Answer:
Solution : y = ± 1/3x
Step-by-step explanation:
Remember that the equation of a hyperbola is in the form (y - k)² / a² - (x - h)² / b² = 1. Therefore we have a² here = 9, and b² here = 81.
To determine the asymptotes we can use the equation y = k ± a/b(x - h). What makes this equation really simple, is that k = 0 and h = 0, giving us y = ± a/b(x). Let's isolate a and b given a² = 9, and b² = 81 --- (1)
a² = 9
a = 3
b² = 81
b = 9
Therefore our asymptotes will be in the form y = ± a/b(x) = ± 3/9(x) = ± 1/3x. Our solution is thus option a.
Answer:
B
Step-by-step explanation:
I think its B dont quote me
Flip the second fraction and change the fraction into multiplication
Also, change 2 1/2 into a improper fraction
2 1/2 = 5/2
(5/2)/(5/8) becomes 5/2 x 8/5
Multiply across
5 x 8 = 40
------- -----
2 x 5 = 10
Simplify 40/10
40/10 = 4
4 is your answer
hope this helps
