Find the Vertices ((y-21)^2)/(20^2)-((x+20)^2)/(21^2)=1

$\frac{{(y - 21)}^{2}}{20^{2}} - \frac{{(x + 20)}^{2}}{21^{2}} = 1$

Step 1

Simplify each term in the equation in order to set the right side equal to $1$ . The standard form of an ellipse or hyperbola requires the right side of the equation be $1$ .

$\frac{{(y - 21)}^{2}}{400} - \frac{{(x + 20)}^{2}}{441} = 1$

Step 2

This is the form of a hyperbola. Use this form to determine the values used to find vertices and asymptotes of the hyperbola.

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

Step 3

Match the values in this hyperbola to those of the standard form. The variable $h$ represents the x-offset from the origin, $k$ represents the y-offset from origin, $a$ .

$a = 20$

$b = 21$

$k = 21$

$h = - 20$

Step 4

Find the vertices.

The first vertex of a hyperbola can be found by adding $a$ to $k$ .

$(h, k + a)$

Substitute the known values of $h$ , $a$ , and $k$ into the formula and simplify.

$(- 20, 41)$

The second vertex of a hyperbola can be found by subtracting $a$ from $k$ .

$(h, k - a)$

Substitute the known values of $h$ , $a$ , and $k$ into the formula and simplify.

$(- 20, 1)$

The vertices of a hyperbola follow the form of $(h, k \pm a)$ . Hyperbolas have two vertices.

$(- 20, 41), (- 20, 1)$

Step 5

Find the Vertices ((y-21)^2)/(20^2)-((x+20)^2)/(21^2)=1
