Determine which of the four postulates, if any, can be used to prove that the triangles are congruent. 50 points

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).

Write an equation for the function that includes the points (1,4/5) and (2,2/3)

Find the zeros of each function. f(x) = x^2 + 5x - 6
