Answer:
Equation is
Step-by-step explanation:
Number of seats = 200
Cost of building a airplane with 200 seats = 100 million
As cost of dollars,c, is proportional to the number of seats,s,
where k is any constant.
Put
Now put in
So, the equation which can be used to determine the cost,in millions of dollars to build an airplane with any number of seats is
Thing I no this one I just forgot
The formula to the pythagorean theorem is : a^2 + b^2 = c^2
