MEDAL! I need help with writing functions/formulas when given information:
If a science team uses a remote controlled submarine to measure the intensity of sunlight at various depths of the ocean, and the percent of intensity of surface sunlight is 44.5% at 3.3 feet and reduces to around 5.7% at 9.3 feet, which of the equations given reveals the growth rate of the intensity of surface sunlight at a depth of d feet from 3.3 feet onwards?
A) y = 44.5(1 + 0.29)^d
B) y = 44.5(1 - 0.29)^d
C) y = 44.5(100/94.3)^-d
D) y = 44.5(1 - 0.057)^1/d
THANK YOU!!
