Explain how to solve the 2020th term
Solve the 2020th term
Solving the 2020th term of a sequence using conventional method may be a little bit difficult but in questions like this, it's not.
The very first thing to do is to solve for the third term;
The value of the third term is the value of every other term after the second term of the sequence; So, what I'll do is that I'll assign the value of the third term to the 2020th term
This is proved as follows;
From the question, we have that "..... each term after the second term is the average of all of the preceding terms", in other words the MEAN
[tex]T_{n} = \frac{\sum T{k}}{n-1} ; where: k = 1 .... n -1[/tex]
Assume n = 3
[tex]T_{3} = \frac{T_1 + T_2}{2}[/tex]
Multiply both sides by 2
[tex]2 * T_{3} = \frac{T_1 + T_2}{2} * 2[/tex]
[tex]2T_{3} = T_1 + T_2[/tex]
Assume n = 4
[tex]T_{4} = \frac{T_1 + T_2 + T_3}{3}[/tex]
[tex]T_{4} = \frac{(T_1 + T_2) + T_3}{3}[/tex]
Substitute [tex]2T_{3} = T_1 + T_2[/tex]
[tex]T_{4} = \frac{2T_3 + T_3}{3}[/tex]
[tex]T_{4} = \frac{3T_3}{3}[/tex]
[tex]T_{4} = T_3[/tex]
Assume n = 5
[tex]T_{5} = \frac{T_1 + T_2 + T_3 +T_4}{4}[/tex]
[tex]T_{5} = \frac{(T_1 + T_2) + T_3 +(T_4)}{4}[/tex]
Substitute [tex]2T_{3} = T_1 + T_2[/tex] and [tex]T_{4} = T_3[/tex]
[tex]T_{5} = \frac{2T_3 + T_3 +T_3}{4}[/tex]
[tex]T_{5} = \frac{4T_3}{4}[/tex]
[tex]T_{5} = \frac{(5-1)T_3}{5-1}[/tex]
Replace 5 with n
[tex]T_{n} = \frac{(n-1)T_3}{n-1}[/tex]
(n-1) will definitely cancel out (n-1); So, we're left with
[tex]T_{n} = T_3[/tex]
Hence,
[tex]T_{2020} = T_3[/tex]
Calculating [tex]T_3[/tex]
[tex]T_{3} = \frac{10 + 20}{2}[/tex]
[tex]T_{3} = \frac{30}{2}[/tex]
[tex]T_{3} = 15[/tex]
Recall that [tex]T_{2020} = T_3[/tex]
[tex]T_{2020} = 15[/tex]
Which statement is true of a market economy? A. It depends more on self-interest than a command economy does. B. It eliminates the problem of scarcity, unlike a command economy. C. It prioritizes the public good over personal freedom. D. It requires the approval of a regulatory body for innovation. E. It ensures that everyone will accumulate wealth.
The correct answer is A. It depends more on self-interest than a command economy does.
Explanation:
In the market economy, economical factors are mainly regulated by the actions of individuals and their interests, because these two factors determine supply and demand. For example, the supply of a specific product is determined by the manufactures of this product and their interest in obtaining profits. This does not occur in a command economy because, in this, the general interests of society prevail over self-interests, and economical factors are regulated by the government.
Answer:
The correct answer is A. A market economy depends more on self-interest than a command economy does.
Explanation:
A market economy is an economy where prices are determined by supply and demand in the market, at a price agreed by both buyers and sellers.
In a free-market system, the market and the whole economy are based primarily on the rational allocation of resources, that is, the type and quantity of goods on the market is determined by demand. The effort to achieve the highest possible profit forces the manufacturer to produce as efficiently as possible. This effort to maximize has two sides of the balance sheet: revenue works with the volume and pricing of the final product, but from the point of view of efficiency, on the contrary, it is about minimizing costs and especially not allowing depreciation of entire business cases as losses. The resulting product is then redistributed through the market.

Which statement best describes the arrival of P-waves and S-waves recorded at a station located closer to the epicenter of this same earthquake?
1. The time difference between the arrival of the first P-Wave and S-Wave would be less than 4 minutes.
2. The time difference between the arrival of the first P-Wave and S-Wave would be greater than 4 minutes.
3. P-Waves would be recorded, but no S-waves would arrive.
4. S-Waves would be recorded, but no P-Waves would arrive.
Please answer ASAP
Answer:
1. The time difference between the arrival of the first P-Wave and S-Wave would be less than 4 minutes.
Explanation:
S waves are slower than P waves, even if emitted at the same time. In this case, we can say that if a station is located close to the earthquake epicenter, the station would receive these waves quickly. The P wave would be received first, since it has a higher speed, the S wave would arrive soon. As you did not provide the times when each wave was emitted, we cannot accurately state the time when each wave would be perceived by the station. However, as the station is close to the earthquake, we can say that the time difference between P and S waves would be seconds, that is, less than 4 minutes.
Description of the P and S waves.
The P waves are those that are recorded first at the epicenter and they are first one to arrive the secondary or the S waves are those that don't travel through the liquids and they are second to arrive.
Thus the answer is the of the arrival and gap between both the waves is four minutes lesser.
Due to the fast movement of the P waves they are able to move through the solid and liquid at a higher velocity than the S waves and hence there is a time gap between them.They thus affect the arrival time on the seismograph.Hence the option One is correct.
