The distance formula is the square root of (X2 - X1)^2 + (y2 - y1)^2. Let D = y and c = x. Plug in the numbers now. Your equation is now the square root of ( -3 - (-5)) ^2 + (-2 - (-4))^2. Now complete it, your answer is 2.82...

Find the minimum cost of producing 60000 units of a product, where x is the number of units of labor, at $99 per unit, and y is
Y_Kistochka [10]

Answer:

The minimum cost of producing 60000 units of a product is $105867

Step-by-step explanation:

Since x is the number of units of labor, at $99 per unit, and y is the number of units of capital expended, at $84 per unit, The cost C(x,y) is given by:

C(x, y) = 99x + 84y

P(x, y) = 100x^{0.25}y^{0.75}

For the minimum cost:

100x^{0.25}y^{0.75}=60000\\x^{0.25}(\frac{33x}{28} )^{0.75}=600\\x^{0.25}(\frac{33}{28} )^{0.75}x^{0.75}=600\\x^{0.25+0.75}*1.131=600

Using the langrage multiplier,

99=0.25(100)x^{-0.75}y^{0.75}\lambda...(1\\84=0.25(100)x^{0.25}y^{-0.25}\lambda...(2

Dividing both equation 1 and 2

y=\frac{33}{28}x

Substituting y=\frac{33}{28}x in 100x^{0.25}y^{0.75}=60000, we get:

x_{min}=530.44 labor units

Substituting x_{min}=530.44  labor units in y=\frac{33}{28}x, we get

y_{min}=\frac{33}{28}*530.44=625.16 labor unit

C(x, y) = 99x + 84y=99(530.44)+84(635.16) = $105867\\

The minimum cost of producing 60000 units of a product is $105867
