The recursive geometric sequence that models this situation is:

f(n) = 0.9f(n-1)

f(1) = 90000

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

It can be represented by a recursive sequence as follows:

f(n) = qf(n-1)

With f(1) as the first term.

In this problem, the sequence is: 90.000: 81,000; 72,900; 65,610, hence:

q = \frac{65610}{72900} = \cdots = \frac{81000}{90000} = 0.9

f(1) = 90000

Hence:

f(n) = 0.9f(n-1)

f(1) = 90000

ABCD is a rectangle. if AC = 3y/5 anf BD= 3(y-4), find the length of each diagonal
Digiron [165]
Remember please that Diagonals of a Rectangle are equal to each other:<span> 3y/5 = 3(y-4)
So 
</span><span>3y = 15(y-4)
3y = 15y - 60
60 = 12y
y = 5 Diagonals are both 3 units
With that you will be able to know which is the answer from your options</span>

Determine whether the sequence converges or diverges. If it converges, find the limit. (If an answer does not exist, enter DNE.)
In-s [12.5K]

Answer:

The sequence diverges.

Step-by-step explanation:

A sequence a_{n} converges when \lim_{n \rightarrow \infty} a_{n} is a real number.

In this question, the sequence given is:

a_{n} = 4n\cos{(7n\pi)}

The cosine is always going to be between -1 and 1, so for the convergence of the sequence, we look it as: a_{n} = 4n. So

\lim_{n \rightarrow \infty} a_{n} = \lim_{n \rightarrow \infty} 4n = \infty

Since the limit is not a real number, the sequence diverges.
