Answer:
Step-by-step explanation:
Since G(0) = g(0) = 20, the parabolic graphs of these functions share a y-intercept: (0, 20).
Completing the square puts these equations into vertex form, which simplifies comparisons of the graphs:
G(x) = 2x^2 - 12x + 20 becomes
2(x^2 - 6x + 9 - 9) + 20, or
2(x - 3)^2 - 18 + 20, or 2(x - 3)^2 + 2. Comparing this result to
a(x - h)^2 + k, we see that the vertex is located at (3, 2).
Going through the same process for g(x) 2x^2+12x+20, we get:
g(x) = 2(x + 3)^2 + 2, whose vertex is at (-3, 2).

Answer:
The answer is C=942.48
Step-by-step explanation:
You would figure this out by using the formula C=2πr.
So let's break this down.
Circumference (C) equals (=) pi (π) times 2 times the radius of the circle.
Since the problem gave you the diameter which is the length from one side of the circle to the other, you have to divide the diameter in half. Which would give you a radius of 150.
Taking the 150 you would multiply 10*2*π.
Which would give you....(drumrollllll)
C=942.48
I hope this helps!!

Answer: C is correct, 4x=8
Step-by-step explanation:
You will add the two equations...
4x-8=0
Now you need to move the -8 over, which reverses its sign to positive.
4x=8
