Answer:
![y=[1]cos([\frac{2\pi }{3}]x)](https://tex.z-dn.net/?f=y%3D%5B1%5Dcos%28%5B%5Cfrac%7B2%5Cpi%20%7D%7B3%7D%5Dx%29)
Step-by-step explanation:
Looking at the graph, we can see the domain to be from (0 , 2π).
Now we have to find one period that corresponds to cos(x).
The half-period of cos(x) for this graph appears to be pi/3 and adding another pi/3 gets us 2pi/3 to be our cosine period.
b = 2pi/3
a is the same range as cos(x). Range: (0,0)
y = [a] * cos ([b]*x)
y = [1] * cos([2pi/3]x)
Answer:KW=160
Step-by-step explanation:
m∠A=1/2(KW)
Sub: x+45=1/2(x+20+3x)
x=35
KW=x+20+3x
KW=35+20+3(35)
KW=160

Answer:
Step-by-step explanation:
Well with what
X=-4
Y=4
The horizontal (left to right) line represents the x-axis!
The vertical (up and down) line represents the y-axis!
