Domain is x>1 or x<1 vertical asy y=1
Check the picture below, so the hyperbola looks more or less like that.
based on the provided vertices, its center is at the origin, as you see there, the "a" component or traverse axis is 4, the "c" distance is 5.

Answer:
25 degrees
Step-by-step explanation:
Angles 4 and 6 are supplementary angles since they as same side interior angles for parallel lines cut by a transversal. This means angle 4 + angle 6 = 180. If angle 6 is 155 then angle 4 must be 25 degrees
(percent change) = ((new value)/(old value) -1)*100%
.. = (1190/850 -1)*100%
.. = 40%
The coin was sold for a price 40% higher than its purchase price.
