Find a power series representation for the function. (Give your power series representation centered at x = 0.)f(x) = x3x2 + 1f(

makkiz [27]

I suppose you mean

$f(x)=\dfrac{x^3}{x^2+1}$

Recall that for $|x|$ , we have

$\dfrac1{1-x}=\displaystyle\sum_{n=0}^\infty x^n$

Then

$\dfrac1{1+x^2}=\dfrac1{1-(-x^2)}=\displaystyle\sum_{n=0}^\infty(-x^2)^n=\sum_{n=0}^\infty(-1)^nx^{2n}$

which is valid for $|-x^2|=|x|^2$ , or more simply $|x|$ .

Finally,

$f(x)=\displaystyle\frac{x^3}{x^2+1}=\sum_{n=0}^\infty(-1)^nx^{2n+3}$

Inscribed angles. need answers asap , thank u!

Sever21 [200]

Answer:

40°

Step-by-step explanation:

The circumference of a circle is equal to 360°

The arc AB is 180°, the arc AC is given as 100° so the arc CB is 80° and since <A is an inscribed angle it is equal to the half of the arc it sees

80 ÷ 2 = 40
