24.2 for x ∈ [0, [infinity]), let fn(x) = x n . (a) find f(x) = lim fn(x). (b) determine whether fn → f uniformly on [0, 1]. (c) determine whether fn → f uniformly on [0, [infinity])

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

Find an equation of the line perpendicular to the graph.
