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.

You begin painting your house with 10 gallons of paint you purchased at the hardware store. Each gallon of paint covers 400
square feet of surface area. If g is the gallons of paint used for painting x square feet, which type of model would best describe the
relationship between g and x?
A)
linear
B)
radical
quadratic
D)
exponential
Answer:
A) linear
Step-by-step explanation:
Let the gallons of paint be represented by g, and the area by x.
Each gallon of paint covers 400 square feet of surface area.
⇒ x = 400g
So that; when g = 1,
x = 400 square feet
when g = 5,
x = 400 x 5
= 2000 square feet
when g = 10,
x = 400 x 10
= 4000 square feet
The relationship between the variables is linear because g and x increases at a constant rate.

Answer:
The Sidewalk is 16 yards^3
Step-by-step explanation:
To find the this answer its quite simple!
Anytime there's an area problem you would have to multiply to numbers to get the area
in this case 16 is the answer because when you multiply 16 * 16 you get the total area of 256 yards. hope this was understand able!
High Hopes^^

CAN SOMEONE PLS HELP WITH THIS!!
Answer:
4/5
Step-by-step explanation:
{(2/5) / (1/2)} ×1
= (2/5)÷(1/2)
= 2/5×2/1
= 4/5
Answer:
4/5
Step-by-step explanation:
Because if it can eat 2/5's in 1/2 hours, then if it eats for 1 whole hour or 2/2's it will be able to eat 4/5's of it's own body weight.
Just imagine that one half hour is 1 and if you add two half hours together it makes one complete hour or 2/2. So just multiply it by 2 cause it was eating for two half hours.
[tex]\frac{2}{5} * 1=2/5\\\frac{2}{5} *2=4/5[/tex]
Graph the image of the given triangle after the transformation with the rule
(x, y) —> (-x,y)
Answer:
The coordinates of image are : (-3,4) , (-8,2) and (-4,7)
Step-by-step explanation:
The rule is given as (x, y) —> (-x,y)
The coordinates of the triangle are : (3,4) , (8,2) and (4,7)
The coordinates of the image of the triangle will be : (-3,4) , (-8,2) and (-4,7)
Graphing the coordinates of image and connect the points to get the image of the triangle as attached below;
You will notice the rule of the transformation is a reflection along the y-axis.

Plz Help will give major points and brainliest.
Answer:
see below
Step-by-step explanation:
a) The unknown is the price of a large pizza
b) Each pizza cost is positive,
c) The the price of a pizza be p,
so the price of one pizza is p
d) The expression is
6 pizzas minus 3 dollar off each pizza
6p -3p
e) Set this equal to the total cost
6p -3p= 38.94
f) Combine like terms
3p = 38.94
Divide each side by p
3p/3 = 38.94/3
p = 12.98
The price of each pizza before discount is 12.98

(-oo, 15)Since Neil Armstrong was the first person to walk on the. moon, the contrapositive is
Answer:
If nobody walked on the moon, then Neil Armstrong didn't
Step-by-step explanation:
The contrapositive flips the sign of "Neil Armstrong" and the "moon," and also switches their position, so you will switch the hypothesis and conclusion as well
Determine the value of y, if x is-6.
y= |x|+ 6
Answer:
Answer:
y = 12
Step-by-step explanation:
The two bars between x mean absolute value, so all negatives turn into positives because absolute value just means the total distance from zero.
y = |x| +6
y = |-6|+6
y = 6+6
y = 12
Have an amazing day!!!! C:
½(10x - 18) - 13x = -2x + 7 - 6x
I linked a photo
Answer:
no solutions
Step-by-step explanation:
½(10x - 18) - 13x = -2x + 7 - 6x
Distribute
5x -9 -13x = -2x +7 -6x
Combine like terms
-8x -9 = -8x+7
Add 8x to each side
-8x -9 +8x = -8x+7+9x
-9 = 7
This is never true so there are no solutions

Answer:
h=−6.28r2+s/6.28r
Step-by-step explanation:
Step 1: Flip the equation.
6.28hr+6.28r2=s
Step 2: Add -6.28r^2 to both sides.
6.28hr+6.28r2+−6.28r2=s+−6.28r2
6.28hr=−6.28r2+s
Step 3: Divide both sides by 6.28r.
6.28hr/6.28r=−6.28r2+s/6.28r
h=−6.28r2+s/6.28r
