Recall that for |<em>x</em>| < 1, we have

Replace <em>x</em> with 2<em>x</em>, multiply 4, and call this function <em>f</em> :

Take the derivative:

By the ratio test, the series converges for

or |<em>x</em>| < 1/2, so the radius of convergence is 1/2.
It’d be B, -2
You move right one space and then down two spaces
I think the answer is 2x^3+10x^2-2x-10
Answer:
the answer is c
Step-by-step explanation:
Since jane weighs 126 and is gaining 3 pounds per month that would make the part of the equation that is 126+3m and since Cynthia weighs 134 and is gaining 2 pounds every month that is what makes the 134+2m part of the equation. And since the equation is 134+2m=126+3m then the goal is to find how many months it would take for their weights' to be equal. Sorry that my explaining skills are terrible hopefully I helped a little.
