Explain in detail, how you solved the following problem: The first two terms of a sequence are 10 and 20. If each term after the second term is the average of all of the preceding terms, what is the 2020th term?
Answer:
[tex]T_{2020} = 15[/tex]
Explanation:
Given
[tex]T_1 = 10[/tex]
[tex]T_2 = 20[/tex]
Each term after the second term is the average of all of the preceding terms
Required:
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 process forms sedimentary rock in the rock cycle after sediments accumulate and combine?
Sediments undergo heat and pressure.
Sedimentary rock weathers and erodes,
Sediments compact and cement together.
Sedimentary rock experiences cooling and melting.
Answer:
Its the 3rd answer
Explanation:
Sediments compact and cement together forms sedimentary rock in the rock cycle after sediments accumulate and combine.
What is sedimentary rock?Sedimentary rocks form from the accumulation of sediments such as sand, silt, clay, and organic material. These sediments can accumulate in a variety of environments, such as on the bottom of oceans, lakes, and rivers, or in deserts. After the sediments accumulate, they undergo a process called diagenesis, which is the process by which sediments are transformed into sedimentary rock.
This process includes compaction, in which the sediments are squeezed together by the weight of overlying layers, and cementation, in which minerals precipitate out of solution and bind the sediment particles together. This process forms sedimentary rock like sandstone, limestone, and shale.

Compare and Explain Why ""day-time"" on the Moon is not the same as ""day-time"" on the Earth (how long and why the difference?)
Answer:
The reason "day-time" on the Moon is not the same as "day-time" on the Earth is that a day on the Moon is 27.32 Earth days or 655.72 hours long while a day on the Earth is 24 hours.
The differences are caused by the time it takes the moon to make a complete orbit or turn completely on its axis. It takes the moon 29 and half earth days with reference to the sun, and it takes the earth 24 hours to make a complete orbit on its axis with reference to the sun.
Explanation:
a) Day is approximately the period of time during which a satellite or celestial body completes one rotation around its axis.
b) The Moon, as we know it, is an astronomical body orbiting Earth as its only natural satellite. According to wikipedia.com, "it is the fifth-largest satellite in the Solar System, and by far the largest among planetary satellites relative to the size of the planet that it orbits."
c) The Earth is the third Solar planet and so far "the only astronomical object known to harbor human life," according to wikipedia.

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.

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.

WILL GIVE BRAINLIEST A travel agency is determining the prices for its Caribbean Cruise packages. The base price is $1500 per person. However, business is slow. To attract corporate clients, the travel agency reduces the price of each ticket by $5 for each person in the group. The larger the group, the less each person pays. If x represents the number of people in the group, what functions represent: 1) Base price per person f( x) 2) Total cost for group g( x) A. B. C. D.
Answer:
f(x) = 1500 -5x; g(x) = x(1500 -5x)
Explanation:
Subtracting $5 from the base price of $1500 for each person x in the group gives a price per person of ...
f(x) = 1500 -5x
The cost for the group is the cost per person (f(x)) times the number of people in the group (x).
g(x) = x·f(x)
g(x) = x(1500 -5x)
