Look at the turning point and put the co-ordinated into completed square form then break the brackets .

Example : say the turning point was (4 , 11)

Completed square form : (x +2) ^2 +7

Break the brackets and factorise

X^2 + 4x + 7





Sorry if its wrong

</span></span>Parabolic antenna is a device Digital FTA TV and Radio broadcast receivers that transmit it via satellite as free to air, with this device, the TV signal reception is not affected anymore by the surrounding environment such as trees, mountains and so forth.



Other advantages that we can enjoy with one of these digital devices is the quality of the resulting images and sound, no matter how good the picture and sound produced by analog antenna (antenna UHF and VHF) still can not collate the quality of picture and sound Digital Antenna Parabola. Even now there are parabolic antenna device capable of receiving broadcast digital HDTV (high-definition television)

Her general FTA Digital Satellite dish antenna consists of four main parts:
1. SOLID DISH Parabola
2. LNB (Low Noise Block Converter).
3. DiSCq (Digital Satellite Equipment Control).
4. Receiver DVB (Digital Video Broadcasting) FTA (Free To Air).</span>

Enter the range of values for x:<br> B<br> 15<br> 2x - 10<br> С<br> 48°<br> A<br> 18<br> [?] Enter
SOVA2 [1]
<h3>Answer:   5 < x < 29</h3>

=========================================

Explanation:

Since AB is smaller than AD, this must mean the angle ACB is smaller than angle ACD. Note how these angles are opposite the sides mentioned.

So 2x-10 < 48

At the same time, 2x-10 is also larger than 0.

Overall, we can say 0 < 2x-10 < 48

---------

Let's solve for x

0 < 2x-10 < 48

0+10 < 2x < 48+10 ...... add 10 to all sides

10 < 2x < 58

10/2 < x < 58/2 ..... divide all sides by 2

5 < x < 29

Evaluate g(x) = x2 + 5 given the inputs (-1,0,1,2}
mihalych1998 [28]

Answer:

g(-1) = 6

g(0) = 5

g(1) = 6

g(2) = 9

Step-by-step explanation:

Step 1: Plug in -1 for <em>x</em>

g(-1) = (-1)² + 5

g(-1) = 1 + 5

g(-1) = 6

Step 2: Plug in 0 for <em>x</em>

g(0) = 0² + 5

g(0) = 0 + 5

g(0) = 5

Step 3: Plug in 1 for <em>x</em>

g(1) = 1² + 5

g(1) = 1 + 5

g(1) = 6

Step 4: Plug in 2 for <em>x</em>

g(2) = 2² + 5

g(2) = 4 + 5

g(2) = 9

Tysm for the help! &lt;3

By using the given graph:

  • When x = -2, the value of the function is f(-2) = 1
  • When x = -0.5, the value of the function is f(-0.5) = 0.75
  • When x = 0, the value of the function is f(0) = 1.25
  • When x = 2.5, the value of the function is f(2.5) = 3
  • When x = 6, the value of the function is f(6) = 0
<h3></h3><h3>How to use the graph to find the values of the function?</h3>

Suppose that we want to find the value of the graphed function when x = a.

  • Then we first need to identify x = a in the horizontal axis.
  • Then we move upwards (or downwards) until we meet the curve of the function.
  • Now you can move horizontally towards the vertical axis, where you can read the y-value associated to the x-value.

Now we can do these steps for each of the wanted values.

  • When x = -2, the value of the function is f(-2) = 1
  • When x = -0.5, the value of the function is f(-0.5) = 0.75
  • When x = 0, the value of the function is f(0) = 1.25
  • When x = 2.5, the value of the function is f(2.5) = 3
  • When x = 6, the value of the function is f(6) = 0
