(M'T') has coordinates M'(-1,3) and T'(12,-6), and it is the result of the dilation of (MT) centered at the origin. The coordinates of (MT) are M(-1/3,1) and T(4,-2). Complete the following algebraic description so that it represents the transformation of (MT)

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).
