From my website, I have an online Kepler's Third Law calculator.
The formula is G · m · t² = 4 · π² · r³
I had to solve I have the formula solved for 'r', 't' and 'm' and I made a graphic of all three formulas. (see attached).
Anyway, since the formula is <span>G · m · t² = 4 · π² · r³ then we can solve for 'r'
</span>
<span>r³ = (G · m · t²) / (4 · π²) and therefore
r = </span><span>cube root [(G · m · t²) / (4 · π²)]

Answer:
<h2>The graph of y = 2x² + 5x + 9 has zero x-intercepts.</h2>
Step-by-step explanation:
x-intercepts are for y = 0.
Put y = 0 to the equation y = 2x² + 5x + 9:
2x² + 5x + 9 = 0
Calculate the discriminant of quadratic equation ax² + bx + c = 0:
Δ = b² - 4ac
if Δ < 0, then an equation has no solution
if Δ = 0, then an equation has one solution
if Δ > 0, then an equation has two solution.
2x² + 5x + 9 = 0
a = 2, b = 5, c = 9
Δ = 5² - 4(2)(9) = 25 - 72 = -47 < 0 - no solution
Answer:
11/20
Step-by-step explanation:
To be able to find the fraction of the cake that Jake ate if you know that he ate 55% of it, you have to turn the 55% into a fraction. To do this, first you have to divide the percent by 100:
55/100
Then, you have to simplify the fraction. In this case, you can do it by dividing by 5:
11/20
According to this, the fraction of the cake that Jake ate is 11/20.
Answer: A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. ... Examples of single terms: 3x is a single term. The "3" is a coefficient. The "x" is the variable.
Step-by-step explanation:
13x-8+7x+4+3x
Combine like terms
23x-4
It can only be simplified. Without an equal sign (=), x cannot be found.
