The loudest animal on Earth is the blue whale. Blue whales can emit sound with an intensity of 106.8 watts/meter. The equation
B = 10 log() relates the sound level, B, in decibels (dB), of a nolse with an intensity of I to the smallest sound intensity that can be heard
by the human ear, 10 (approximately 1 x 10–12 watts/meter?).
Based on this information, which value is closest to the sound level, in decibels, of the vocalizations of a blue whale?
OA.
240 dB
OB.
1,000 dB
Ос.
140 dB
OD
100 dB

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
