Which of the following is the standard equation of the ellipse with vertices at (1,0) and (27,0) and an eccentricity of 5/13?

Dovator [93]

The equation of the elipse is given by:

$\frac{(x - 14)^2}{169} + \frac{y^2}{144} = 1$

The equation of an elipse of center $(x_0, y_0)$ is given by:

$\frac{(x - x_0)^2}{a^2} + \frac{(y - y_0)^2}{b^2} = 0$

Values a and b are found according to the <u>vertices and the eccentricity</u>.

It has vertices at (1,0) and (27,0), thus:

$x_0 = \frac{27 + 1}{2} = 14$

$y_0 = \frac{0 + 0}{2} = 0$

$a = \frac{27 - 1}{2} = 13$

$a^2 = 169$

It has eccentricity of $\frac{5}{13}$ , thus:

$\frac{5}{13} = \frac{c}{a}$

$\frac{5}{13} = \frac{c}{13}$

$c = 13$

Thus, b is given according to the following equation:

$c^2 = a^2 - b^2$

$b^2 = a^2 - c^2$

$b^2 = 169 - 25$

$b = \sqrt{144}$

$b = 12$

The equation of the elipse is:

$\frac{(x - 14)^2}{169} + \frac{y^2}{144} = 1$

I NEED HELP ASAP PLZZZZ

KonstantinChe [14]

Step-by-step explanation:

We just subsitue 3 for x and -4 for y, so we get

$3(3) - 5( - 4) = 9 + 20 = 29$

So

$a = 29$

$7(3) + ( - 4) = b$

$21 - 4 = 17$

$b = 17$

Find the function !!! 10 points - Help needed!

Arte-miy333 [17]

<h2>Hello!</h2>

The answer is:

The first option,

$f^{-1}(x)=\frac{x-2}{4}$

<h2>Why?</h2>

To find the inverse of a function, we need to rewrite the variable "x" with "y" and the variable "y" with "x", and then, isolate "y".

We are given the function:

$f(x)=4x+2$

Write "f(x)" is equal to write "y", so:

$y=4x+2$

Now, finding the inverse, we have:

$y=4x+2\\x=4y+2\\x-2=4y\\y=\frac{x-2}{4}$

Hence, we have that the answer is the first option,

$f^{-1}(x)=\frac{x-2}{4}$

Have a nice day!
