The systems development life cycle in which model developers use a model to generate functional requirements and physical design specifications simultaneously is:
<h3>What is a Model?</h3>
This is a prototype which is used to represent a real thing to show the real life scenarios and applications on a much smaller scale.
With this in mind, we can see that in the prototyping life cycle, the model developers make functional requirements simultaneously to find out how the physical design specifications would look like.

Answer:
2.8%
Explanation:
The formula to calculate value of a perpetuity is as follow:
V = Annuity payment in year 1 / (r-g)
V: Value of the perpetuity
r: Discount rate
g: Growth rate (missing value)
By inputting numbers into the formula, we have:
6225.81 = 386 / (0.09 - g)
--> g = 2.8%
Answer:
1. 20 units
2. $600
Explanation:
1. 
MC = 4q
Price, P = $80
For maximizing profits,
Marginal cost = Price of the commodity
4q = 80
q = 20 units


= 200 + 800
= 1,000
2. Profit = Total revenue - Total cost
= (Price × Quantity) - TC
= (80 × 20) - $1,000
= $1,600 - $1,000
= $600
3. We know that the firm in the short run will be produce at a point where total revenue is greater than the total variable cost
Average variable cost = variable cost ÷ quantity

= 2Q
MC = 4Q
Here, MC is greater than AVC at any given point.
so in the short run firm will producing short run positive profit.
