When a vertical beam of light passes through a transparent medium, the rate at which its intensity I decreases is proportional to I(t), where t represents the thickness of the medium (in feet). In clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity I of the incident beam. Find the constant of proportionality k, where k = In(4) 3 dt = KI. What is the intensity of the beam 17 feet below the surface? (Give your answer in terms of I. Round any constants or coefficients to five decimal places.)

Question
When a vertical beam of light passes through a transparent medium, the rate at which its intensity I decreases is proportional to I(t), where t represents the thickness of the medium (in feet). In clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity I of the incident beam. Find the constant of proportionality k, where dI dt k= In(4) 3 = KI. What is the intensity of the beam 17 feet below the surface? (Give your answer in terms of Io. Round any constants or coefficients to five decimal places.) 0.000761 X
