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

pychu [463]

Answer:

the base of the satellite should be positioned at (0,20)

the best model which describes the equation of the satellite is $\mathbf{y = \dfrac{x^2}{80} + 20}$

Explanation:

From the information given:

A satellite dish is designed in such a way that it can pick up radio waves coming from the space.

This satellite dish is designed in the shape of a parabola.

Location of the satellite is situated above the ground

Focus of the satellite is 40 ft above the ground

Using the ground as the x - axis

The objective here is to determine where should the base of the satellite be positioned? &

Which equation best describes the equation of the satellite?

Using the ground as the x - axis;

Let say the x- axis start from the origin (0,0)

Then;

The Focus of the satellite which is 40 ft above the ground will be (0,40)

The position of the base of the satellite will be the vertex (h,k) which is at an equidistant position between the ground and the focus.

(h,k) = (0,20)

The model which best describes the equation of the satellite is as follows :

$(x - h)^2 = 4a(y - k) \\ \\ where ; \\ \\ (h,k) = (0,20) , \\ a = 20(x - 0)^2 = 4(20)(y - 20)\\ \\x^2 = 80( y - 20)\\ \\x^2= 80y - 1600\\ \\y = \dfrac{x^2}{80} + 20$

If a molecule demonstrates paramagnetism, then : I. The substance can have both paired and unpaired electrons. II. The bond orde

jolli1 [7]

Answer:The bond order is not a whole number.

Explanation:

If a molecule is paramagnetic, then there are unpaired electrons in some of its molecular orbitals. This will cause the bond order not to be a whole number when treated by applying the ordinary molecular orbital theory to the molecule.
