a manufacturer has determined that if his company sells x items per day then their profit is given by P=-x^2+ 700 x-10000 euros.

Radda [10]

Answer:

15

Step-by-step explanation:

To find the minimum amount of items, x, that need to be sold for the manufacturer to make a profit, we can use the quadratic formula

$x = \frac{-b+\sqrt{b^{2}-4ac } }{2a}; x= \frac{-b-\sqrt{b^{2}-4ac } }{2a}$

$x= \frac{-700+\sqrt{700^{2}-4(a)(-10000) } }{2(1)}; x= \frac{-700-\sqrt{700^{2}-4(a)(-10000) } }{2(1)}$

$x= \frac{-700+\sqrt{530000} }{2}; x= \frac{-700-\sqrt{530000} }{2}$

$x=\frac{-700+100\sqrt{53} }{2}; x=\frac{-700-100\sqrt{53} }{2};$

$x=-350 + 50\sqrt53 = 14.005; x = -350 - 50\sqrt53 = -714.005$

In context of the problem, we can only rely on the positive value, as the negative value would lead to a loss of profit.

$(-714.005)^2+700(-714.005)-10000=-0.360$

Furthermore, we must round to the nearest whole number, as you cannot make part of an item.

Lastly, if you were to plug in 14 into the equation for Profit, you would still have a negative number (i.e. a negative profit), thus requiring the manufacturer to make no less than 15 items to make a profit:

$(14)^2+700(14)-10000=-4\\\\(15)^2+700(15)-10000=725$

I need help with these three problems.... please help me????

12. Answer: 2130

Step-by-step explanation:

T = -0.01y + 10.6

9.2 = -0.01y + 10.6

-10.6 -10.6

-1.4 = -0.01y

÷-0.01 ÷-0.01

140 = y

"y" represents the number of years after 1990

1990 + 140

= 2130

13. Answer: -0.0036° per foot

Step-by-step explanation:

Since the relationship is linear, then we can set up the values as x, y coordinates and use the slope formula to find the rate of degrees over feet.

(6562, 63) and (16405, 28)

rate = $\frac{28 - 63}{16405-6562}$

= $\frac{-35}{9843}$

= $\frac{-0.0036}{1}$

**************************************************************

14. Answer: $0.28 per kWh

Step-by-step explanation:

Same reason as #13

(200, 55) and (500, 140)

rate = $\frac{140-55}{500-200}$

= $\frac{85}{300}$

= $\frac{0.28}{1}$
