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...

∠A = 180° - B - C = 1.36944 rad =
A=78.463°
Answer:
37/50
Step-by-step explanation:
because 37% is out of 100
Answer: domain = 12 students
Range = $60
Step-by-step explanation:
Given that the total dollar amount earned, E. Is a function of the number of members who perform communityservice, n
That is
E(n) = 5n
Since the club earn $5 on each student who does community service,
Domain is independent variable n
While range is dependent variable E
Domain is therefore = 12 students
Range = 12 × 5 = $60
