A medical equipment industry manufactures X-ray machines. The unit cost C (the cost in dollars to make each X-ray machine) depen

earnstyle [38]

Answer:

$11988

Step-by-step explanation:

Given that,

The unit cost is given by :

$C(x)=0.7x^2-462x+88218$

We need to find the minimum unit cost.

For minimum cost,

Put $\dfrac{dC}{dx}=0$

So,

$\dfrac{d}{dx}(0.7x^2-462x+88218)=0\\\\1.4x-462=0\\\\x=\dfrac{462}{1.4}\\\\x=330$

Put x = 330 in equation (1).

$C(330)=0.7(330)^2-462(330)+88218\\\\=\$11988$

So, the minimum unit cost is equal to $11988.

Y and x have a proportional relationship, and y = 9 when x = 2. What is the value of y when x = 3?

Illusion [34]

Correct formula is y = kx, where k is the "constant of proportionality."

If y = 9 when x = 2, then 9 = k(2), or k = 9/2.

Then y = (9/2)x.

If x = 3, y = (9/2)(3) = 27/2 (answer)
