Ggiven a variable magnetic field b(r, t) = ηt4/s3ˆz [in cylindrical coordinates (s, φ, z)] where η is a constant, use ∇ × e = −∂b/∂t and ∇ · e = 0 directly to find e(r, t) in regions where the electron charge density rhoe = 0. assume that e is independent of z and φ with the boundary conditions es(s =

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

what chart am i supposed to follow?
