Answer:
D
Step-by-step explanation:
Solution:-
The standard sinusoidal waveform defined over the domain [ 0 , 2π ] is given as:
f ( x ) = sin ( w*x ± k ) ± b
Where,
w: The frequency of the cycle
k: The phase difference
b: The vertical shift of center line from origin
We are given that the function completes 2 cycles over the domain of [ 0 , 2π ]. The number of cycles of a sinusoidal wave is given by the frequency parameter ( w ).
We will plug in w = 2. No information is given regarding the phase difference ( k ) and the position of waveform from the origin. So we can set these parameters to zero. k = b = 0.
The resulting sinusoidal waveform can be expressed as:
f ( x ) = sin ( 2x ) ... Answer

24 • 24= 576 and 25 • 25= 625
76 • 76= 5,776 and 77 • 77= 5, 929
242 • 242= 58, 564 and 243 • 243= 59, 049√
766 • 766= 586, 756 and 767 • 767=588, 298
( by the way,
I'm squaring it because it's a square.)

3x -5≥ 5x-25
-3x. -3x
-----------------
---> -5 ≥2x -25
+25. +25
---------------------
---->20≥2x
20/2 ≥ 2x/2
----->10≥x, the greatest 'x' can be is 10.
5)x= 67° and y= 32°
(x-15)°=52°(vertically opposite angles)
=>x= 52+15° = 67°
Similarly, 4y= 128°(vertically opposite angles)
=>y=128/4= 32°
6) x= 5° , y= 22°
12x+15=75°(vertically opposite angles)
12x=75-15°
12x=60°
x= 5°
6y-27°=105°
6y= 105+27°
6y= 132°
y= 22°
Answer:
x = 0.72
Step-by-step explanation:
Given
3.8x = 2.736 ( divide both sides by 3.8 )
x = 0.72
