Suppose that Keisha's blood pressure can be modeled by the following function:
\n" );
document.write( " \r
\n" );
document.write( "\n" );
document.write( "Keisha's blood pressure increases each time her heart beats, and it decreases as her heart rests in between beats. In this equation, p(t)is the blood pressure in mmHg (millimeters of mercury), and t is the time in minutes. \r
\n" );
document.write( "\n" );
document.write( "Find the following. If necessary round to the nearest hundredth.\r
\n" );
document.write( "\n" );
document.write( "Amplitude of p = 18
\n" );
document.write( "-------------------------------\r
\n" );
document.write( "\n" );
document.write( "Time for one full cycle of p:: (2pi)/(71pi) = (2/71) = 0.0281 seconds
\n" );
document.write( "Note: That doesn't sound right.
\n" );
document.write( "===============================\r
\n" );
document.write( "\n" );
document.write( "Number of heartbeats per minute:: 60/0.0281 = 2130
\n" );
document.write( "Note: That doesn't sound right. Normal heart beat rate is 70 per minute.
\n" );
document.write( "----

document.write( "Cheers,
