The revenue for a company producing widgets is given by y = -20x2 - 50x + 200, where x is the price in dollars for each widget.

lisov135 [29]

Answer:

The price is x = $2.779

Step-by-step explanation:

From the question we are told that

The revenue is $y = - 20x^2 - 50 x + 200$

The cost of production is $y = 30 x - 10$

Generally at break even point the cost of production is equal to the revenue

$-20x^2 -50x + 200 = 30x-10$

=> $20x^2 +20 -210 = 0$

Using the quadratic formula to solve this equation we have that

x = $2.779

Help with 21 would be much appreciated.

Answer:

$\large\boxed{x=2\sqrt{21}\ and\ y=4\sqrt3}$

Step-by-step explanation:

Look at the picture.

ΔADC and ΔCDB are similar. Therefore the sides are in proportion:

$\dfrac{AD}{CD}=\dfrac{CD}{DB}$

We have

$AD=14-8=6\\CD=y\\DB=8$

Substitute:

$\dfrac{6}{y}=\dfrac{y}{8}$ <em>cross multiply</em>

$y^2=(6)(8)$

$y^2=48\to y=\sqrt{48}\\\\y=\sqrt{16\cdot3}\\\\y=\sqrt{16}\ cdot\sqrt3\\\\\boxed{y=4\sqrt3}$

For x use the Pythagorean theorem:

$x^2=6^2+(4\sqrt3)^2\\\\x^2=36+48\\\\x^2=84\to x=\sqrt{84}\\\\x=\sqrt{4\cdot21}\\\\x=\sqrt4\cdot\sqrt{21}\\\\\boxed{x=2\sqrt{21}}$
