Answer:

Equation of the Ellipse is \frac{x^2}{21}+\frac{y^2}{25}=1

Step-by-step explanation:

Given:

Foci ( 0 , -2 ) and ( 0 , 2 )

y-intercept = -5 and 5

To find: standard form of the Equation of the ellipse.

Since, x-coordinate of the foci are 0.

⇒  Major axis of the Ellipse is y-axis.

⇒ Standard Equation of the ellipse,

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

Now, from y-intercept a = 5 and from foci, c = 2

⇒ c² = a² - b²

2² = 5² - b²

b² = 25 - 4

b² = 21

b = ± √21

So, equation is

\frac{x^2}{(\sqrt{21})^2}+\frac{y^2}{5^2}=1

\frac{x^2}{21}+\frac{y^2}{25}=1

Therefore, Equation of the Ellipse is \frac{x^2}{21}+\frac{y^2}{25}=1

The equation is asking to calculate the standard for of the equation of ellipse satisfying the given condition and in my further research and computation,  would say that the answer would be <span>x^2/21 + y^2/25 = 1. I hope you are satisfied with my answer and feel free to ask for more</span>

Graph this compound inequality 2.5 is equal to or less than x is equal to or less than 4.5
Oxana [17]

Graph this compound inequality 2.5 is equal to or less than x is equal to or less than 4.5

2.5 <= x < = 4.5

We graph this inequality using number line.

Here x lies between 2.5  and 4.5

While graphing, we start with closed circle at 2.5 because we have equal symbol .

Then shade till 4.5. Use closed circle at 4.5.

The graph is attached below.
