Question

Draw the figure and compute for the Section Properties ("x" and
"y") of the following built-up structural steel section:

Wide flange built-up from three (3) plates with dimensions
300mm x 20mm

Answer #1

y=6-2x-x^2 and y=x+6, about the x-axis. Draw the figure,
set up the integral needed to find the volume when the given curve
is rotated about the specified axis, find the answer. Use
calculator if needed!

Suppose that aaa = 190 mmmm. (Figure 1)
Figure
1 of 1A cross-section of a beam is shown on the xy-plane. The
x-axis is directed to the right and the y-axis is directed upward.
The cross-section consists of two parts. The first part is a
18-millimeter wide rectangle with a a vertical side of length a
placed so that its left side lies on the positive y-axis and the
bottom left corner is at the origin. The second part is...

Compute the line integral of f(x, y, z) = x 2 + y 2 −
cos(z) over the following paths:
(a) the line segment from (0, 0, 0) to (3, 4, 5)
(b) the helical path → r (t) = cos(t) i + sin(t) j + t k from
(1, 0, 0) to (1, 0, 2π)

1) Generate a data set with three variables (X, Y and Z). X and
Y have 10 observations for each (N=10), and Z has 13 observations
(N=13). Each observation should have two digits (such as “83” or
“8.3”).
2) Draw a stem-and-leaf display for variable Z only and draw a
box plot display for variable Z after specifying the 5 numbers
(UEX, LEX, FU, FL, MD).
3) Calculate the mean and standard deviation for variable X
4) Calculate the mean...

Write the new function f(x) that satisfies the following
conditions: y =/x/ is reflected with respect to the x-axis,
compressed by a factor of 1/3 , shifted to the left three units,
and up five units.
