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 50 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, 25); y = one over one hundredx2 − 25

(0, 50); y = one over two hundredx2 − 50

(0, 25); y = one over one hundredx2 + 25

(0, 50); y = one over two hundredx2 + 50

(0, 25); y = one over one hundredx2 + 25

Step-by-step explanation:

Let the ground be at (0,0). The base should be located at the midpoint between the ground and the focus (0,50). The position of the base of the satellite is:

The base (vertex) is at (0, 25).

A parabola can be described by the following general formula:

Where h = 0, k = 25 and a =50 -25 =25.

The equation for the parabola is:

Therefore, the answer is:

(0, 25); y = one over one hundredx2 + 25

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

no he doesnt because "-16' is negatiive
