Determine if the given sequence is geometric. If the sequence is geometric, find the common ratio. 4, − 20 3, 100 9, − 500 27,... Is the sequence geometric? A. The sequence is geometric. The common ratio is. (Type an integer or a simplified fraction.)

B. The sequence is not geometric.

C. It cannot be determined whether the sequence is geometric or not.

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.
