Algebra.Com's Answer #516435 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The point P is on the unit circle. Find P(x,y) from the given information. The x coordinate of P is 4/5 and P is in Quadrant I. \n" ); document.write( "------- \n" ); document.write( "Since the point is on the circumference of a unit circle, \n" ); document.write( "x^2 + y^2 = 1 \n" ); document.write( "--------------------------- \n" ); document.write( "Your point is ((4/5),y) and y is positive \n" ); document.write( "(4/5)^2 + y^2 = 1 \n" ); document.write( "y^2 = (25/25)-(16/25) \n" ); document.write( "y^2 = 9/25 \n" ); document.write( "y = 3/5 \n" ); document.write( "------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "=================== \n" ); document.write( " |
