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.

Find the surface area of the rectangular prism.
Nataly_w [17]

Answer:

130 ft^2

Step-by-step explanation:

SA= surface area

SA= 2*l*w + 2*l*h + 2*w*h

l= length = 10

w= width =5

h = height = 1

SA= 2*l*w + 2*l*h + 2*w*h

SA= 2*10*5 +2*10*1+2*5*1

SA= 100+20+10

SA= 130 ft^2

The cylindrical container is four-fifths full of powder. Round to the nearest tenth if necessary. a. The total capacity of the c
mezya [45]

Answer:

a. \pi r^2h

b. \frac{4\pi r^2h}{5}

Step-by-step explanation:

Volume of the container denotes its quantity. It is a three-dimensional space.

Let V denotes the volume of the container, h denotes the height of the container and r denotes the radius of the container.

a.

The total capacity of the container in terms of π is \pi r^2h<u />

b.

As the cylindrical container is four-fifths full of powder, so the volume of the powder in terms of π is \frac{4}{5}\times volume of the container i.e., \frac{4\pi r^2h}{5}
