Determine how many terms of the following convergent series must be summed to be sure that the remainder is less than 10^{{-5}} Although you do not need? it, the exact value of the series is given. ln128=\sum_{k=1}^{\infty }\frac{7(-1)^{k+1}}{k}The number of terms that must be summed is \square .

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.
