A baseball hit from home plate is described by the equation \n" ); document.write( " h = -16t^2 + 100t + 5, where the height is h and the time is t. \n" ); document.write( "The bleachers are 20 feet from the ground. \n" ); document.write( " When will the baseball land in the bleachers? \n" ); document.write( " Round your answer to the nearest tenth of a second. \n" ); document.write( ": \n" ); document.write( "The equation for this scenario; h = 20, therefore \n" ); document.write( "-16t^2 + 100t + 5 = 20 \n" ); document.write( "-16t^2 + 100t + 5 - 20 = 0 \n" ); document.write( "-16t^2 + 100t - 15 = 0 \n" ); document.write( "Use the quadratic formula \n" ); document.write( " \n" ); document.write( "In this equation x=t; a=-16; b=100; c=-15 \n" ); document.write( " \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( "You should be able to do the math now, only one solution will make sense \n" ); document.write( " |
