If the coefficient ranges from -1.00 to 1.00, what is the strongest negative relationship? A)- 10
B) 1.00
C) - 99
D) -1.00

c) It can be equal to 1.00 but it can also be greater than 1.00. It is never less than 1.00.

Explanation:

Refractive index is equal to velocity of the light 'c' in empty space divided by the velocity 'v' in the substance.

Or ,

n = c/v.

Since speed of the light 'v' in any medium is always be less than or equal to speed of the light in the vacuum 'c', thus, the index of refraction is always be greater than or equal to 1.0.

Step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
