
225π = π × r² × 9
225/9 = r²
r = √225/9 = 15/3 = 5cm
