Question

HELLLLLLPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

no

Answer 2

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 A: Can this situation be represented by an exponential 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 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 by an exponential function? Justify your answer and write the appropriate function to represent this situation if 1000 lumens of light enter the cable. (4 points)

Answer 3

lol

Answer 4

man this is hell

Answer 5

@Hero @whpalmer4 @wwhitlock @wifibasedgod @Whitemonsterbunny17 @escapeshipshape @eifhbiew

Answer 6

okay um well its asking that can it be a exponential function

Answer 7

idk

Answer 8

thx @Hero

Answer 9

well it could be like this \[f(x)=1000(1.03)^{x}\]

Answer 10

sorry \[f(x) = 1000(0.2)^{}\]

Answer 11

\[^{x}\]

Answer 12

\[f(x) = 1000(0.2)^{x}\]

Answer 13

ok
@Hero i think i can because there is a principal and a average rate of change so yes right?

Answer 14

@Hero are you thar

Answer 15

@FlvsGirl @thomaster

Answer 16

@whpalmer4 @ganeshie8

Answer 17

The situation appears to be linear:
\(f(x) = 1000 - 1000(0.012)x\)

Answer 18

omg thx

Answer 19

there is another questions that i would need help

Answer 20

could you please help me

Answer 21

if i could give an amount of medals, it would be 20

Answer 22

All you have to do is just post your questions. If someone wants to help, they will help. In the mean time, while waiting, you can attempt the problem on your own. Taking initiative with attempting to solve your own problem helps. Asking good questions helps as well.

Answer 23

oh ok, i mean i already did i just want to see and double check :)

Answer 24

medal for @Hero literally a hero
