4. Where in the ocean does the water droplet need to be located in order to evaporate?
weeeeeb [17]

Answer:

C or D most likely C

Step-by-step explanation:

Definitely not A or B they don’t matter or make sense.. C makes more sense because it’s directly hit with heat needed to evaporate, for D to be lower it’ll take longer if at all to evaporate because it’s colder closer to the sea floor

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
