Answer: Straight line PPF, Opportunity cost is constant.
Explanation:
The PPF for Sweden is downward sloping straight line which depicts that the resources that are used in the production of these two goods are not specialized and the same set of resources is equally useful in producing both smartphones and tablets. Thus, Sweden's opportunity cost of producing more smartphones and fewer tablets should remain constant.
Answer:
3. Correctly ignored a sunk cost
Explanation:
Sunk costs refer to those costs which have been incurred in the past, which are non recoverable and which have no current or future benefits.
Sunk costs are considered as irrelevant for decision making process as they do not relate to current period and have no future implications. For example, research and development expenditure incurred in the past represents a sunk cost.
In the given case, the ticket for opera was already purchased for $100 which can now neither be recovered nor transferred. Thus this cost is irrelevant for decision making as expenditure has already been made. When Shen decided to go for a party instead of the concert, Shen has correctly ignored a sunk cost.

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:
B. Chat
Explanation:
A. Antivirus is a program that runs on your computer and prevents it from being infected by stuff encountered on the Internet.
B. Chat is a messaging service that uses the Internet to work. It's not a classical Internet service like the Web or email, but that's the closest thing in your answer choices.
C. A Firewall is another form of protection from the Internet, it blocks certain communications, but a firewall is not a service and it's not Internet-based.
D. Router is a machine that directs traffic between computers, not a service.
