Triangle LMN has side lengths of 18.5 inches, 10 inches, and 15.5 inches. Use the Converse of the Pythagorean Theorem to prove that triangle LMN is not a right triangle.

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

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. y = 9 + 12x + 4x^2
