Answer:

  √3/11, π/24, 3/25, 9/100

Step-by-step explanation:

The 2-decimal value of each of the numbers is ...

  9/100 = 0.09

  π/24 = 0.13

  3/25 = 0.12

  √3/11 = 0.16

Then the order from greatest to least is 0.16, 0.13, 0.12, 0.09. In the original form, that is ...

  √3/11, π/24, 3/25, 9/100 . . . . . matches choice B

A satellite dish is shaped like a paraboloid of revolution. The signals that emanate from a satellite strike the surface of the
antiseptic1488 [7]

Answer:

c = 9 feet

Step-by-step explanation:

In this situation, one is to find the 'c' : that is, the distance between the vertex and the focus.

Given that, the equation for a vertical parabola:

y = (1/4c)(x-h)^2 + k

Supposing we place our parabola at the center, our equation becomes:

y = (1/4c)x^2

.

The problem gives us a point on the parabola: (12,4)

Then insert it in and solve for 'c':

y = (1/4c)x^2

4 = (1/4c)12^2

4 = (1/4c)144

4 = (1/c)36

4c = 36

c = 36/4

c = 9 feet
