Find the equation of the following ellipse based on the following information: Vertices: (-2,0), (2,0) minor axis of length 2​
Sav [38]

Answer:

The expression of the ellipse is: \frac{x^2}{4} + y^2 = 1

Step-by-step explanation:

The equation of a ellipse can be written by the following expression:

\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1

Where 2a is the length of the major axis and 2b is the length of the minor axi. Since we were given the length of the minor vertex, then:

2b = 2\\b = 1

The length of the major axis is the distance between the two vertices.

2a = \sqrt{[2 - (-2)]^2}\\2a = \sqrt{(2 + 2)^2}\\2a = \sqrt{4^2}\\2a = 4\\a = 2

Therefore the expression of the ellipse is:

\frac{x^2}{2^2} + \frac{y^2}{1^2} = 1\\\\\frac{x^2}{4} + y^2 = 1

What is the slope of a line perpendicular to the line whose equation is
kotykmax [81]

Answer:

slope = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + 2y = - 16 ( subtract x from both sides )

2y = - x - 16 ( divide all terms by 2 )

y = - \frac{1}{2} x - 8 ← in slope- intercept form

with slope m = - \frac{1}{2}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-\frac{1}{2} } = 2
