Answer:
78 trees
Step-by-step explanation:

Side = 78 trees
Given:
Hyperbola
a=55,000 km and c=81,000 km
hyperbola is the origin and the
transverse axis is horizontal
Required:
Equation of the path of a
satellite
Solution:
Formula for hyperbola, (x-h)2/a2
– (x-k)2/b2 = 1
At origin, (h, k) = (0, 0)
(x-0)2/(55000)2 – (x-0)2/(81000)2
= 1

Answer:
Step-by-step explanation:
Your cousin wants to buy a coat and can spend at most $95. This means that the total amount of money that he can spend in buying the coat would be lesser than or equal to $95.
He has a coupon for $20 off any coat. Let x represent the cost of the coat. The amount that he can pay for the coat will be x - 20.
The inequality to find the original prices of coats he can afford would be
x - 20 lesser than or equal to 95
2.375 pounds. Just take 79.25 and subtract 76.875 and you get your results.
