Answer:
So the center is at (20,.05) and the radius is 9
Step-by-step explanation:
The equation of a circle can be written in the form
(x-h) ^2 + (y-k) ^2 = r^2
where (h,k) is the center and r is the radius
Lets write our equation in that form
( x-20)^2 + (y-0.05)^2 =81
( x-20)^2 + (y-0.05)^2 =9^2
So the center is at (20,.05) and the radius is 9
Do 600÷12= 50
The answer is 50
Answer:
The positions of the vertex and the axis of symmetry change.
Step-by-step explanation:
Let’s examine three parabolas in which a and c remain constant and only b changes.
(1) y = x² - 2x + 1
(2) y = x² + 1
(3) y = x² + 2x + 1
In the image below,
Equation (1) is the black parabola, Equation (2) is green, and Equation (3) is red.
When b is more negative, the vertex moves down, and the axis of symmetry moves to the right.
When b is more positive, the vertex moves down, and the axis of symmetry moves to the left.
