$a_{1}=6561 and a_{n}=\frac{1}{3}a_{n-1}$

Step-by-step explanation:

$a_{3} = 729\\\\a_{4} = 243\\\\r = \frac{a_{4}}{a_{3}}\\\\r=\frac{243}{729}\\\\r=\frac{1}{3}$

Recursive rule: Next term is obtained by multiplying (1/3) wiht the previous term

$a_{n}=\frac{1}{3}*a_{n-1}$

$a_{3} = \frac{1}{3}*a_{2}\\\\\\729 = \frac{1}{3}*a_{2}\\\\\\729*3=a_{2}\\\\a_{2} = 2187\\\\\\$

$a_{2}=\frac{1}{3}*a_{1}\\\\\\2187=\frac{1}{3}*a_{1}\\\\\\2187*3=a_{1}\\\\a_{1}=6561$

Find the total surface area of the cone in the figure. ( use rr=3.14.)

nikitadnepr [17]

Answer:

Answer D

Step-by-step explanation:

The formula is $A = pi r(r+\sqrt{h^2+r^2})$ . We have our r (radius) and h (height), so plugging it all in would give us A = (3.14)(5 + sqrt(12^2)+(5^2). After computing this, you would get answer D, 282.6.

A person is listening to a 500 Hz tone sitting from a distance of 450 m from the sound source. What is the time interval between

iragen [17]

Answer:

So, the time interval between successive compression from the source is 0.002 seconds.

Step-by-step explanation:

Given that,

Frequency of the tone, f = 500 Hz

It is sitting at a distance of 450 m from the source of sound, d = 450 m

Let t is the time interval between successive compression from the source. We know that the relation between the frequency and the time period is :

$T=\dfrac{1}{f}T=\dfrac{1}{500}\\\\T = 0.002 s$

<h3>So, the time interval between successive compression from the source is 0.002 seconds.</h3>
