The diameter of a circle has endpoints p(–10,–2) and q(4,6). a. find the center of the circle. b. find the radius. if your answer is not an integer, express it in radical form. c. write an equation for the circle. you see, the thing is, i think i have the center of the circle (a), which is (-3,2). but i don't know what to do about b or ?

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.
