The policy is not practical because it is not enforceable. Lots of shops or businesses will not practice this as it will scare customers away.
<h3>Why is the policy not fair?</h3>
The policy is not fair because throw away paper is recyclable while plastic bags are not. Hence people who use paper should not be charged as much as those who use plastic bags, if at all.
<h3>What is the saving due if a person brings their own container to bag their groceries?</h3>
They most likely wills save 5% on every purchase made.
<h3>Why are environmental policies important?</h3>
The goal of environmental law is to safeguard the
- land,
- air,
- water, and
- soil.
Infractions of these rules result in a variety of penalties, including fines, community service, and, in severe circumstances, jail time.
Without environmental regulations, the government would be unable to penalize people who harm the environment.

Answer:
The present value of the machine is $35499
Explanation:
The annual amount or annuity amount = $4010 per year.
Total number of years = 13 years
Here, the interest rate is not given so we just assume the interest rate = 6% per annum.
Since we have a total number of years and annual payment that occurs for 13 years. We are required to find the present value of the machine. So use the formula to find the present value of the annuity.
The present value of machine = (Annuity amount x (1 – (1+r)^-n) ) / r
The present value of machine = (4010(1 – (1+6%)^-13) ) / 6%
The present value of machine = $35499
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.
