The volume, Q, of a sound is inversely proportional to the square of the distance n, in meters, from the source of the sound. A sound is heard at 25 decibels at a distance of 100 meters from its source. Write a formula for Q as a function of n, including finding the value of any unknown constants.Find constants a, b, and c such that f(t) = at + bt + c is a quadratic function that has horizontal intercepts at t=-1, and t=2 and a graph containing the point (1,4).
