The graph of a hyperbola is shown. what are the coordinates of a focus of the hyperbola? (−12, 0) (0, −5) (0, 0) (13, 0)

Focus : ( 13, 0).

Step-by-step explanation:

Given : The graph of a hyperbola is shown.

To find : What are the coordinates of a focus of the hyperbola.

Solution : We have given that a hyperbola :

Foci for hyperbola is foci (c,0) and  (−c,0)

Focus : ( 13, 0)

Therefore, Focus : ( 13, 0).

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

ab will be equal to
