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

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).

1.2million users of social media via mobile devices were added each day. How many users added on an average each second

Pachacha [2.7K]

Answer: 14 new users are added per second

Step-by-step explanation:

1,200,000/24 = 50000

50000/60 = 833.333333333

833.333333333/60 = 13.8888888889

then round because it said on average

so if we round 13.8888888889 we get 14

so on average 14 new users are added per second.

Each interior angle of the regular n-gon has a measure of 140

xeze [42]

Sum of internal angles of any polygon is: (n-2)x180
So measure of an interior edge is ( ( n - 2 ) x 180 ) / n = 140
So 140n = 180n - 360
40n = 360
n = 9
So it's a nonagon.

Hope this helps :)
