Answer:

x = 4 sqrt(3)

Step-by-step explanation:

x is not to be confused by the mark on the right angle -- X

The function is the cosine of Y which is 30 degrees.

The cosine of 30o is sqrt(3)/2

cos(30) = adjacent side / hypotenuse = sqrt(3) / 2

The adjacent side is 6

cos(30) = 6/ x = sqrt(3) / 2

6/x = sqrt(3) / 2                      Cross multiply

x * sqrt(3) = 6 * 2

x * sqrt(3)  = 12                       divide by sqrt(3)

x = 12 / sqrt(3)                        Multiply top and bottom by sqrt(3)

x = 12* sqrt(3) / sqrt(3) * sqrt(3)

x = 12 sqrt(3)/ 3                      Divide by 3

x = 4 sqrt(3)

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.

A chemist heats up several unknown substances to determine their boiling point. Use the table to determine whether the sequence
Varvara68 [4.7K]

Since the <u>difference between consecutive terms is not constant</u>, the sequence is not arithmetic.

In an arithmetic sequence, the <u>difference between consecutive terms is constant</u>, called common difference d.

A recursive formula is given by:

a_{n+1} = a_{n} + d

In which a_1 is the first term.

In this problem:

  • The terms are: 100, 135, 149, 165, 188.
  • 135 - 100 = 35, 149 - 135 = 14, that is, the differences are not constant, so this is not an arithmetic sequence.
