Answer:
Step-by-step explanation:
The general formula for a horizontal hyperbola :

Given: a = 1 we know a² = 1 ,and that c = 9 so we know c² = 9² = 81
We also know that the relation between a, b, c for a hyperbola is c²= a²+b²
c²= a²+b², substitute what we know
81 = 1 +b², subtract 1 from both sides of the equation
80 = b²
The equation of our hyperbola is:
or 
Answer:
The Colosseum.
Step-by-step explanation:
Answer:
solution given:
5x+2y=-6
as we know that slope intercept form is
y=mx+c
so
making above equation like that
2y=-5x-6
<u>y=-5/2x-3 is a slope intercept form</u>
The diffrence before he ascends is 3.
then 34-21=13 31-13=18
the diffrence is 18 feet after
