Function,d(r) = 0.034r , is used to convert Russian rubles in United States dollars, and function, e(d) = 0.76d , is used to con
Dahasolnce [82]
We have two functions, one which converts rubles to USD and one which converts USD to euros. If we want to convert from rubles to euros, we could just convert it to USD and then euroes.

2000₽ ⇒ USD
d(r)=0.034r\\d(2000)=0.034(2000)=68

$68 USD ⇒ €
e(d)=0.76d\\e(68)=0.76(68)=\boxed{51.68}

Extra: If you wanted, you could create a function to convert rubles into euroes.
Just substitute that 0.034r for d in e(d) = 0.76d and...e(r)=0.76(0.034r)=0.02584r

Classify each sequence as arithmetic, geometric, or neither by dragging it into the correct box.
garik1379 [7]

The sequences are classified, respectively, as:

Geometric, Arithmetic, Neither.

<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.

In the first sequence, we have that:

q = \frac{45}{15} = \frac{15}{5} = \frac{5}{\frac{5}{3}} = \frac{\frac{5}{3}}{\frac{5}{9}} = 3

Hence it is a geometric sequence.

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

In the second sequence, we have that:

d = -4 - 1 = 1 - 6 = 6 - 11 = 11 - 16 = -5

Hence it is an arithmetic sequence.

<h3>What about the third sequence?</h3>

\frac{4}{3} \neq \frac{3}{2}, 1 - \frac{1}{2} \neq 2 - 1

Hence it is neither arithmetic nor geometric.
