My assignment: Arithmetic series

Junior put 10 pesos in his piggy bank yesterday. If he is planning to add 3 pesos in every previous amount that he saved.

Answer the following questions.

A. How much money will he have after 30 days?

B. How much money did he put in his piggy bank on the 3rd day after today?

C. After how many days did he reach a total savings of 2,250 pesos?

To solve these questions, we can use the concept of an arithmetic series. In an arithmetic series, each term is obtained by adding a constant difference to the previous term.

Let's find the values for each question:

A. How much money will he have after 30 days?
To find the total amount of money after 30 days, we can use the formula for the sum of an arithmetic series:

Sn = (n/2) * (2a + (n-1)d)

Where:
Sn = sum of the series
n = number of terms
a = first term
d = common difference

In this case, the first term (a) is 10 pesos, the common difference (d) is 3 pesos, and the number of terms is 30 (since he saves money for 30 days).

Using the formula:
S30 = (30/2) * (2*10 + (30-1)*3)
= 15 * (20 + 29*3)
= 15 * (20 + 87)
= 15 * 107
= 1,605 pesos

Therefore, Junior will have 1,605 pesos after 30 days.

B. How much money did he put in his piggy bank on the 3rd day after today?
To find the amount of money on the 3rd day, we can use the formula for the nth term of an arithmetic series:

an = a + (n-1)d

Where:
an = nth term
a = first term
d = common difference

In this case, the first term (a) is 10 pesos, the common difference (d) is 3 pesos, and the value of n is 3 (since we are interested in the 3rd day).

Using the formula:
a3 = 10 + (3-1)*3
= 10 + 2*3
= 10 + 6
= 16 pesos

Therefore, Junior put 16 pesos in his piggy bank on the 3rd day after today.

C. After how many days did he reach a total savings of 2,250 pesos?
To find the number of days required to reach a total savings of 2,250 pesos, we need to rearrange the formula for the sum of an arithmetic series:

Sn = (n/2) * (2a + (n-1)d)

In this case, the first term (a) is 10 pesos, the common difference (d) is 3 pesos, and the sum (Sn) is 2,250 pesos.

We can rewrite the formula as a quadratic equation: n^2 + 29n - 450 = 0

Solving this equation, we find that n = 15 or n = -30. Since the number of days cannot be negative, the answer is 15.

Therefore, Junior reached a total savings of 2,250 pesos after 15 days.

I'm confused,

In question A, Junior save 1,605 pesos after 30 days

While in question C, Junior reach a higher amount (2,250 pesos) in only 15 days?

How?

How?

Apologies for the confusion caused. Let's reevaluate the calculations.

A. How much money will he have after 30 days?
We can use the formula for the sum of an arithmetic series:

Sn = (n/2) * (2a + (n-1)d)

Using:
n = 30 (number of terms)
a = 10 (first term)
d = 3 (common difference)

S30 = (30/2) * (2*10 + (30-1)*3)
= 15 * (20 + 29*3)
= 15 * (20 + 87)
= 15 * 107
= 1605 pesos

Therefore, Junior will have 1,605 pesos after 30 days.

C. After how many days did he reach a total savings of 2,250 pesos?
Using the same formula, now we know the desired sum (Sn) is 2,250 pesos.

2250 = (n/2) * (2*10 + (n-1)*3)
4500 = n * (20 + 3n - 3)
4500 = 23n^2 - 23n + 40
23n^2 - 23n - 4460 = 0

Using the quadratic formula, n = (-b ± √(b^2 - 4ac)) / (2a), where a = 23, b = -23, and c = -4460.

n = (-(-23) ± √((-23)^2 - 4*23*(-4460))) / (2*23)
n = (23 ± √(529 + 411560)) / 46
n = (23 ± √412089) / 46

Since the number of days cannot be negative, we take the positive value:
n = (23 + √412089) / 46
n ≈ 31.94

Therefore, it would take approximately 32 days for Junior to reach a total savings of 2,250 pesos.

To solve this equation, we can use factoring or the quadratic formula. Factoring the equation (n + 45)(n - 10) = 0, we get two possible solutions: n = -45 and n = 10. Since the number of days cannot be negative, the answer is 10.

Therefore, it would take 10 days for Junior to reach a total savings of 2,250 pesos.

Historiography is the art of writing and theory of historical writing, originating from the greek words historia and graphier. It gain prominence in the early 1900s with recent developments like Micheal Foucault new historicism broadening historical interpretation.

Ang historiography ay ang sining ng pagsusulat at teorya ng pagsusulat ng kasaysayan, na nagmumula sa mga salitang Griyego na "historia" at "graphier." Ito ay umangat sa simula ng 1900s kasama ang mga kamakailang pag-unlad tulad ng new historicism ni Michael Foucault na nagpapalawak ng interpretasyon ng kasaysayan.

Ang historiography ay naglalayong pag-aralan ang proseso ng pagsusulat ng kasaysayan, kung paano ito nabuo, at kung paano ito naaapektuhan ng mga pananaw, kaisipan, at mga salik ng lipunan. Ito ay nagpapahalaga sa pag-aaral ng iba't ibang interpretasyon at perspektibo, at kung paano ang mga ito ay maaaring magbago at mag-evolve sa panahon.

Sa pamamagitan ng historiography, mas nauunawaan natin ang kahalagahan ng konteksto, ang impluwensiya ng mga paniniwala at kulturang panlipunan sa pagsusulat ng kasaysayan, at ang mga limitasyon at bias na maaaring umiral sa mga akda.

Ang paglago ng historiography sa mga nakaraang dekada ay nagdulot ng mga malawakang pagbabago at mga bagong pamamaraan sa pagsusulat ng kasaysayan. Ito ay nagbukas ng mga posibilidad para sa mas malalim na pagsusuri at interpretasyon ng mga pangyayari at mga personalidad na may kinalaman sa kasaysayan.

Sa kabuuan, ang historiography ay mahalagang bahagi ng pag-unawa natin sa kasaysayan at nagbibigay daan sa atin upang maunawaan ang iba't ibang perspektibo at konteksto na bumubuo ng ating nakaraan.

After the Philippines regained its independence in 1946, the newly established Philippines republic had to confront several problems. Aside from the rehabilitation of the country, the newly established government had to face the problems concerning national unity and national identity. In this light, the country was in need of history that will reflect the characters of the people and will serve as a unifying factor of the country.
