\"The equation $\"y=-16t%5E2%2B26t%2B105\"$ describes the height (in feet) of a ball tossed up in the air at 26 feet per second from a height of 105 feet above the ground.
\n" ); document.write( " In how many seconds will the ball hit the ground? Express your answer as a decimal rounded to the nearest tenth.\"
\n" ); document.write( ":
\n" ); document.write( "When it hits the ground y=0, therefore:
\n" ); document.write( " $\"-16t%5E2%2B26t%2B105+=+0\"$
\n" ); document.write( "Use the quadratic formula; a=-16; b=26; c=105
\n" ); document.write( "I got a positive solution: t=3.5 seconds \n" ); document.write( "

\n" );
