Answer:

Step-by-step explanation:

M is the midpoint of AB. That means that 2 binomials are equal.

4n - 40 = 7* (-2n + 2) Remove the brackets

4n - 40 = - 14n + 14 Add 14n to both sides

4n+14n - 40 = -14n+14n + 14 Combine

18n - 40 = 14 Add 40 to both sides

18n = 14 + 40 Combine

18n = 54 Divide by 18

18n/18 = 54/18 Combine

n = 3

babunello [35]

Answer:

$\mathbf{g(x) = \sum \limits^{\infty}_{n=0} (-1 + (\dfrac{-1}{6})^n)x^n }$

and the interval of the convergence is (-1, 1)

Step-by-step explanation:

To find a power series for the function, centered at c.

$g(x) = \dfrac{7x}{x^2 +5x-6} ,\ c = 0$

If we factorize the denominator, we have:

$g(x) = \dfrac{7x}{(x +6)(x-1)}$

$g(x)= \dfrac{1}{x-1}+\dfrac{6}{x+6}$

Thus;

$g(x)= \dfrac{-1}{1-x}+\dfrac{1}{1+\dfrac{x}{6}}$

$g(x)= \dfrac{-1}{1-x}+\dfrac{1}{1-(-\dfrac{x}{6})}$

$g(x) = - \sum \limits^{\infty}_{n=0} x^n + \sum \limits^{\infty}_{n=0} x^n(\dfrac{-x}{6})^n \ \ if \ \ |x| < 1 \ \ and \ \ |\dfrac{x}{6}< 1$

$g(x) = \sum \limits^{\infty}_{n=0} (-1 + (\dfrac{-1}{6})^n)x^n , \ if |x|$

$\mathbf{g(x) = \sum \limits^{\infty}_{n=0} (-1 + (\dfrac{-1}{6})^n)x^n }$

and the interval of the convergence is (-1, 1)
