Question

Fiber-optic cables are used widely by broadcast and cable companies. When light passes through a fiber-optic cable, its intensity decreases with the increase in the length of the cable. If 1000 lumens of light enters the cable, the intensity of light decreases by 1.2% per meter of the cable.
Part B: Write a function f(x) to represent the intensity of light, in lumens, when it has passed through x meters of the cable.
Part C: Some scientists are trying to make a cable for which the intensity of light would decrease by 8 lumens per unit length of the cable. Can this situation be represented b

Answer 26

1.2% is 0.012

if you start with 1, and go 1 meter, you will have 0.988
if you go 2 meters, you will have 0.988*0.988 = 0.988^2

is that enough of a hint?

ok hmm
