When the squared terms are of different signs, the equation generally describes a hyperbola. This one has its vertices at x=±30, so the parameters of interest are
  domain: (-∞, -30] ∪ [30, ∞)
  range: (-∞, ∞)

If exactly 180 people sign up for a charter flight, Leisure World Travel Agency charges $298/person. However, if more than 180 p
lesantik [10]

Answer:

The max. revenue is $57,121.

This happens with 239 passengers.

The price of the ticket is $239 per person.

Step-by-step explanation:

Let the variable "P" denote the number of passengers.

If P=180, then the ticket cost is $298/person. Then the price is reduced by $1 for each additional person.

In general, if P=(180+x), then the ticket cost becomes (298-x) per person.

The revenue can be defined as the ticket cost multplied by the number of passengers:

R=P*T=(180+x)(298-x)=53,640-180x+298x-x^2\\\\R(x)=-x^2+118x+53,640

We can derive R and equal to zero to maximize the function.

dR/dx=-2x+118=0\\\\x=118/2=59

The amount of passengers is:

P=180+x=180+59=239

The price of the tickets is

T=298-59=239

The revenue is:

R(59)=(180+59)(298-59)=239*239\\\\R(59)=57,121

Can someone help me​
prisoha [69]
The answer is SAS.
The left side is equivalent to the right side because of the indicating dash. They also share the same angles where the curve marks are. And then lastly they share the same line (the diagonal on the inside) in the shape. Thus making it side angle side

The right triangle ABC is shown below. Find the missing side by using the Pythagorean theorem,if a=6ft and b=8ft​
docker41 [41]

Answer:

c = 10

Step-by-step explanation:

Using Pythagoras' theorem

The square on the hypotenuse of a right triangle is equal to the sum of the squares on the other 2 sides, that is

c² = a² + b² ← substitute values

c² = 6² + 8² = 36 + 64 = 100 ( take the square root of both sides )

c = \sqrt{100} = 10
