4/3+6/9-7/3=12/9+6/9-21/9=18/9-21/9= -3/9= -1/3
Answer:
y=x+4
Step-by-step explanation:
2y=2x+4 simplifies down to y=x-2. Since the two lines are parallel, they have to have the same slope, but different y-intercepts. This means that we just have to find the y-intercept that will allow our line to pass through (-5, -1).
If we input the coordinates into what of our equation we have thus far (y=x+b), we just have to find what b needs to equal to make the equation true.
-1=-5+b -1=-5+4
b = 4 -1=-1

Equation of line in slope intercept form


Answer:
θ
- θ
Step-by-step explanation:
According to the theory of Malus, when a completely plane polarized light is incident on an analyzer, the intensity 'I' of the light wave transmitted by the analyzer is proportional to the square of the cosine of angle between the transmission axes of the polarizer and analyzer. Therefore:
Using the theory of Malus, we need to estimate the angle between the transmission axis θ
and the polarization axis θ
.
Thus:
angle θ = θ
