Answer:
Value of x maximising profit : x = 5 
Explanation:
Cost : C(x) = x^3 - 6x^2 + 13x + 15 ; Revenue: R(x) = 28x
Profit : Revenue - Cost = R(x) - C(x) 
28x - [x^3 - 6x^2 + 13x + 15]  = 28x - x^3 + 6x^2 - 13x - 15
 = - x^3 +  6x^2 + 15x - 15
To find value of 'x' that maximises total profit , we differentiate total profit function with respect to x & find that x value.
dTP/dx = - 3x^2 + 12x + 15 = 0 ► 3x^2 - 12x - 15 = 0 
3x^2 + 3x - 15x - 15 = 0  ► 3x (x +1) - 15 (x + 1) = 0 ► (x+1) (3x-15) = 0 
x + 1 = 0 ∴ x = -1   [Rejected, production quantity cant be negative] ; 
3x - 15 = 0 ∴ 3x = 15 ∴ x = 15/3 = 5 
Double derivate : d^2TP/dx^2 = - 6x + 12 
d^2TP/dx^2  i.e - 6x + 12  at x = 5 is -6(5) + 12 = - 30+ 12 = -8 which is negative. So profit function is maximum at x = 5 
 
        
             
        
        
        
Answer:
 c. the trade balance and the exchange rate.
Explanation:
An Open Economy is an economy that allows the free inflow and outflow of goods, services, capital and people. The opposite of a closed economy.
What sets these two models apart is that in an open economy, both imports and exports are allowed, so that countries necessarily have to trade in more than one currency, so the exchange rate must be examined. In addition, business transactions are recorded in a balance of payments. So these are the two concepts that are not tried in a closed economy analysis, but are introduced in an open economy.
