gen. Equation is...
x²/a² - y²/b² =1
a=length from origin to vertex
a=2
b=length from origin to focus
b=9
so equation is
x²/2² - y²/9² =1
-> (x²/4) - (y² /81) =1
Hope it helps...

Step-by-step explanation:
The graph of y = tan x is shown. We need to find what y equals when x = 0 (because in y = tan 0, x is replaced with 0)
So you can either find where x = 0 on the graph, or you can take the tangent of 0 to find your answer.
The answer is 45-40=5 students are in band
