Work: Calculate the value of equation (2.1-0.433)*(-0.28-0.0933)+(0.2-0.433)*(0.08-0.0933)+(-1-0.433)*(0.48-0.0933) .
Question type: Mathematical calculation
Solution:
(2.1-0.433)*(-0.28-0.0933)+(0.2-0.433)*(0.08-0.0933)+(-1-0.433)*(0.48-0.0933)
=1.667*(-0.28-0.0933)+(0.2-0.433)*(0.08-0.0933)+(-1-0.433)*(0.48-0.0933)
=1.667*(-0.3733)+(0.2-0.433)*(0.08-0.0933)+(-1-0.433)*(0.48-0.0933)
=1.667*(-0.3733)+(-0.233)*(0.08-0.0933)+(-1-0.433)*(0.48-0.0933)
=1.667*(-0.3733)+(-0.233)*(-0.0133)+(-1-0.433)*(0.48-0.0933)
=1.667*(-0.3733)+(-0.233)*(-0.0133)+(-1.433)*(0.48-0.0933)
=1.667*(-0.3733)+(-0.233)*(-0.0133)+(-1.433)*0.3867
=-0.622291+(-0.233)*(-0.0133)+(-1.433)*0.3867
=-0.622291+0.003099+(-1.433)*0.3867
=-0.622291+0.003099+(-0.554141)
=-0.619192+(-0.554141)
=-1.173333
Answer:(2.1-0.433)*(-0.28-0.0933)+(0.2-0.433)*(0.08-0.0933)+(-1-0.433)*(0.48-0.0933)=-1.173333
