Answer:
All you have to do is find out the answer on your own buddy.
Step-by-step explanation:
ANSWER:
f(x)⁻¹ = (x+10)/2
WORKING OUT:
f(x) = 2x - 10
y = 2x - 10
*Replace all 'y' values with 'x' and vice versa*
x = 2y - 10
*Make y the subject of the equation*
2y = x+10
y = (x+10)/2
There is a reflection at the boundary between two materials if there is a change of<u> the speed of light in the material </u>at the boundary.
This bending is referred to as refraction. whilst a wave traveling at an angle adjusts its velocity upon crossing a boundary among materials,. This bending is known as refraction. As a wave crosses a boundary into a new medium, its pace, and wavelength exchange simultaneously as its frequency stays equal.
While light from air hits a smooth piece of glass (n = 1. five) with the ray perpendicular to the glass floor, of the subsequent will occur while light from air hits a clean piece of glass with the ray perpendicular to the glass surface, the part of the light passing into the glass: will now not exchange its frequency.

i believe your answer will be 0.04 or 4/100
OR if you need an equivalent expression, that would be 81/2187
Yoy multiply 55 and 99 and get 5000 and than you times it an get your answer
