The satellite dish will be in the shape of a parabola and will be positioned above the ground such that its focus is 30 ft above the ground. Using the ground as the x-axis, where should the base of the satellite be positioned? Which equation best describes the equation of the satellite?

(0, 60); y = one over two hundred fortyx2 + 60

AfilCa [17]

Answer:

  8,275,842 digits

Expressed in the base-37 number system, P has 8275842 digits.

Good morning☕️

______

Answer:

w is the width

L is the length

p is the perimeter

L=27

___________________

Step-by-step explanation:

p=2[(L-4) + (w+1)]

⇔p=2[(3w-4) + (w+1)]

⇔p=2[4w-3]

⇔p=8w-6

⇔66=8w-6

⇔8w=72

⇔w=9

Then L=3w=27
