Question

Fiber-optic cables are used widely to increase the speed and accuracy of data transmission. When light passes through a fiber-optic cable, its intensity decreases with the increase in the length of the cable. If 1700 lumens of light enters the cable, the intensity of light decreases by 1.9% per meter of the cable.

Part A: Can this situation be represented by a linear function? Justify your answer. (2 points)

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. (4 points)

Part C: Some scientists are trying to ma

Answer 2

its intensity decreases with the increase in the length of the cable
let s = intensity and l = length then sl = k inverse relation

Answer 3

If 1700 lumens of light enters the cable, the intensity of light decreases by 1.9% per meter of the cable.
1700 =1 -1.9 % L
