Evaluate the expression for the given variable values.

3∣m+2n∣2−(mn)2 if m=3 and n=−5

Which of the following is the correct ratio for converting kilograms to grams

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
