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.

M is the midpoint of AB. Find the coordinates of B given A(3,8) and M(5,4).

Harlamova29_29 [7]

Answer: B(7,0)

Step-by-step explanation:

Since coordinate of A(3,8) and M(5,4), where M is the midpoint of AB.

Let the coordinate of B be (x,y)

Therefore, the distance AM is equal to distance MB.

Distance = sqrt{ (5 - 3)² + (4-8)² } =sqrt { (x-5)² + (y-4)²}

Comparing corresponding coordinates,

5-3 = x-5

x= 5+5-3 = 7

4-8 = y-4

y= 4-8+4= 0

Therefore, the coordinate of B is (7,0)

Si el área de una figura rectangular esta dada por A-bxh,¿cual es la siguiente expresiones representa el área de la puerta

stealth61 [152]

Respuesta:

3x² + 5x - 2

Explicación paso a paso:

Dado que :

Área del rectángulo, A = largo * ancho

Dimensión = 3x - 1; x + 2

Área = (3x - 1) * (x + 2)

Área = 3x² + 6x - x - 2

Área = 3x² + 5x - 2

Employee x earned $5250 in 3 weeks. at this rate how much will employee x earn in 8 weeks

iVinArrow [24]

Answer:

$14000

Step-by-step explanation:

Given parameters:

Amount earned by employee x = $5250

Time duration = 3weeks

Unknown:

Amount earned in 8 weeks = ?

Solution:

Let us first find the rate of employee x earning;

Rate = $\frac{Amount earned}{Time duration}$

Insert parameters;

Rate = $\frac{5250}{3}$ = $1750/week

So,

In 8 weeks;

Amount earned = rate x time duration

Amount earned = $1750/week x 8weeks

Amount earned = $14000
