Ilya [14]

Answer:

x^6+3x^3+3+\dfrac{1}{x^3}

Step-by-step explanation:

We can use the pascal triangle to find the coefficients of the expasion of the cube. It holds that

(x^2 + \dfrac{1}{x})^3=(x^2)^3+3(x^2)^2\dfrac{1}{x}+3x^2(\dfrac{1}{x})^2+(\dfrac{1}{x})^3\\\\=x^6+3x^4\dfrac{1}{x}+3x^2\dfrac{1}{x^2}+\dfrac{1}{x^3}\\\\=x^6+3x^3+3+\dfrac{1}{x^3}

If you where born in 1620 and died in 1730 how old where u before u died?<br><br><br> pls help ;-;
Tema [17]

To make it simple, just subtract the age that you died to the age that you were born.

1730 - 1620 = 110

Which means that you would die at the age of 110 if you were born at 1620 and died on 1730.

Martin is interested in the effects of different kinds of instruction on videogame performance. Martin asks 30 college freshmen
777dan777 [17]

Answer:

Between - groups variance

Step-by-step explanation:

From the question we see that the college freshmen are assigned to one of the three given groups. This means that they are exposed to different experimental conditions and thus it means that the variation differs as a result of different experimental conditions between the groups.

Thus, these differences reflect between - group variance.
