Need some help with macroeconomics !
Korolek [52]

The monetary policy that the Central Bank is using to address the downturn in the economy is the reduction of the reserve requirement from 17% t 14%.

<h3>What is monetary policy?</h3>

It should be noted that the monetary policy is the set of actions to control money supply in the economy.

The macroeconomic issues resulting from the pandemic on Trinidad and Tobago are that there are less money in circulation and there's a reduction in the standard of living.

The reduction of the reserve requirement will impact the money supply as it will lead to more money in circulation.

<u>Complete question:</u>

1. What form of monetary policy can the Central Bank use to address the downturn in the economy resulting from the pandemic?

2. Identity and explain two macroeconomic issues resulting from the pandemic on Trinidad and Tobago.

3. Identify how the reserve requirement will impact the money supply.

The best thing to do is to break it down to very small parts.

You are dealing with a sum. The first phrase says

10 +

Never mind the rest of it for now. Just make sure you understand that you are adding 10 to something.

The next part of the question a quotient. You have to understand exactly what that means. If you divide 15 by three, you would write that as 15/3 The answer you get is 5. 5 is the quotient. It's a fancy way of saying answer.

Algebra isn't so nice. There is no way to get an answer when you do a division with a number and a letter. You have to be content with just showing how it is done.

So the next phrase is x divided by 6. And you show that as x/6

So what do you have? 10 + something which is where we left off. The something is x/6

Answer

10 + x/6

A potter forms a piece of clay into a cylinder. as he rolls it, the length L, of the cylinder increases and the radius, r, decre
shutvik [7]
The only way I've done this is with calculus and derivatives.

Basically, you need a formula that dictates what is going on.
In this case that formula is Volume=Area*Length
However because we do not know the area but instead the radius, You need to put the formula in terms of the radius: Volume = π*(radius^2)*length

Then I would make a list of all the variable that you know:
(PS. I would first make sure that all the units in the problem are the same.  If not, adjust them so they are the same)
Volume: Find the volume at the set point in time by using this formula and plugging in the values of 2cm and 6cm for the radius and the length respectively.
This makes <span>Volume=24π
</span>It was also given that at the set time, the radius= 2 and length=6

However, we also need the rates of change for each of these variables.
A rate of change is a derivative so I will call them dv/dt, dr/dt. and dL/dt for the volume, radius, and length.
Since, we are finding dr/dt, we leave it as the variable dr/dt.
dL/dt was given as .4 (it is positive because it is increasing)
This is where you need common sense and a basic understanding of rate of change: dv/dt is 0 because even though it was not technically given, no clay is added or taken away so the volume must stay constant making how much it changes by equal to 0.

Now that we have the list, it is time to return to the formula.  First though we need to take the derivative of the formula.  Thus,
Volume = π*(radius^2)*length
becomes: 
dv/dt=(π*(radius^2)*dL/dt) + (2π*radius*length*dr/dt)
This was done with the product rule for derivative if you did not figure it out.

Then plug in the numbers from the list:
0=(π*4*.4)+(2π*2*6*dr/dt)
Then solve algebraically.
1.6π+24π*dr/dt=0
24π*dr/dt=-1.6π
dr/dt=-1/15

Then add units based on the problem:
-1/15 cm/second is the rate at which the radius is increasing (because it is negative, the radius is actually decreasing).
