The orbital period, P, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula P

mixas84 [53]

Answer:

9.54731702 astronomical units

Step-by-step explanation:

$P=a^{\frac{3}{2} }$

Substitute this value in the equation above:

$29.5=a^{\frac{3}{2} }$

⇒ $(29.5)^{\frac{3}{2} } =a$

⇒ $a=9.54731702$ $astronomical$ $units$

Hence, its distance from the sun is 9.54731702 astronomical units.

Kyle’s bank statement shows a balance of –$18.50. Which describes the magnitude, or size, of the debt in dollars?

oksano4ka [1.4K]

Answer:

C. $18.50.

Step-by-step explanation:

We have been given that Kyle’s bank statement shows a balance of –$18.50. We are asked to determine the magnitude, or size, of the debt in dollars.

We know that the magnitude of a negative number is absolute value of negative number.

$\text{Magnitude of debt in dollars}=|-\$18.50|$

Since absolute value of a negative number is opposite of the number.

$\text{Magnitude of debt in dollars}=-(-\$18.50)=\$18.50$

Therefore, option C is the correct choice.
