Export integral.
B
Definite integral.
C
Antiderivative integral
D
Indefinite integral.

Seçenekler
A
The consumers’ cut.
B
The consumers’ income.
C
The consumers’ surplus.
D
The consumers’ revenue.
E
The consumers’ choice.
Açıklama:
The price difference between the current price in the market and the price that consumers are willing to pay is called the consumers’ surplus, which is the area under the demand curve and above the equilibrium price level.
Soru 3

Seçenekler
A
The consumers’ income.
B
The consumers’ surplus.
C
The consumers’ rate.
D
The consumers’ integral.
E
The consumers’ outcome.
Açıklama:
The consumers’ surplus is the area under the demand curve and above the equilibrium price level.

To calculate the area of the slope.
B
To find the slope of the curve.
C
To estimate the curve shape.

Which of the following can be an example for a continuous flow of income?
Seçenekler
A
A rock star receiving a continuous income stream from recording royalties.
B
A company manufacturing cars.
C
A government administration collecting tax.
D
An artist creating a painting.
E
A worker working in a factory for a long period.
Açıklama:
It may seem that a continuous flow of income is unrealistic and has no place in the real world, but that is not true. For example, rock stars receive a continuous income stream from recording royalties. To give a more familiar example, we can think of oil companies that pump oil daily or night, which would mean a continuous stream of income as the oil is sold.
Soru 9
If a payment is not one time only for each year but is continuous, how do we calculate the present value?
Seçenekler
A
Making surplus equations.
B
Calculating the area under the curve.
C
Using the integral technique.
D
Using advanced trigonometry.
E
Recording yearly data for at least a decade.
Açıklama:
If apayment is not one time only for each year but is continuous, we can calculate the present value using the integral technique.
Soru 10
Since the producers’ surplus is between a specific area, which integral is most suitable in order to find it?

A
The definite integral.
B
The antiderivative integral.
C
The slope integral.
D
The continuous interval
E
The trigonometric interval.
Açıklama:
Same as the consumers’ surplus, since the producers’ surplus is between a specific area, the definite integral is most suitable in order to find it.
