Question

help please will fan and metal

Answer 1

Fiber-optic cables are used widely for internet wiring, data transmission, and surgeries. When light passes through a fiber-optic cable, its intensity decreases with the increase in the length of the cable. If 1500 lumens of light enters the cable, the intensity of light decreases by 3.4% 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 make a cable for which the intensity of light would decrease by 5 lumens per unit length of the cable. Can this situation be represented by a linear function? Justify your answer and write the appropriate function to represent this situation if 1500 lumens of light enter the cable. (4 points)

Answer 9

If \(\Large\rm x\) is our meters that we've traveled,
and we're losing \(\Large\rm 5\) lumens each meter,
then we're losing \(\Large\rm 5\) lumens each \(\Large\rm x\).
Written as: \(\Large\rm 5x\)

And we start out with \(\Large\rm 1500\) lumens of light,
After we've traveled \(\Large\rm x\) meters,
we're left with \(\Large\rm 1500-5x\).
