(a) △abc with a=10, b=24, c=26 (b) △def with d=13, e=85, f=84 (c) △ghi with g=40, h=10, i=41 (d) △pqr with p=18.5, q=6, r=17.5 (e) △stu with s=√11, t=7, u=√38 (f) △wxy with w=5, x=√40, y=8 √ is square root.

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.

The graph of a function f(x)=(x+2)(x-4). which describes all of the values for which the graph is negative and increasing? all real values of x where x< -2 all real values of x where -2
