A satellite dish is shaped like a paraboloid of revolution. The signals that emanate from a satellite strike the surface of the
allochka39001 [22]

Answer:

The receiver must be placed at a distance of 6.125 ft from the center.

Step-by-step explanation:

The dish is of parabola shape with the length of 14 feet and 2 feet deep from the center.

A parabola is a curve which is a set of all points in the plane which are at equal distance away from a given point called focus and given line called directrix.

We have to find out the point at which all the waves comes to one point where the receiver must be placed is the focus of the parabola.

The above scenario is shown in the image which can be converted in mathematical graphical representation of the parabolic curve.

The extreme two end points becomes, (-7,2) and (7,2)

The general equation for such parabola is:

x² = 4ay

where, a is the distance from the center and the focus.

Since, (7,2) satisfy the equation so,

7² = 4a×2

a = 49 /8

Thus,

<u>The receiver must be placed at a distance of 6.125 ft from the center.</u>

Which inequality represents all values of x for which the quotient below is<br> defined?
garri49 [273]

Answer:

Option B: x > 0

Step-by-step explanation:

Option A is wrong because \sqrt{3(0)}will be 0. So, the inequality can't be divided by 0.

Option C is wrong because 1 will suffice this inequality. \sqrt{7}/\sqrt{3}=1.5 (approx)

Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).

Leaving us with only option B, which is the right answer.
