Work: Calculate the value of equation (4/7)^2*0.15^2+(3/7)^2*0.04+2*4/7*3/7*(-0.03) .
Question type: Mathematical calculation
Solution:
(4/7)^2*0.15^2+(3/7)^2*0.04+2*4/7*3/7*(-0.03)
=0.571429^2*0.15^2+(3/7)^2*0.04+2*4/7*3/7*(-0.03)
=0.571429^2*0.15^2+0.428571^2*0.04+2*4/7*3/7*(-0.03)
=0.571429^2*0.15^2+0.428571^2*0.04+2*4/7*3/7*(-0.03)
=0.326531102041*0.15^2+0.428571^2*0.04+2*4/7*3/7*(-0.03)
=0.326531102041*0.0225+0.428571^2*0.04+2*4/7*3/7*(-0.03)
=0.326531102041*0.0225+0.183673102041*0.04+2*4/7*3/7*(-0.03)
=0.007347+0.183673102041*0.04+2*4/7*3/7*(-0.03)
=0.007347+0.007347+2*4/7*3/7*(-0.03)
=0.007347+0.007347+8/7*3/7*(-0.03)
=0.007347+0.007347+1.142857*3/7*(-0.03)
=0.007347+0.007347+3.428571/7*(-0.03)
=0.007347+0.007347+0.489796*(-0.03)
=0.007347+0.007347+(-0.014694)
=0.014694+(-0.014694)
=0
Answer:(4/7)^2*0.15^2+(3/7)^2*0.04+2*4/7*3/7*(-0.03)=0
