So glad to see this homework post on IF. I am stuck on a calculus question, and I really need help.

The question:

A Pendulum swings through an arc of 120 cm (Swing #1)

With each further swing, the arc length is reduced by 15 %

a) State the growth factor

b) calculate the length of the arc in Swing # 4

I think I'm supposed to use this formula:

Tn = ar^n-1

I just dont get what to plug where. Tn is the term number, a would be the first term, I think the percentage would go in for n. This is dead confusing :\

You are on the right track! Tn is the term number, a is the first term, n is the difference which in this case is 15%.

^^ Thanks Komal, so I believe that the term number would be the amount of swings. And a would probably be where the 120 cm goes. I'll try and solve this out...

Ok I got 18 as an answer, did something totally wrong, cause the answer for the growth rate is supposed to be 0.85. I think 15% is supposed to go in for r, which is the ratio.

Ok I just dont get how to do this, I keep multiplying 0.15 by 120, and I keep arriving at 18:\

Just now I saw this question.
a) The arc length in a swing is 85% of i.e. 0.85 times the arc length in the previous swing.
Therefore the arc lengths are in geometric sequence with first term a = 120 cm and common ratio r = 0.85
Growth factor = 0.85

b) Tn = a r^(n-1)
T4 = a * r^3
= 120 * 0.85^3
= 73.7 cm

In English language, India is officially known as the Republic of India. The government in India is in the form of parliamentary system of democracy. The government is regulated by the constitution of India which came into effect on 26th January, 1950 (the replublic day of India).

The government is composed of three branches:

Executive

Legislature

Judiciary

Executive: The President of India is the head of state. However, in reality, the president's powers are highly limited. Most of executive powers are with the Prime Minister. The executive branch of the Indian government consists of the president, the vice-president, and the council of ministers. The council of ministers is headed by the prime minister.

Legislature: The legislature of India comprises the upper house called the Rajya Sabha and the lower house called the Lok Sabha. The members of Rajya Sabha are elected directly by the eisting ministers. The members of Lok Sabha are elected based on public voting. In India there are different political parties. Usually the party which wins most of seats through public voting forms the government. However, there are times when a single party does not win enough seats to form the government alone. In that case, more than one party form an alliance and form the government together.

Judiciary: The judiciary in India consists of the Supreme Court, High courts and trial courts. The courts interpret the constitution and prnounce judgements. There is one Supreme court, which is headed by the chief justice of India. Supreme court is the most powerful of all the courts.

Let me know if you need any further details.
