Q # 4.
The loudness of sound is based on intensity level measured in decibels using a logarithmic scale and is relative to (a ratio of) the weakest sound the ear can hear?
Research how sound is measured. Answer the following:
? The formula for measuring sound.
? Pick a specific sound, give the decibels of the sound, and explain what this measurement means.
Please be sure to cite all references using APA style
Q # 5.
Using the index of a sequence as the domain and the value of the sequence as the range, is a sequence a function?
Include the following in your answer:
? Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the arithmetic sequence?
? Which one of the basic functions (linear, quadratic, rational, or exponential) is related to the geometric sequence?
? Give at least two real-life examples of a sequences or series. One example should be arithmetic, and the second should be geometric. Explain how these examples would affect you personally.
