Find the radius of convergence, R, of the series. [infinity]â x^n
n = 1 5n â 1
Find the interval, I, of convergence of the series. (Enter your answer using interval notation.)
I = [â1, 1]

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

me

step-by-step explanation:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
