Question

Samara is adjusting a satellite because she finds it is not focusing the incoming radio waves perfectly. The shape of her satellite can be modeled by mc022-1.jpg where x and y are modeled in inches. She realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite?
(–3, –6)
(–3, –4)
(3, 6)
(6, 3)
pls hurry!

Answer 1

Answer:

the focus point of the satellite = (–3, –4)

Step-by-step explanation:

The shape of his satellite can be modeled by y^2+6y-3x+3=0

y² + 6y - 3x + 3 = 0

=> y² + 6y + 9 - 9  - 3x + 3 = 0

=> (y + 3)² -3x - 6 = 0

=> (y + 3)² = 3x + 6

=>  (y + 3)² = 3(x + 2)

=>  (y - (-3))² = 3(x - (-2))

=> 3(x - (-2)) = (y - (-3))²

h = - 2  , k = -3

Slightly Shifted

-3 & - 4

the focus point of the satellite = (–3, –4)
