60 + Years after “Brown v. Board" In 1954, the Supreme Court ended legal segregation in IJ. Spublic schools the bar graph shows the percentage of black and while U.S. adults ages 25 or older who completed high school since the end of segregation. The functions B ( x ) = 16 ln x + 23 and W ( x ) = 11 ln + 49 model the percentage of black adults. B ( x ), and white adults, W ( x ), who had completed high school x years after 1961. Use the appropriate model to determine the percentage of white adults who had completed high school in 2012. Round to the nearest percent. How well does this rounded value model the percents displayed by the graph? Use the appropriate model to determine when 90% of black adults will have completed high school. Round to the nearest year.
