You can put this solution on YOUR website!
The height y (in feet) of a ball thrown by a child is
\n" ); document.write( "y=−16x^2+2x+5
\n" ); document.write( "==============
\n" ); document.write( "That's the height as a function of the time in seconds.
\n" ); document.write( "===============
\n" ); document.write( "I doubt you entered the problem correctly.
\n" ); document.write( "=================================\r
\n" ); document.write( "\n" ); document.write( " where x is the horizontal distance in feet from the point at which the ball is thrown.\r
\n" ); document.write( "\n" ); document.write( " (a) How high is the ball when it leaves the child's hand? ________ feet
\n" ); document.write( "5 feet
\n" ); document.write( "=======================
\n" ); document.write( " (b) What is the maximum height of the ball? _______feet\r
\n" ); document.write( "\n" ); document.write( " (c) How far from the child does the ball strike the ground? ________feet\r
\n" ); document.write( "\n" ); document.write( "=================
\n" ); document.write( "The \"________ feet\" serves no purpose and is irritating. Why do you think we need that?
