A sea turtle population is modeled by the equation where is the number of years since the population was first measured.

How many turtles are in the population when it is first measured? Where do you see this in the equation?
Is the population increasing or decreasing? How can you tell from the equation?
When will the turtle population reach 700? Explain how you know.

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
