According to ADA guidelines, at most, an incline can be 8.5°. Is the following incline acceptable? If yes, prove it. If not, explain why and change one dimension in the design so that it would be.​

Let the angle is x.

We have:

Since 9.5° > 8.5° it is not acceptable.

If the angle is 8.5° and the height is x, then we have:

The height is at most 13.45 ft

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
