\qquad\qquad\huge\underline{{\sf Answer}}♨

Circumference of circle is :

\qquad \tt  \dashrightarrow \:\pi d

where,

  • d = diameter of circle

\qquad \sf  \dashrightarrow \:c = 20 \pi \:  \: cm

Now, let's plug approximate value of pi

\qquad \sf  \dashrightarrow \:c = 20  \times 3.14\:  \:

\qquad \sf  \dashrightarrow \:c = 62.8 \:  \: cm

Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $1
Olenka [21]

Answer:

\$16,826,000.

Step-by-step explanation:

We have been given that Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $15,342,000 the third quarter, and a loss of $48,037,000 for the fourth quarter.

To find the net profit for year, we will subtract the loss in the 4th quarter from the sum of profit in 3 quarters as:

\text{Net profit for the year}=\$28,951,000+\$20,570,000+\$15,342,000-\$48,037,000

\text{Net profit for the year}=\$64,863,000-\$48,037,000

\text{Net profit for the year}=\$16,826,000

Therefore, the net profit for the year was \$16,826,000.

Solve (1/81)^x*1/243=(1/9)^−3−1 by rewriting each side with a common base.
elena55 [62]

Answer:

x=(243)log_{\frac{1}{81}}[(\frac{1}{81})-1]

Step-by-step explanation:

you have the following formula:

(\frac{1}{81})^{\frac{x}{243}}=(\frac{1}{9})^{-3}-1

To solve this equation you use the following properties:

log_aa^x=x

Thne, by using this propwerty in the equation (1) you obtain for x

log_{(\frac{1}{81})}(\frac{1}{81})^{\frac{x}{243}}=log_{\frac{1}{81}}[(\frac{1}{81})-1]\\\\\frac{x}{243}=log_{\frac{1}{81}}[(\frac{1}{81})-1]\\\\x=(243)log_{\frac{1}{81}}[(\frac{1}{81})-1]
