<h3>Answer:    (x+7)^2 + (y+2)^2 = 4</h3>

===========================================================

Explanation:

The center is at (h,k) = (-7,-2)

h = -7

k = -2

The radius is r = 2 units

Plug these three pieces of info into the template below and simplify

(x-h)^2 + (y-k)^2 = r^2

(x-(-7))^2 + (y-(-2))^2 = (2)^2

(x+7)^2 + (y+2)^2 = 4

You can use a tool like Desmos or GeoGebra to confirm the answer.

a gift shop sells 160 wind chimes per month at $150 each. the owners estimate that for each $15 increase in price, they will sel
adell [148]

Answer:

The price per wind chime that will maximize revenue = $ 315

Step-by-step explanation:

Given - A gift shop sells 160 wind chimes per month at $150 each. the owners estimate that for each $15 increase in price, they will sell 5 fewer wind chimes per month.

To find - Find the price per wind chime that will maximize revenue.

Proof -

Given that,

Total Wind chimes selling = 160

Price of each Wind chime = $150

Now,

Given that, for each $15 increase in price, they will sell 5 fewer wind chimes per month.

So,

Let the price = 150 + 15x

So,

Number of wind Chimes sold per month = 160 - 5x

So,

Total Revenue, R = (150 + 15x)(160 - 5x)

                             = 24000 - 750x + 2400x - 75x²

                             = 24000 + 1650x - 75x²

⇒R(x) = 24000 + 1650x - 75x²

Differentiate R with respect to x , we get

R'(x) = 1650 - 150x

Now,

For Maximize Revenue, Put R'(x) = 0

⇒1650 - 150x = 0

⇒150x = 1650

⇒x = 1650/150

⇒x = 11

∴ we get

Price per Wind chime = $ 150 + 15(11)

                                    = $ 150 + 165

                                    = $ 315

So,

The price per wind chime that will maximize revenue = $ 315

Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.
inysia [295]
<h2>Hello!</h2><h2>Let me help you.</h2>

As I understand, you need to write an equation that relates t \ and \ y. This problem will be solved using equations. The problem states:

<em>Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.</em>

<em />

From this statement, we know that:

t: Number of candies Nick bought.

y: Number of friends.

Since I am included in this problem, the number of people involved here can be expressed as:

y+1

Since each of us got 7 candies, then it is true that:

\frac{t}{y+1}=7 \\ \\ t=7(y+1)

<em>So t (number of candies) is a function of y(number of friends).</em>
