The graph of a quadratic function intercepts the x-axis in the two places and the y-axis in one place. according to the fundamental theorem of algebra, which of the following statements is correct? 1 the quadratic function has no real zeros and two non-real zeros. 2 the quadratic function has two distinct real zeros and one distinct non-real zero. 3 the quadratic function has two distinct real zeros. 4 the quadratic function has one distinct real zero and one distinct non-real zero.

Quadrilateral abcd in the figure below represents a scaled-down model of a walkway around a historic site. quadrilateral efgh represents the actual walkway. abcd is similar to efgh. what is the total length, in feet of the actual walkway?

Choose the linear inequality that describes the graph. the gray area represents the shaded region. a: y ≤ –4x – 2 b: y > –4x – 2 c: y ≥ –4x – 2 d: y < 4x – 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.
