Business Mathematics EXAM WS 2022-2023
P(x,y) = 8x + 10y – 0.1(x2 + xy + y2) - 1000
Find the production level that produces a maximum profit Question 11: Solve the system of equations by using the augmented matrix: 2x + 2z = 12 2x + y + 3z = 15 -3y + z = 7 Question 12: Let x denote the level of output of a firm’s production process. The cost function is given by C (x) = 0.8x(x -2)+100 and the demand function of the product by x =400 - 5p. (a) Compute profit E(x). (b) Find the output x at which profit is maximized. 1-savol: A= {1;3;6} va B= {2;6} to‘plamlarning birlashmasi, kesishishi, ayirmasi va dekart ko‘paytmasini tuzing. 2-savol: Quyidagi funksiyalarning domenini, diapazonini va nollarini toping: f(x)= 〖5ⅇ〗^x-20 g(x)= 24 lnx-12 h(x)= 〖2x〗^2-10x 3-savol: Quyidagi funksiyaning hosilasini hisoblang va mahalliy ekstremallarni toping: f(x)=√(x^2+4)⋅ⅇ^(x^2 ) 4-savol: Quyidagi funksiyalarning birinchi hosilalarini hisoblang: f(x)=x^3⋅lnx g(x)=ln(〖3x〗^3+12x) h(x) 〖=ⅇ〗^2x⋅〖ln(3〗〖x+1〗) 5-savol: Ushbu funktsiyalarni konkavlik uchun tekshiring: f(x)=" " x^4-24x^2 g(x)=" " 〖 x〗^3-4,5x^2+6x 6-savol: Kompaniyaning marjinal daromadi quyidagicha ifodalanadi: MR=100-2Q, bu erda Q - bir davr uchun sotilgan birliklar soni. Agar Q=0 da umumiy daromad 0 ga teng bo‘lsa, umumiy daromad funksiyasini toping. 7-savol: Lorenz funksiyasi L(x)=x^3 uchun Jini koeffitsientini hisoblang. 8-savol: Muayyan mahsulot uchun talab funksiyasi P=50-3Q, taklif funksiyasi esa P=10+Q^2 ga teng. Iste'molchi profitsiti va ishlab chiqaruvchining ortiqcha miqdorini hisoblang. 9-savol: 2021 yilda Germaniya yalpi ichki mahsuloti taxminan 4,26 trillion AQSH dollarini tashkil qildi. Aholisi 83 millionga yaqin edi. A. 2021-yilda aholi jon boshiga YaIMni hisoblang. B. YaIM 1%, aholi 0,4% ga o‘sdi deylik, 2022-yilda aholi jon boshiga YaIMni hisoblang. C. Faraz qilaylik, ikkala stavka ham o'zgarmas bo'lib qolsa, aholi jon boshiga yalpi ichki mahsulot qachon 55 000 AQSh dollariga yetadi? 10-savol: A mahsulotining x birligini va B mahsulotining y birligini ishlab chiqarish natijasida olingan foyda model bo'yicha taxminiy hisoblanadi. P(x,y) = 8x + 10y – 0,1(x2 + xy + y2) - 1000 Maksimal foyda keltiradigan ishlab chiqarish darajasini toping 11-savol: Kattalashtirilgan matritsa yordamida tenglamalar tizimini yeching: 2x + 2z = 12 2x + y + 3z = 15 -3y + z = 7 12-savol: X firmaning ishlab chiqarish jarayonining ishlab chiqarish darajasini bildirsin. Xarajatlar funksiyasi C (x) = 0,8x(x -2)+100 va mahsulotning talab funksiyasi x =400 - 5p bilan berilgan. (a) E(x) foydani hisoblash. (b) foyda maksimal bo'lgan x mahsulotini toping.
