Find the equation that models the path of a satellite if its path is a hyperbola, a=55,000 km and c=81,000 km. Assume the center
Yuki888 [10]

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

What is y+1=2(x-4) written in standard form
IrinaVladis [17]

Answer:

2x - y = 9

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Rearrange y + 1 = 2(x - 4) into this form

y + 1 = 2x - 8 ( add 8 to both sides )

y + 9 = 2x ( subtract y from both sides )

9 = 2x - y ⇒ 2x - y = 9 ← in standard form
