Jim's dog weighed 20 pounds as a 3 month old puppy. When it is fully grown it weights 100 pounds. What is the percent increase of the dogs weight?

What expression is equivalent to 1/2(2+3x-6)

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.

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12
