#3.......the 3 with the m makes it greater than 1
Answer:
The angles are related by Snell's Law of refraction.
Step-by-step explanation:
When light is incident on a medium at an angle this angle is known as angle of incidence and it undergoes refraction in the medium at an angle meaning that it deviates from it's normal path this angle of deviation measured with respect to normal is known as angle of refraction and are related by Snell's Law as under
here 
is the refractive index of material of lens and 
is the refractive index of air equaling 1
Answer:
Hello there the Correct answer The only answer choice that produces -2x²+2 is D.
Because (-x²+2x+3)+(-x²-2x-1) = -x²+2x+3-x²-2x-1 = -2x²+2
answer: D
Hope It Helps!
Answer:
c: 1,335 yd³
Step-by-step explanation:
The formula for volume of a cylinder is V = πr²h where r is the radius of the base circle, and h is the height of the cylinder
We are given r = 5, and h = 17. Plug them in and solve for V...
V = π(5²)(17)
V = π(25)(17)
V = 425π
V = 425(3.14) = 1,334.5 yd³,
so 1,335 yd³ rounded to the nearest cubic yard
