Step-by-step explanation:
<u>Graph of the Parabola</u>
The quadratic function's graph is called a parabola. There is a clear relationship between the roots of the equation and the shape of the parabola.
If the equation has two real roots, the parabola has two x-intercepts. If the equation has only one real root, the parabola crosses the x-axis only once, and if the equation has no real roots, the parabola never crosses the x-axis.
If the equation of the parabola is
Then the so-called discriminant is
If the discriminant is zero, the equation has only one real root. The graph in the image only goes through the x-axis once.
Thus, the correct answer is
D. is zero
Answer: Quadratic
Step-by-step explanation:
8.) A cube has 6 sides if you roll it 600 times then you have the chance of landing on 6 or 3 you would be landing on 3 or 6 200 times. ( 2/6 times by 600)
9.)The usage differs among different disciplines. In statistics probability can be thought of as the inherent chance of something happening, whereas frequency is the observed number of times it has happened, divided by the number of observations.
Answer:
26.4074
Step-by-step explanation:
r^2 = 2.9^2 = 8.41
Pi = 3.14
A = Pi * r^2
= 3.14 * 8.41
= 26.4074
