Which conic section does the equation below describe?
Rus_ich [418]

Answer: Option C. Ellipse

Step-by-step explanation:

The general equation of an ellipse has the following form:

\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1

Where the point (h, k) is the center of the ellipse

In this case we have the equation

\frac{(x-9)^2}{4} + \frac{(y+2)^2}{25} =1

Note that its shape matches that of a ellipse with center (9, -2)

a=\sqrt{4} \\a=2\\\\\\b=\sqrt{25}\\b=5

Therefore the answer is the obtion C

The pool is located at (0,0) to get to your house from the pool you walk three blocks west and one block north what ordered pair
ira [324]

Answer:

(-3, 1) quadrant II (2)

Step-by-step explanation:

An image of the coordinate plane is show.  The quadrants start at the top right and move around in the counter-clockwise direction.  The x-axis is horizontal (side to side) and y-axis is vertical (up and down).  Starting at the origin of the coordinate plane (0, 0) and going three blocks west (left) would put you at -3 on the x-axis.  If you then proceed to go north (up) +1, you would now be at point (-3, 1) which is a (-x, +y)  or in quadrant II.
