Answer:

Step-by-step explanation:
the transverse axis is horizontal.
so its a horizontal hyperbola
Center is the origin so center is (0,0)
Equation of horizontal hyperbola is

Given a= 55000 and c= 81000
c^2 = a^2 + b^2
81000^2 = 55000^2 + b^2
subtract 55000^2 on both sides
b = sqrt(81000^2 - 55000^2)= 59464.27
now plug in the values

Answer:
Lateral surface area is the round part/the middle part of the cylinder, not the bases
Step-by-step explanation:
50% of 40 is 20, and 40% of 50 is 20, neither one is greater, they're equal
Answer:
Step-by-step explanation:
-9/10 or -0.9
9x135 = 1,215
10x135 = 1,350
11x135 = 1,485
Therefore, your answer would be 10.
