When ur looking at the graph of ur inequality, u will see a shaded region.....all the points in the shaded region are ur possible solutions. So when u plot ur ordered pair, if it falls in the shaded region, it is a solution...if it does not fall in the shaded area, it is not a solution.

There are approximately 3.2 x 10^7 mosquitoes near each backyard pool. How many total mosquitoes are thre in a city with 6.7 x 1
dexar [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

There are approximately 3.2 \times 10^7 mosquitoes near each backyard pool.

The city has total number of pools 6.7 \times 10^{12}.

So the total mosquitoes will be : 3.2 \times10^7 \times6.7\times 10^{12}

So the total mosquitoes will be : 21.44 \times 10^{19}

So the total mosquitoes will be : 2.144 \times 10^{20}  :   Answer

Hope it will help :)

The distance from P to Q is four times the distance from Q to R. The distance from p to r is 120 metres. What is the distance fr
Leviafan [203]
|----------------------------------120 m ------------------------------|

|--------------|--------------|--------------|--------------|--------------|
P                                                                 Q               R

Distance from P to R = 120m

120 ÷ 5 = 24m

The distance from Q to R is 24m.

Given P = x^0.3 y^0.7 is the chicken lay eggs production function, where P is the number of eggs lay, x is the number of workers
lora16 [44]

Answer:

Part A)

\displaystyle \frac{dy}{dx}=-\frac{3}{7}P^\frac{10}{7}x^{-\frac{10}{7}}

Part B)

The daily operating cost decreases by about $143 per extra worker.

Step-by-step explanation:

We are given the equation:

\displaystyle P=x^{\frac{3}{10}}y^{\frac{7}{10}}

Where <em>P</em> is the number of eggs laid, <em>x</em> is the number of workers, and <em>y</em> is the daily operating budget (assuming in US dollars $).

A)

We want to find dy/dx.

So, let’s find our equation in terms of <em>x</em>. We can raise both sides to 10/7. Hence:

\displaystyle P^\frac{10}{7}=\Big(x^\frac{3}{10}y^\frac{7}{10}\Big)^\frac{10}{7}

Simplify:

\displaystyle P^\frac{10}{7}=x^\frac{3}{7}y

Divide both sides by<em> </em>the <em>x</em> term to acquire:

\displaystyle y=P^\frac{10}{7}x^{-\frac{3}{7}}

Take the derivative of both sides with respect to <em>x: </em>

\displaystyle \frac{dy}{dx}=\frac{d}{dx}\Big[P^\frac{10}{7}x^{-\frac{3}{7}}\Big]

Apply power rule. Note that P is simply a constant. Hence:

\displaystyle \frac{dy}{dx}=P^\frac{10}{7}(-\frac{3}{7})(x^{-\frac{10}{7}})

Simplify. Hence, our derivative is:

\displaystyle \frac{dy}{dx}=-\frac{3}{7}P^\frac{10}{7}x^{-\frac{10}{7}}

Part B)

We want to evaluate the derivative when <em>x</em> is 30 and when <em>y</em> is $10,000.

First, we will need to find <em>P</em>. Our original equations tells us that:

P=x^{0.3}y^{0.7}

Hence, at <em>x</em> = 30 and at <em>y</em> = 10,000, <em>P </em>is:

P=(30)^{0.3}(10000)^{0.7}

Therefore, for our derivative, we will have:

\displaystyle \frac{dy}{dx}=-\frac{3}{7}\Big(30^{0.3}(10000^{0.7})\Big)^\frac{10}{7}\Big(30^{-\frac{10}{7}}\Big)

Use a calculator. So:

\displaystyle \frac{dy}{dx}=-\frac{1000}{7}=-142.857142...\approx-143

Our derivative is given by dy/dx. So, it represents the change in the daily operating cost over the change in the number of workers.

So, when there are 30 workers with a daily operating cost of $10,000 producing a total of about 1750 eggs, the daily operating cost decreases by about $143 per extra worker.
