Answer:

49

Step-by-step explanation:

The cost function is the sum of the costs as a function of the number of bins made.

C(x) = 4x + 18424

The profit function is the difference between the revenue and the cost functions.

P(x) = R(x) - C(x)

P(x) = -2x^2 + 478x - (4x + 18424)

P(x) = -2x^2 + 474x - 18424

The smallest break-even point is the smallest value of x at which profit is zero. Zero profit means there is no gain and no loss.

P(x) = -2x^2 + 474x - 18424 = 0

x^2 - 237x + 9212 = 0

9212 = 2^2 * 7^2 * 47

(x - 188)(x - 49) = 0

x - 188 = 0 or x - 49 = 0

x = 188 or x = 49

Answer: 49

What is the domain of the function
Ksenya-84 [330]

Answer:

x\geq -6

Step-by-step explanation:

The domain of a function is all of the values that x can be under that specific function. In this case, we're asking what values of x allow \sqrt{\frac{1}{3} x+2} to exist.

In order for square roots to exist, the quantity under the square root must be greater than or equal to 0, because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for x:

\frac{1}{3}x+2\geq 0

Solving this inequality, we get:

\frac{1}{3}x+2\geq 0

\frac{1}{3}x\geq -2 (Subtract 2 from both sides of the inequality to isolate x)

x\geq -6 (Multiply both sides of the inequality by 3 to get rid of x's coefficient)

Hope this helps!
