Two boats depart from a port located at (–10, 0) in a coordinate system measured in kilometers, and they travel in a positive x-direction. the first boat follows a path that can be modeled by a quadratic function with a vertex at (0, 5), and the second boat follows a path that can be modeled by a linear function and passes through the point (10, 4). at what point, besides the common starting location of the port, do the paths of the two boats cross? (–6, 0.8) (–6, 3.2) (6, 3.2) (6, 0.8)

Consider an industrial process in the textile industry in which strips of a particular type of cloth are being produced. these strips are defective in two ways, length and nature of texture. for the case of the latter, the process of identification is very complicated. it is known from historical information on the process that 10% of the strips fail the length test, 5% fail the texture test and only 0.8% fail both tests. if a strip is selected randomly from the process, and a quick measurement identifies it as failing the length test, what is the probability that it is texture defective?
