Note that Walmart's fiscal year starts the first week of
February. This means that when analyzing the data, week 26 is
actually week 30 (26+4 weeks for January) in 2002 or the end of
July 2002. Also, week 52 is actually week 4 (52+4 weeks for January
2002 minus 52 weeks for 2002) in 2003 or the end of January 2003.
As an example, the spike in sales(revenue) at week 75 occurs in
week 27 (75+4 weeks for January 2002...

1. Identify spikes(outliers) in the data where extreme (high or
low) sales values occur and correlate these spikes with actual...
What is the magnitude and direction of an electric field if it
exerts a downward force of 10-6N on a charge of -5μC?
Could you please explain how to do this question? Thank you
Stresses at a point are: 60 MPa in the x-direction, 80 MPa in
the y-direction and no shear stress in this reference x-y plane.
Note that these are already the principal stresses and the
reference plane x-y is the principal plane. What are the stresses
at 45o clockwise from the principal planes? Show them on
a properly-oriented element. Mohr’c cirle is to be used and no
equations will be accepted.
A) Find the directional derivative of the function at the given
point in the direction of vector v. f(x, y) = 5 + 6x√y, (5, 4), v =

A point on a circle with a diameter of 10m starts at
an upright position P at (0,r) and moves clockwise with an
acceleration .6m/s^2 .
When t=7 :
-Find position
-Find velocity
-Find acceleration

(Please note that the problem starts by saying "Last year", this
means that N will equal 18 (9x2) and not 20 (10x2).
Last year Carson Industries issued a
10-year, 12% semiannual coupon bond at its par value of $1,000.
Currently, the bond can be called in 6 years at a price of $1,060
and it sells for $1,150.

A ski jumper starts from rest from point A at the top of a hill
that is a height h1 above point B at the bottom of the hill. The
skier and skis have a combined mass of 80 kg. The skier slides down
the hill and then up a ramp and is launched into the air at point C
that is a height of 10m above the ground. The skier reaches point C
traveling at 42m/s.
(a) Is the...
