determine whether the series is convergent or divergent using either the integral test or the comparison test:

1) summation notation symbol (with n=1 on bottom and infinity on top) of (ne)^-n

2) summation notation symbol (with n=1 on bottom and infinity on top) of ((cos^2)n)/(n^2 + 1)

3) summation notation symbol (with n=1 on bottom and infinity on top) of 1/ sqrt of (n^2 + 1)

show work/explanation so i know how u got the answer..thanks

Use the integral test to determine whether the series is convergent or divergent:

1) summation notation symbol (with n=1 on bottom and infinity on top) of 1/ 4th square root of n

2) summation notation symbol (with n=1 on bottom and infinity on top) of 1/n^4

show steps plz

Sketch the region and find its area (if the area is finite)

S = { (x,y) / x > or equal to -2, 0 < or equal to y < or equal to e^(-x/2) }

Use the Comparison Theorem to determine whether the integral is divergent or convergent.

Find the values of "x" for which the series converges. Find the sum of the series for those values of "x".

1) summation notation symbol (with n=1 on bottom and infinity on top) of x^n/3^n

2) summation notation symbol (with n=0 on bottom and infinity on top) of cos^nx/2^n

show steps so i know how u did it..thanks

A machinist is required to manufacture a circular metal disk with area 1700 cm2.

(a) What radius produces such a disk?
I found the answer to be 23.26 cm.

(b) If the machinist is allowed an error tolerance of ±6 cm2 in the area of the disk, how close to the ideal radius in part (a) must the machinist control the radius?

what's the answer to b? thanks so much!

3 men stay in a hotel and the cost is £10 per night - total £30.

they settle the bill the next day paying £10 each again total £30. they leave the hotel and the owner likes the men so he gives the porter £5 and tells him to run after the men and give them the £5. the porter is slightly dishonest and keeps £2 for himself and gives each man £1 back.

now the men have paid £9 (£27) and the porter has £2 so the total is now £29 - where is the other £1.

ok so im doing linears, and like..how do u graph the equation?
i kno therez no graph here, so it would be hard to explain, but can u tell me the steps?
graphing:

y = x - 2
y = -x
y = 4x-1
y = -x+3

all of them seperately. if u want to explain one..thats fine too.
thanks
