Answer:

x= 1 or x=7

Step-by-step explanation:

2 x 2− 16 x + 14 =0

Find an 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 cen

Answer:

$\frac{x^2}{55000^2} - \frac{y^2}{59464^2} =1$

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

$\frac{x^2}{a^2} - \frac{y^2}{b^2} =1$

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

$\frac{x^2}{55000^2} - \frac{y^2}{59464^2} =1$

A cell phone company charges a monthly fee of $35 and an addition $0.20 per minute used.

kiruha [24]

Answer:

35 + .2m

Step-by-step explanation:

The monthly fee of $35 is a base pay, and you don't change anything with it.

The "m" stands for minute, and since it costs $.20 for each minute, multiply the two together to get that part of the equation.
