When we compose functions, we must make sure that the output of the first function is part of the _____of the second function.
A.) domain
~Hope this answers your question!~
The revenue is given by the product of the price and the demand function
- The revenue function for Sky Eagle is <u>RS = 229·PS - 0.60·PS² + 0.35·PS·PH</u>.
- The revenue function for Horizon is <u>RH = 269·PH + 0.10·PS·PH - 0.64·PH²</u>.
Reasons:
The given parameters are;
The demand function for the Sky Eagle, DS = 229 - 0.60·PS + 0.35·PH
The demand function for the Horizon, DH = 269 + 0.10·PS - 0.64·PH
The above demand functions gives the quantity demanded
Therefore, the revenue function is given by the product of the price and the demand function as follows;
RS = PS × DS = PS × (229 - 0.60·PS + 0.35·PH) = 229·PS - 0.60·PS² + 0.35·PS·PH
The revenue for Sky Eagle <u>RS = 229·PS - 0.60·PS² + 0.35·PS·PH</u>
<u />
Revenue for Horizon is found as follows;
RH = PH ×(269 + 0.10·PS - 0.64·PH) = 269·PH + 0.10·PS·PH - 0.64·PH²
The revenue for Horizon, <u>RH = 269·PH + 0.10·PS·PH - 0.64·PH²</u>

It is given in the question that, A commercial airline makes a flight each day from New York to Paris .
So in a week, the airline makes 7 flights .
And the aircraft seats 524 passengers, and serves 2 meals 2 each passenger per flight .
It means, for one passenger, one flight , aircraft serves 2 meals.
So for 524 passengers, 7 flights, aircraft serves

You would minus 12 on both sides which would give you d= -16.8 meters it’s a negative answer btw
Hope this helps
