Answer:

±2 sqrt(10) = x

Step-by-step explanation:

40 - x^2 =0

Add x^2 to each side

40 -x^2 + x^2 = 0+x^2

40 = x^2

Take the square root of each side

±sqrt(40) = sqrt(x^2)

±sqrt(40) = x

±sqrt(4*10) = x

We know the sqrt(ab) = sqrt(a) sqrt(b)

±sqrt(4) sqrt(10) = x

±2 sqrt(10) = x

A certain electronics manufacturer found that the average cost C C to produce x DVD/Blu- ray players can be found using the equa
Kisachek [45]

Answer:

83,491.67 dollars

Step-by-step explanation:

Given that a certain electronics manufacturer ound that the average cost C C to produce x DVD/Blu- ray players can be found using the equation  C=0.03x^2-5x+700

To find the minimum average cost per machine we can use derivative test.

we find first and second derivative.

If for a particular value of x first derivative is 0 and second derivative is positive, then that x satisfies the minimum cost criteria.

C=0.03x^2-5x+700\\C'(x) = 0.06x-5\\C"(x) = 0.06>0

Second derivative is always positive

I derivative =0 gives

x=5/0.06 \\=83.33\\~83

For 83 players the cost would be minimum

Minimum cost = 0.03(83)^2-5(83)+700\\=491.67
