document.write( "Question 311949: distance traveled by an object moving in a straight line is given by s = t^2 + 8t, where s is in ft. and t is the time in seconds has been in motion. How long (to the nearest tenth) will it take the object to move 9 ft. Please show your work, i am having a really hard time getting this! \n" ); document.write( "

$\"s+=+t%5E2+%2B+8t\"$
\n" ); document.write( " $\"s+=+9\"$ ft
\n" ); document.write( " $\"9+=+t%5E2+%2B+8t\"$
\n" ); document.write( " $\"t%5E2+%2B+8t+-+9+=+0\"$
\n" ); document.write( " $\"%28t+-+1%29%28t+%2B+9%29+=+0\"$
\n" ); document.write( " $\"t+=+1\"$ (can't use negative answer)
\n" ); document.write( "It will take 1 sec for the object to move 9 ft \n" ); document.write( "

\n" );
