The chance of getting into a car accident increases exponentially if the driver has consumed alcohol. The relationship can be modeled by A(c) = 6e^12.8c, where A is the % chance of an accident and c is the driver’s blood alcohol concentration (BAC). The legal BAC is 0.08. What is the percent chance of having a car accident at this concentration? What BAC would correspond to a 50% chance of having a car accident?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
