Answer 1

Answer:

The answer is confirmed 1.  Just took it.

Step-by-step explanation:

Answer 2

Answer:

Company 1 is greater.

Step-by-step explanation:

Given,

The function that shows the production cost of company 1,

$f(x)=0.15x^2-6x+400$

Differentiating with respect to x,

We get,

$f'(x)=0.30x-6$

Again differentiating,

$f''(x)=0.30$

For minimum or maximum,

f'(x) = 0,

$\implies 0.3x-6=0$

$\implies x = 20$

Since, at x = 20, f''(x) = Positive,

So, f(x) is minimum at x = 20,

⇒ Minimum cost in company 1 is,

$f(20)=0.15(20)^2-6(20)+400$

$=340$

Also, by the given table,

The minimum cost of company 2 is at x = 70,

g(70) = 55,

Since, 340 > 55,

Hence, Based on the given information, the minimum production cost for company 1 is greater.
