Deanna 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 x^2=12y 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?

The shape of satellite which is in the shape of parabola, opening upwards is, , having vertex (0,0).

Comparing with general equation of parabola

, having vertex (0,0) and focus (0,a).

Comparing the two above equation of parabola

4 a y = 12 y

4 a = 12

a=3

So, focus of the satellite which is in the shape of parabola=(0,3)

he sells x mount because thats eqivilqant to the maz and then divided into quarters

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
