a ball is dropped from a height of 30 feet.each time it strikes the ground, it bounces up to 4/5 of the previous height. how many times does the ball hit the ground before it bounces up less than 6 feet?
\n" ); document.write( "
This situation depicts a sequence with \"a%5B1%5D\" being 30, r being \"4%2F5\", and \"a%5Bn%5D\" being 5 (< 6). 
\n" );
document.write( "We then have: \"a%5Bn%5D+=+a%5B1%5Dr%5En\" 
\n" );
document.write( "\"5+=+30%284%2F5%29%5En\" 
\n" );
document.write( "\"5%2F30+=+%284%2F5%29%5En\"_____\"1%2F6+=+%284%2F5%29%5En\"
\n" );
document.write( "\"log+%284%2F5%2C+%281%2F6%29%29+=+n\"
\n" );
document.write( "\"log+%281%2F6%29%2Flog%284%2F5%29+=+n\"
\n" );
document.write( "n, or number of bounces = 8.029626932, or \"highlight_green%28n+=+8%29\" \n" );
document.write( "
\n" );
