Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find endpoints from graph</em>

Point (-3, -3)

Point (4, 2)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(4- -3)^2+(2- -3)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{7^2+5^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{49+25}$
[√Radical] Add: $\displaystyle d = \sqrt{74}$

A firm manufactures a commodity at two different factories. The total cost of manufacturing depends on the quantities x and y su

SVETLANKA909090 [29]

Answer:

Each factory should supply 100 units

x = 100 units

y = 100 units

Step-by-step explanation:

Since the total production must be 200 units, then x + y = 200.

The cost function can be rewritten as a function of 'x' as follows:

$y=200-x\\C=f(x,y) =2x^2+xy+2y^2+500\\C= f(x) = 2x^2+x(200-x)+2(200-x)^2+500\\C= f(x) = x^2+200x+500+2(x^2-400x+40,000)\\C= f(x) = 3x^2-600x+80,500$

The value of 'x' for which the derivate of the cost function is zero, is the production level that minimizes cost:

$C= f(x) = 3x^2-600x+80,500\\C'= f'(x)=0 = 6x-600\\x=100\ units\\y = 200 -x = 100\ units$

In order to minimize production costs, each factory should supply 100 units
