<h2>Circumference of circle 1 : Circumference of circle 2 = 1 : 2</h2>

Step-by-step explanation:

Circumference of a circle = πD, where D is the diameter.

Diameter of circle 1 = 1.125

Circumference of circle 1 = π x 1.125

Diameter of circle 1 = 2.25

Circumference of circle 1 = π x 2.25

\texttt{Ratio of circumferences = }\frac{\pi \times 1.125}{\pi \times 2.25}\\\\\texttt{Ratio of circumferences = }\frac{1}{2}

Circumference of circle 1 : Circumference of circle 2 = 1 : 2

What is the type of conic section given by the equation x^2 - 9y^2 = 900 and what is the domain and range?
Valentin [98]
A conic section is a curve obtained by the intersection of the surface of a cone with a plane. A conic section can be a circle, a hyperbola, a parabola, and an ellipse.

For a circle, the general equation of a circle with center, (a, b), and a radius, r, is of the form
(x-a)^2+(y-b)^2=r^2

For a hyperbola, the general equation of a hyperbola with center (h, k), and a and b half the lengths of the major and the minor axis respectively is of the form.
\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} =1

For a parabola, the general equation of a parabola with center (h, k), and a multiplier a is of the form
y-k=a(x-h)^2

For an ellipse, the general equation of an ellipse with center (h, k), and a and b half the lengths of the major and the minor axis respectively.
\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1

Given the equation
x^2-9y^2=900
It can be rewritten as
\frac{(x-0)^2}{900} - \frac{(y-0)^2}{100} =1 \\  \\ \frac{(x-0)^2}{30^2} - \frac{(y-0)^2}{10^2} =1
This gives an equation of a hyperbola with center (0, 0), half the length of the major axis = 30 and half the length of the minor segment = 10.

The domain of the equation is all real values of x.

Helppppppp pleaseeeeee
ANEK [815]

All you have to do is plug in the number for x, and find y. I will write this out as if in that chart you have shown.

x                            y = 9 - 3x                                    y

_______________________________________

0                           y = 9 - 3(0)                                  9

1                            y = 9 - 3(1)                                   6

2                           y = 9 - 3(2)                                  3

3                           y = 9 - 3(3)                                  0


Hope that helps!!
