Answer:
θ = 36.94°
Step-by-step explanation:
Brewster's law for polarization states that; tan(θ_p) = n2/n1
Where ;
θ_p is the polarizing angle
n1 is the index of refraction of first material
n2 is the index of refraction of second material
Now, our first material here is air while second material is water.
Index of refraction of water = 1.33 while index of refraction of air is 1
Thus,
tan(θ_p) = n2/n1 = 1.33/1
tan(θ_p) = 1.33
(θ_p) = tan^(-1)1.33
(θ_p) = 53.06°
Now, polarizing angle is the angle of incidence for which all the reflected light is polarized and it's above the vertical. Thus to get the angle to the horizontal, it will be;
θ = 90° - (θ_p) = 90° - 53.06° = 36.94°
When you use PEMDAS you end up with the answer of 12. 12 can’t be divided by 7 so 12^13-12^12 is not divisible by 7
You collected 80 cans while your friend collected 100<span />
A= adult /s=student
170/150= factor out the 10 out of each .you are left with 17 adult and 15 children .17/15
Step-by-step explanation:
2) Slope can be written as rise over run:
- rise: add to the y-value
- run: add to the x-value
3) Slope formula is: 
4) Average rate of change is the slope of the given interval:
a) when x = 0, y = 0 and when x = 1, y = -3
b) when x = -2, y = 0 and when x = -1, y = 3
c) when x = 0, y = 0 and when x = 2, y = 0
