A board is 85cm in length and must be cut so that one piece is 11cm longer than the other piece . Find the length of each piece.

iVinArrow [24]

The shorter piece is 37 cm

The longer piece is 48 cm:

Step-by-step explanation:

Divide 85 cm by 2 = 42.5

Divide 11 cm by 2 = 5.5

Add them together = 48 cm

85 cm - 48 cm = 37 cm

) If the average cost function for a company is given by C(x) = 0.2x + 20x −1 + 75, nd what level of production produces the low

Stells [14]

Answer:

The correct answer is 10 for lowest average cost and the cost function is 0.2 $x^{2}$ + 75x + 20.

Step-by-step explanation:

Average cost function is given by = $\frac{Cost}{Quantity}$ = C(x) = 0.2x + $\frac{20}{x}$ +75.

For minimizing we need to find $\frac{d}{dx}$ C(x) = 0.

⇒ $\frac{d}{dx}$ C(x) = 0.2 - $\frac{20}{x^{2}}$ .

⇒ $\frac{20}{x^{2}}$ = 0.2

⇒ $x^{2}$ = 100.

⇒ x = ±10

⇒ x = 10 ; cost cannot be negative.

Second order derivative is positive which implies the average cost minimizes.

Original cost function is given by C(x) × x = 0.2 $x^{2}$ + 75x + 20.
