S = 1 / g t ² π, solve for t

Finger [1]

$s = \frac{1}{g {t}^{2}\pi }$

multiply through by

$g {t}^{2} \pi$

$s \times g {t}^{2} \pi = \frac{1}{g {t}^{2} \pi} \times g {t}^{2} \pi$

$sg {t}^{2} \pi = 1$

dividing through by

sgπ

${t}^{2} = \frac{1}{sg\pi}$

$t = \sqrt{ \frac{1}{sg\pi} }$

The speed of light is approximately 299,000,000 meters per second.

jek_recluse [69]

Answer:

2.99 x 10⁸ meters per second

Step-by-step explanation:

Scientific notation (also called "Standard form") is written in the form of $a \times 10^n$ , where $1\leq a < 10$ and $n$ is any positive or negative whole number.

To <u>convert</u> a number into <u>scientific notation</u>, move the decimal point to the left or right until there is <u>one digit before the decimal point.</u>

The number of times you have moved the decimal point is the power of 10 ( $n$ ).

If the decimal point has moved to the <u>left</u>, the power is <u>positive</u>.

If the decimal point has moved to the <u>right</u>, the power is <u>negative</u>.

<u>To convert the given number to scientific notation</u>

The decimal point for the given number 299000000 is after the last zero:

⇒ 299000000.

Move the decimal point 8 places to the left:

⇒ 2.99000000

Get rid of the redundant zeros:

⇒ 2.99

Multiply by 10 to the power of the number of decimal places moved:

⇒ 2.99 x 10⁸

Therefore, the speed of light using scientific notation is:

2.99 x 10⁸ meters per second

Naysha listens to the radio for five-sixths of an hour each day. which expressions represent the time naysha spends listening to

Yakvenalex [24]

The time Natasha listens to the radio can be represented as 7 times five sixths, 35/6 or 5/6 + 5/6 + 5/6 + 5/6 + 5/6.

<h3>How to find out the time Natasha listens to the radio in one week?</h3>

Time per day: 5/6 of an hour
Time per week: 5/6 + 5/6 + 5/6 + 5/6 + 5/6 = 35/6

or 5/6 x 7 = 35/6

<h3>How to represent this?</h3>

There are three options:

5/6 + 5/6 + 5/6 + 5/6 + 5/6
35/6
5/6 x 7
