Answer:

Option (B).

Step-by-step explanation:

Option (a). {(1, 2), (3, 4), (4, 5), (6, 7)}

Since in every ordered pair value of x corresponds a distinct value of y.

The given ordered pairs represent one-to-one function.

Option (b). {(0, 3), (1, 5), (3, 9), (1, 13)}

In the ordered pairs (1, 5) and (1, 13) value of x correspond to the two different values of y.

Therefore, its not a function.

Option (c). {(-2, 2), (-3, 3), (-4, -4), (-5, -5)}

For every value of x there is distinct value of y.

Therefore, given set of ordered pairs represent a one to one function.

Option (d). {(1, 2), (2, 2), (3, 5), (4, 8)}

Ordered pairs represent a function.

Option (B), will be the answer.

1.2,3,7.5,18.75, which formula can be used to describe the sequence

elena-14-01-66 [18.8K]

Answer:

$a_{n}=1.2 \times(2.5)^{n-1}$

Step-by-step explanation:

If we observe the given sequence, we find that the ratio of two consecutive terms is the same. i.e.

$\frac{3}{1.2}=2.5\\\\\frac{7.5}{3}=2.5\\\\ \frac{18.75}{7.5}=2.5$

Such a sequence in which the ratio of consecutive terms remain the same is know as Geometric Sequence. Following formula is used to represent a Geometric Sequence:

$a_{n}=a_{1}\times(r)^{n-1}$

Here:

$a_{n}$ is the general term. Using the value of n =1,2,3 ... will give us the term of the sequence.

$a_{1}$ is the first term which is 1.2 in this case.

r represents the common ratio which is 2.5.

Using these values we get:

$a_{n}=1.2 \times(2.5)^{n-1}$

This formula can be used to represent the given sequence.

yang company sold merchandise for $4,000. the event is subject to a state sales tax of 9%. based on this information, yang would

Mademuasel [1]

Sales revenue will be recorded at $4,000 and yang Yang would be required to Recognize sales tax liability of $360.

What is sales revenue?

The terms revenue and sales revenue are sometimes used synonymously.
However, the concept of revenue includes income derived from sources other than those directly connected to the primary business, such as interest on savings or money distributed as dividends.
Revenue comprises income derived from the sale of goods and services. The classification of this is "non-operating income."

Sales = $4,000

State sales tax rate = 9%

State sales tax = Sales x State sales tax rate

= 4,000 x 9%

= $360

Sales revenue will be recorded at $4,000 and sales revenue is not affected by the sales tax amount.

Hence, Yang would be required to Recognize sales tax liability of $360.
