In a science experiment, shelly has to weigh a compound in grams. the balance in her school measures in milligrams (mg). shelly finds that the weight of the compound is 8,450 mg. what is the value in grams (g) that shelly should enter? (grams : milligrams = 1 : 1,000)

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 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.

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
