You used a telescope and other mathematics to discover that Jupiter is 5.20 au from the sun. Use the equation to find its orbital period. Round to the nearest tenth of a year.
Answer:
11.9 au
Step-by-step explanation:
The orbital period of Jupiter around the sun is 11.9 years.
Here, we have,
To solve this question, we need to understand the concept of Kelper's Third Law and how to use it.
we know that,
Kelper's Third Law:
Kelper's Third Law posits that the ratio between the square of the orbital period (T) as well as the average distance cube of a planet away from the Sun is constant for all planets circling the Sun.
T²/r³ = constant
Suppose, we make a reference to Earth, we have:
T_e²/r_e³ = T_j²/r_j³
Making the orbital period (T_j) of Jupiter as the subject, we have:
T_j = √T_e² * r_j³ /r_e³
where;
r_e = avg. distance from earth to sun = 1 au
so, calculating we get,
T_j = 11.9 years.

If a cube has a volume of 64 cubic inches, what is the area of the base of the cube?
Answer:
A = 16 cubic inches
Explanation:
If the volume is 64 cubic inches, that means each side (length, width, and height) are 4 inches each. This makes the area (l × w) is 16 cubic inches

Under a dilation centered at the origin, the vertex, (−2, 4), of a polygon is moved to the point (4, −8) . What is the scale factor of the dilation?
Answer:
-2
Step-by-step explanation:
I took the quiz.
The scale factor of the dilation is -2.
How does dilation works?Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation.
It's also called scaling of a figure, but due the involvement of coordinates, it involves a center of a dilation, which is like a pinned point which stays at same place after dilation.
It's like we enlarge or shorten the size of the figure (or keep it same, when scale factor = 1).
Given that Under a dilation centered at the origin, the vertex, (−2, 4), of a polygon is moved to the point (4, −8) .
Then the scale factor of the dilation
(-2k , 4k )= (4, −8)
Thus, -2k = 4
k = -2
Hence, the scale factor of the dilation is -2.

ax+3=23 if a=0 plz help
Answer:
x = [tex]\frac{23}{a}[/tex]
Step-by-step explanation:
Given equation is,
ax + 3 = 23
To solve this equation for the value of x isolate the variable 'x' on the one side of the equation.
Step 1,
Subtract 3 from both the sides of the equation.
ax + 3 - 3 = 23 - 3
ax = 20
Step 2,
Divide the equation by a,
[tex]\frac{ax}{a}=\frac{23}{a}[/tex]
x = [tex]\frac{23}{a}[/tex]
Therefore, x = [tex]\frac{23}{a}[/tex] will be the answer.

what is the solution for x in 12x-4=5x+24
Answer:
x = 4Step-by-step explanation:
12x - 4 = 5x + 24
First subtract 5x from both sides
That's
12x - 5x - 4 = 5x - 5x + 24
7x - 4 = 24
Add 4 to both sides
That's
7x - 4 + 4 = 24 + 4
7x = 28
Divide both sides by 7
We have the final answer as
x = 4Hope this helps you
Answer:4
Step-by-step explanation:First, add 4 to both sides of the equation. Then subtract 5x from both sides. Finally, divide both sides by 7.
