Do you tailgate the car in front of you? about 40% of all drivers will tailgate before passing, thinking they can make the car in front of them go faster. suppose that you are driving a considerable distance on a two-lane highway and are passed by 6 vehicles. (a) let r be the number of vehicles that tailgate before passing. make a histogram showing the probability distribution of r for r = 0 through r = 6

Solve the system of equations. y= 2x y= x^2 - 15

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

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.
