The loudness of a sound, d, in decibels, is given by the formula d = 10log(10^12 i) where i is the intensity of the sound, in watts per meter square. the sound of a blue whale can be heard 500 miles away, reaching an intensity of 6.3 x 10^6 watts per meter square. determine the decibel level of this sound.

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
