Answer:
Keplers Third Law
Step-by-step explanation:
Kepler's Third Law relates the period of an orbit to the radius of an orbit, if the orbit is circular, and to the semimajor axis if the orbit is elliptical.
Let's derive it for a circular orbit, assuming a mass m is orbiting a mass M, with r being the radius of the orbit.
ΣF = ma
GmM/r2 = mv2/r
Cancelling the m's and a factor of r gives:
GM/r = v2
We can bring in the period using:
v = 2πr / T
This gives GM/r = 4π2r2/T2
Re-arranging gives:
Kepler's Third Law: T2 = (4π2/GM) r3
For an system like the solar system, M is the mass of the Sun. So the constant in the brackets is the same for every planet, and we get the relationship that the period of the orbit is proportional to r3/2.
The same with satellites orbiting the Earth - in that case M is the mass of the Earth, but again the larger the orbit the larger the period.

B)y=−0.879x+43.293
C)y=1.988x−43.293
D)y=−0.879x−43.293
Answers
Answer:
The answer is option A y = −1.988x + 43.293
Step-by-step explanation:
I just took the test
The equation of the least squares regression line for the data set will be;
y = -1.988x + 43.293
Option A is true.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The table of data set is shown in figure.
Now, Let hours represent by x.
And, Tickets sold represent by y.
So, By the equation;
y = -1.988x + 43.293
Substitute x = 11;
y = -1.988 × 11 + 43.293
y = - 21.868 + 43.293
y = 21.62
y = 22
And, For x = 9;
y = -1.988 × 9 + 43.293
y = -17.892 + 43.293
y = 25.4
y = 24
Thus, Equation y = -1.988x + 43.293 shows the least-squares regression line for the data set.
So, The equation of the least squares regression line for the data set will be;
y = -1.988x + 43.293

(a - b)(a^2 + ab + b^2)
It should be solved using FOIL
Answers
Use the distributive property (of which the FOIL method is a special case):
(a - b) (a² + ab + b²)
= (a - b) a² + (a - b) ab + (a - b) b²
= (a³ - a²b) + (a²b - ab²) + (ab² - b³)
= a³ - b³
Alternatively, you can distribute the quadratic expression over each term in a - b :
(a - b) (a² + ab + b²)
= a (a² + ab + b²) - b (a² + ab + b²)
= (a³ + a²b + ab²) - (a²b + ab² + b³)
= a³ - b³

DESCRIBE how a power with a zero exponent (a^0) and a power with a negative exponent (a^−n) can be simplified.
Answers
Answer:
[tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]
[tex]a^{0}[/tex] = 1, where a ≠ 0
Step-by-step explanation:
To simplify the exponents, you must put it in positive value
Example:
The simplest form of [tex]2^{-3}[/tex] is to change the exponent from negative value to positive value.
You can do that by reciprocal the number, [tex]2^{-3}=(\frac{1}{2})^{3}[/tex]You can write it [tex]\frac{1}{2^{3}}[/tex], because 1 to any power equal 1That means if you want to simplify [tex]a^{-n}[/tex], reciprocal a and change the sign of the power from -n to n
The simplest form of [tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]
For any number, a (a ≠ 0), 1 × a = a, so, the reason that any number to the zero power is 1 because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, (1)
Example:
The value of [tex](5)^{0}[/tex] = 1, because it is the product of no numbers, so it is equal to the multiplicative identity (1)
That means [tex]a^{0}[/tex] = 1, where a ≠ 0
Very important note:
[tex](0)^{0}[/tex] is undefined value
