A satellite dish is being designed so that it can pick up radio waves coming from space. The satellite dish will be in the shape of a parabola and will be positioned above the ground such that its focus is 40 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, 20); y = one over eightyx2 + 20
(0, 10); y = one over one hundred twentyx2 + 10
(0, 20); y = one over eightyx2 − 20
(0, 10); y = one over one hundred twentyx2 − 10

In order to answer correctly, the list of possible answers must be re-written. Also, the second part of the question must be re-written. Surely the equation of the satellite dish is requested, not the equation for 'the satellite'.

Step-by-step explanation:

All parabolas have an equation of y = ax^2 + bx + c. None of the available answers is written with an up carrot (^) symbolizing a value of x squared, also written as x times x. Note that most computer keyboards have the up carrot symbol on the 6 key. You can depress both the shift key at the same time as the 6 key to get an up carrot. Blessings, A
