Jeff is a bird watcher. Every year in the first week of spring, he visits the Hawk Mountain Sanctuary in Pennsylvania. Last year, he saw 12 Turkish vultures, 2 bald eagles, 4 northern goshawks, and 7 red-tailed hawks. Jeff didn’t see any other birds. This year, the sanctuary authorities are expecting 175 birds during the time he visits. Use this data to predict the count of each bird that will be in the sanctuary during this year’s visit.

the loudness in decibels of sound is defined as 10 log I/I0, where I is the intensity of the sound in watts per square meter (W/m2). I0, the intensity of a barely audible sound, is equal to 10 -12 W/m2. town regulations require the loudness of construction work not to exceed 100 dB. suppose a construction team is blasting rock for a roadway. one explosion has an intensity of 1.65 X 10-2 W/m2. is the explosion in violation of town regulations? which physical value do you need to calculate to answer the question? what values should you use for I and I0
