Find the values of x for which the series converges. (Enter your answer using interval notation.) [infinity] (−5)nxn n = 1 Find the sum of the series for those values of x.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
