I do not see your map. However a major advantage for the North in the Civil War was that the North had a lot more rail transportation, even before Sherman went through.

what about it ?
y = -2 x -16 ???? you do not say what you want done

I agree with you.

Well, it did not make slavery legal really in Massachusetts for example, but it said the owner could come get him which pretty much amounts to the same thing.

I guess, sort of.

2 ln (x-6) well I think x better be greater than 6

(2x-1)/(x^2-1) = a/(x+1) + b/(x-1) 2x-1 = ax-a + bx + b 2 = a+b -1 = -a+b -----------add 1 = 2 b b = 1/2 a = 2-b = 3/2 so (3/2) / (x+1) + (1/2)/(x-1)

let's put the center of each at 0,0 to make it easy ellipse x^2/a^2 + y^2/b^2 = 1 we could make a and b the same, but that would be a circle and too easy so lets make a = 2 and b = 1 x^2/4+y^2/1 = 1 then major axis along x = 2a = 4 vertex at -2,0 and + 2,0 (also at 0,1 and...

yes, but what are you going to use 0.454545.... of a CD for?

well, start by thinking what is a 50% raise in all cases, original = 100 now 50% = 50 so now 150 instead of 100 now 100% = 100 so now 200 instead of 100 now 150% so now 250 instead of 100 In other words 150% raise is 150% more than original or 250% OF original. Two and a half ...

omega top = 5 * 2 pi radians/2.78 s = 11.3 radians/s omega = alpha t 11.3 = alpha (17.9) alpha = .631 radians/s^2 but is you want linear radial acceleration only that is Ac = v^2/r =omega^2 r = 11.3^2 * .0713 = 9.10 m/s^2 (close to 1 g :)

rate is 40 person hours/ room (40 p hr/ r)/(4p) = 10 hr/room

trig
whew, good !

trig
you could say that r = -6 and theta = pi/2 but that is no good, r must be +

trig
x = 0 y = -6 that is 6 units directly below the origin so r = 6 = sqrt(0^2+6^2) you are three quarters of the way around to two pi

trig
Hey, sketch this stuff on a rough graph.

trig
r = 6 straight down = (3/4)(2 pi) = 3 pi/2 = 1.5 pi

No, I am not going to Google Young's modulus of steel for you, E L = 0.6 m r = 0.0025 m A = pi (.0025)^2 delta L/L = 2.5(9.81)/(E A) delta L = 0.6*2.5*9.81/(E*pi*.0025^2)

r^2 = 25 +25*3 = 100 so r = 10 tan theta = sqrt3 in quadrant III 60 degrees below x axis pi + pi/3 = 4 pi/3 you are in third quadrant because x and y are negative
