Answer:

  (x +8)² +(y +6)² = 100

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r can be written:

  (x -h)² +(y -k)² = r²

For your given values of h=-8, k=-6, r=10, the equation is ...

  (x +8)² +(y +6)² = 100

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night
zubka84 [21]

the employee earned $1813 from Nachos

Explanation:

The theater's popcorn sales is inversely proportional to nacho sales

Let theater's popcorn = P

nacho sales = N

P\text{ }\alpha\text{ }\frac{1}{N}

Equating the relationship:

\begin{gathered} P\text{ = k(}\frac{1}{N}) \\ P\text{ = }\frac{k}{N} \\ \text{where k = constant of proportionality} \end{gathered}

when theater sales = $2,254

Nacho sales = $1,628

\begin{gathered} 2254\text{ =}\frac{k}{1628} \\ k\text{ = 2254(1628)} \\ k\text{ = 3}669512 \end{gathered}

The relationship becomes:

P\text{ = }\frac{3669512}{N}

When cost of the theater popcorn = $2,024

The cost from nachos = ?

We would use the relationship to get the above:

\begin{gathered} 2024\text{ = }\frac{3669512}{N} \\ 2024N\text{ = 3669512}18 \\ N\text{ = }\frac{\text{3669512}}{2024} \\ N\text{ = }1813 \end{gathered}

Hence, the employee earned $1813 from Nachos
