Answer:
See below
Step-by-step explanation:
Remember that quadratic functions are parabolas when graphed. The solutions are where the parabola crosses the x-axis.
1. The vertex of the parabola in f(x) is (0, 9) which is above the x-axis and the parabola opens up. So the parabola does not cross the x-axis. Therefore the solutions are imaginary.
2. The vertex of the parabola in g(x) is (9, 0) which is on the x-axis and parabola opens up. Therefore, there is a double solution.
3. The vertex of the parabola in h(x) is (-1, -9) which is below the x-axis and the parabola opens up. Therefore, there are two real solutions.
I know this is a long explanation, but that is a way of looking at the problem.
Answer:
Y axis is correct :))
Step-by-step explanation:
D. Give performers an unfair advantage
Let’s talk about option A; Drugs that athletes take (for e.g. steroids) they INCREASE athletes muscle mass & endurance. They look bigger & muscular than a normal natural athlete.
Option B is also incorrect because there is no drugs that are legal in sports
Option C - It increase the athletes performance and your extremely energetic. You are doing what an natural cannot do in a short period of time.
SO OPTION D - It’s unfair to the natural ones
Answer:
A) P = 6n + 8
Step-by-step explanation:
Given:
Perimeter of the 1 triangle = 24
Perimeter of the 2 triangle = 30
Perimeter of the 3 triangle = 36
Let's check with option A.
P = 6n + 18, where "n" is the number in the figure.
Plug in n = 1, we get
P = 6(1) + 18
= 6 +18
P = 25 True.
Plug in n =2, we get
P = 6(2) + 18
= 12 +18
P = 30 True.
Plug in n =3, we get
P = 6(3) + 18
P = 18 + 18
P = 36, true.
Therefore, the answer is A. P = 6n + 18
Thank you.
