Work: Calculate the value of equation 0.28*35*(6.6+1.91)+0.5*0.28*18*(6.6+1.91)^2-1/2*5*18*1.91^2 .
Question type: Mathematical calculation
Solution:
0.28*35*(6.6+1.91)+0.5*0.28*18*(6.6+1.91)^2-1/2*5*18*1.91^2
=0.28*35*8.51+0.5*0.28*18*(6.6+1.91)^2-1/2*5*18*1.91^2
=0.28*35*8.51+0.5*0.28*18*8.51^2-1/2*5*18*1.91^2
=0.28*35*8.51+0.5*0.28*18*72.420099999999991-1/2*5*18*1.91^2
=0.28*35*8.51+0.5*0.28*18*72.420099999999991-1/2*5*18*3.6481
=9.8*8.51+0.5*0.28*18*72.420099999999991-1/2*5*18*3.6481
=83.398+0.5*0.28*18*72.420099999999991-1/2*5*18*3.6481
=83.398+0.14*18*72.420099999999991-1/2*5*18*3.6481
=83.398+2.52*72.420099999999991-1/2*5*18*3.6481
=83.398+182.498652-1/2*5*18*3.6481
=83.398+182.498652-0.5*5*18*3.6481
=83.398+182.498652-2.5*18*3.6481
=83.398+182.498652-45*3.6481
=83.398+182.498652-164.1645
=265.896652-164.1645
=101.732152
Answer:0.28*35*(6.6+1.91)+0.5*0.28*18*(6.6+1.91)^2-1/2*5*18*1.91^2=101.732152
