Xo‘jalik faoliyati tahlili: moliyaviy tahlil (ichki va tashqi); boshqaruv tahlili

U = x*y*z
∆U_x = 1/2∆x*(y₁*z₀ + y₀*z₁) + ∆x*∆y*∆z /3
∆U_y =1/2∆y*(x₁*z₀ + x₀*z₁) + ∆x*∆y*∆z /3
∆U_z = 1/2∆z*(x₁*y₀ + x₀*y₁) + ∆x*∆y*∆z /3

∆U_x =5/2*(278*35000 + 275*33000) + 5*3*(-2000)/3=47002500
∆U_y =3/2*(240*35000 + 235*33000) + 5*3*(-2000)/3=24222500
∆U_z = -2000/2*(240*275 + 235*278) + 5*3*(-2000)/3=-131340000
∆U_x +∆U_y +∆U_z = 47002500+24222500-131340000= -60115000
