Answer:
B
Explanation:
First, a monopoly produce less than the socially efficient quantity because as the figure shows, the quantity produced is determined by the intersection between the marginal cost curve (MC) and the marginal revenue curve (MR) and not by the intersection between the MC and the demand. For instance, there is a deadweight loss (shown by the figure).
Second, equilibrium price is always higher than in a competitive market because is always higher than the MC. The price is determined by the equilibrium quantity (found before) and the demand. Also, there are barries to entry and so monopolist have always price control.

As interest rates rise, the prices of existing bonds will fall.
A fundamental principle of bond investing is that market interest rates and bond prices generally move in opposite directions. When market interest rates rise, prices of fixed-rate bonds fall. this phenomenon is known as interest rate risk.
Interest rates will always change, and no one can predict how they will change over time. Whether interest rates are rising or falling, it’s vital to consider your yield to maturity for any bond purchase and compare it with what you could get if you were to buy a new bond.

Answer:
True.
Explanation:
Messaging systems range from semi-public systems such as standard text messaging on mobile phones, to private systems that are closed to anyone outside of invited members.
A messaging system can be defined as an electronic device which enables users to send text messages to one or more users depending on the configuration and it ranges from semi-public systems to private systems.
In a semi-public messaging system, messages can be sent between users with little or no restriction to who can send or receive these messages. An example is sending short standard text on mobile phones.
On the other hand, a private messaging system is a type of system that denies access to individuals outside of the group, only invited members are able to send and receive messages.
Answer: The change in revenue for the sale of 1 more doghouse $ 66.67 dollars
Explanation: Differential is a function that can be used to approximate function value with a great degree of accuracy. This is done by the following.
Mathematical definition of derivative: f'(x) = lim f(x+Δx) - f(x)/Δx.
If Δx is very small:
f'(x) . Δx ≅ f(x+Δx) - f(x)
Knowing that Δy ≅ f(x+Δx) - f(x) and the diferential of variable x can be written by dx as the variable y can be dy:
dy = f'(x) dx
which means that the differential dy is approximately equal to the change Δy, if Δx is very small.
For the question, R(x) = y(x) = 14,000ln(0.01x+1)
f'(x) = ![\frac{d[14,000.ln(0.01x+1)]}{dx}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5B14%2C000.ln%280.01x%2B1%29%5D%7D%7Bdx%7D)
Using the chain rule, the derivative will be:
f'(x) = 14,000.
dy = 14,000..dx
dx is the change in x. For the question, the change is 1 (1 more doghouse) and x is 110:
dy = 14,000
dy = 
dy = 66.67
The change in revenue is $66.67 dollars.
