Answer:
Enlargement Areas
Step-by-step explanation:
if you enlarge the little one, they will intersect each other perfectly because those triangles are similar and the same. they are just different sizes
hope this helps!
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°
Answer:
8x^2(x^2-8)
Step-by-step explanation:
you find the lCM
the LCM of 16 and 8 is 8
the LCM of x^2 and x^4 is x^2
in all the LCM is 8x^2
8x^4/8x^2=x^2
you divide the numbers and subtract the powers of the variables
<h3>-16x^2/8x^2= -8 </h3><h3>the you put everything in a distribution form</h3><h3 />
Answer:
D year 15
Step-by-step explanation:
Given:
y= 8x^2-40x+6
year is the best prediction for when 1206
Finding value of x for y=1206
8x^2-40x+6= 1206
8x^2-40x+6-1206=0
8x^2-40x-1200=0
Solving the above by quadratic formula:
x= 
= 
x= 15 and x= -10
As year can not be negative, hence correct answer is
D: year 15!
