Use the Divergence Theorem to evaluate ∫∫ ? ∙ ?? where ? =
??2 ?⃑+ (??2 − 3?4 )?⃑+
(?3 + ?2 )? and S is the surface of the
sphere of radius 4 with ? ≤ 0 and ? ≤ 0 . would spherical
coordinates work?
Prove the necessary part of Ceva’s Theorem for the case where D
and E are ideal but F is ordinary.
The case is where: D and E are ideal but F is
ordinary.
Lately I feel as though the people working for Chegg prematurly
take on questions they cannot answer. If you do not know the answer
that is ok but please do not accept the question if you do not
think you can answer it. Someone anonymously accepted this question...
1. Explain the meaning of Systematic risk?
2. Explain the meaning of Jensen's alpha ( and some graph will
be included)
Please, explain in detail as much as possible.
consider a system with the impulse response
h(t) = e −t [u(t) − u(t − 2)]. (It's exponential function)
Let the input signal x(t) be x(t) = 1 if 0 ≤ t < 1, x(t) = −1
if 1 ≤ t < 2, x(t) = 0 otherwise.
(a) Determine the system output y(t).
(b) (20) Plot y(t) using a computer and specify the maximum and
minimum.
Sociology
Explain in your own words.
1.The meaning of science of sociology
2. The meaning of C. Wright Mills theory and argument. EXPLAIN IN
YOUR OWN WORDS how you relate to his theory, and produce examples
from your daily life to explain what he says.
Let Zt = U sin(2*pi*t) + V cos(2*pi*t), where U and V are
independent random variables, each with
mean 0 and variance 1.
(a) Is Zt strictly stationary?
(b) Is Zt weakly stationary?
Assume an investor with the following utility function: U = E(r)
- 3/2(s2).
If the investors pportfolio has an expected return of 10.9 and
