Answer: a) -A tax cut
-Additional spending on national park facilities
b) Expansionary fiscal policy
Explanation:
Fiscal Policy refers to how the government of a country is using it's spending and taxes to influence Economic conditions on a Macro level.
The keywords for this question are TAXES and SPENDING.
The means that a Discretionary FISCAL policy includes Taxes and Spending.
Now the way to close the Recessionary gap that is opening is to put more money into the Economy. The Government can do this by REDUCING TAXES which will means people have more money to spend and ADDITIONAL SPENDING on NATIONAL PARK FACILITIES as this means that the government is pumping more money into the Economy.

This is where the Government aims to put more money into the economy so that growth can be acheived and they do this by lowering taxes and increasing spending either singularly or simultaneously.
Answer:

And we can solve for y and we got:

And using condition (1) we can solve for x and we got:

So then the minimum cost for this case would be:

Explanation:
For this case the graph attached illustrate the problem for this case
We know that the total area is 60000, so then we have:

If we solve for x we got:
(1)
Now we can define the cost function like this:


We can use the condition (1) and if we replace in the cost function we have:

Since we need to minimize the cost, we can derivate the function in terms of y and we got:

And we can solve for y and we got:

And using condition (1) we can solve for x and we got:

So then the minimum cost for this case would be:

Answer and Explanation:
d. is the Fed's primary monetary policymaking body.
D is. It's very wrong to underestimate somebody's abilities or knowledge. We should never do that. It's also rude.
