Explain the effects of each of the following factors on the market price and quantity of cell phones available in the market:
An increase in consumers’ income = if there is an increase in consumers income, there may be a decrease in the cell phones available for purchase because more people would have money to purchase phones. If more people are willing and able to purchase phones, the market price may increase on the device.
Technical improvements that reduce production costs = If production costs of the devices go down, the market price may decrease making the phones more affordable. If phones become more affordable and decrease in price, the quantity sold may rise to reflect the change.
A sharp decline in the cost of making fixed-line calls = if the cost of making fixed-line calls decreases, there may not be any change to the market price of phones however their may be an increase in quantity sold.

Explanations: Many companies go by that standard although they don't necessarily mean it. They are very much aware of how much a customer is important to the company. They should be aware of all the staff and how they are treating the customers, the quality of a product and generally give their best to please someone when they come inside their store.
However there should be certain precautionary measures taken if they encounter with a customer that, beside all the kindness you were offering, is rude, frantic, starts damaging the goods, ambience etc.
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.
