Answer:
The speed of the car is 67.77 m/s and it is moving away from the observer.
Explanation:
The apparent frequency is given as
![f' = f\dfrac{ [v - vo]}{ [v - vs]}](https://tex.z-dn.net/?f=f%27%20%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D)
Here
o is the observer
s is the source which is car
v is the speed of sound = 343 m/s
f = true frequency emitted by the car (when stationary)
f ' = 0.835 f
so
![f' = f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 f= f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 = \dfrac{ [343 - 0]}{ [343 - vs]}\\0.835=\frac{343}{343-x}\\x=-67.77 m/s](https://tex.z-dn.net/?f=f%27%20%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D%5C%5C0.835%20f%3D%20f%5Cdfrac%7B%20%5Bv%20-%20vo%5D%7D%7B%20%5Bv%20-%20vs%5D%7D%5C%5C0.835%20%3D%20%5Cdfrac%7B%20%5B343%20-%200%5D%7D%7B%20%5B343%20-%20vs%5D%7D%5C%5C0.835%3D%5Cfrac%7B343%7D%7B343-x%7D%5C%5Cx%3D-67.77%20m%2Fs)
The speed of the car is 67.77 m/s and it is moving away from the observer.

Explanation:
Monotonic transformation refers to changing the quantity of both the variables in a way that their ranking or order is preserved. Monotonic transformation of a utility function does not change the marginal rate of substitution as the order of preferences remains intact with the monotonic transformation. It's just the level of utility that either increases or decreases with such a transformation. The indifference curve shape remains the same. With monotonic transformation, consumer moves from a lower to higher or higher to lower indifference curve.
Answer:

B. Not included in GDP
C. Included in GDP under consumption expenditures
Explanation:
Gross domestic product is the sum of all final goods and services produced in an economy within a given period which is usually a year.

GDP = Consumption spending on both durable and non durable goods and services + business spending on cqpital goods + Government Spending on public goods and services + Net Export
Items not included in the calculation of GDP are :
1. Transfer payments
2. Illegal activities
3. Purchase of shares
