Solve the problem.Ultraviolet solar radiation (UV) is strongly absorbed by ocean water. The intensity of the UV at a particular depth can be calculated using the equation I = I0e-0.3d, where d is the depth in centimeters (cm), I0 is the intensity at the surface, and I is the intensity at depth d. Find the depth at which the intensity is 15% of its value at the surface. Round to the nearest tenth when necessary.
