Question

Find an equation in standard form for the ellipse with the vertical major axis of length 18 and minor axis of length 16.

The options are:
x squared divided by sixty four plus y squared divided by eighty one = 1
x squared divided by nine plus y squared divided by eight = 1
x squared divided by eighty one plus y squared divided by sixty four = 1
x squared divided by eight plus y squared divided by nine = 1

Answer 1

what is half of 18?

Answer 2

after you get that, square it '
that is the number under the \(x^2\) term

Answer 3

So 81?

Answer 4

\[\frac{x^2}{81}\] is the first term, yes

Answer 5

So the answer is C

Answer 6

as always, yes

Answer 7

Answer 8

An elliptical riding path is to be built on a rectangular piece of property, as shown below.

A vertical ellipse is shown centered on the coordinate plane, surrounded by a rectangle of equal length and width.

The rectangular piece of property measures 10 miles by 8 miles. Find an equation for the ellipse if the path is to touch the center of the property line on all 4 sides. @satellite73
