Consider F and C below. F(x, y, z) = yz i + xz j + (xy + 6z) k C is the line segment from (2, 0, −2) to (5, 4, 2) (a) Find a fun

WITCHER [35]

Answer:

Required solution (a) $f(x,y,z)=xyz+3z^2+C$ (b) 40.

Step-by-step explanation:

Given,

$F(x,y,z)=yz \uvec i +xz\uvec j+(xy+6z)\uvex k$

(a) Let,

$F(x,y,z)=yz \uvec i +xz\uvec j+(xy+6z)\uvex k=f_x \uvec{i} +f_y \uvex{j}+f_z\uvec{k}$

Then,

$f_x=yz,f_y=xz,f_z=xy+6z$

Integrating $f_x$ we get,

$f(x,y,z)=xyz+g(y,z)$

Differentiate this with respect to y we get,

$f_y=xz+g'(y,z)$

compairinfg with $f_y=xz$ of the given function we get,

$g'(y,z)=0\implies g(y,z)=0+h(z)\implies g(y,z)=h(z)$

Then,

$f(x,y,z)=xyz+h(z)$

Again differentiate with respect to z we get,

$f_z=xy+h'(z)=xy+6z$

on compairing we get,

$h'(z)=6z\implies h(z)=3z^2+C$ (By integrating h'(z)) where C is integration constant. Hence,

$f(x,y,z)=xyz+3z^2+C$

(b) Next, to find the itegration,

$\int_C \vec{F}.dr=\int_C \nabla f. d\vec{r}=f(5,4,2)-f(2,0,-2)=(52+C)-(12+C)=40$

Answer:

Peter is a compulsive gamer. He decides to buy World of Warcraft, all of its expansions, Starcraft 2, a PS3, a Wii, and an Xbox 360 since prices in general have been rising at an alarming rate. INFLATION 
 Melissa decides to start her own personal library and chooses to amass a private collection of books and magazines about world religions, cooking, comics, and economics. As she reads an issue of The Economist, she discovers overall price levels have changed only 0.01% in the past 2 years and decides it doesn't matter whether she starts the project now or later. PRICE STABILITY
Linda postpones her wedding even though most food prices and most service prices were dropping this year, which would help keep the cost of the wedding down. DEFLATION

Linda's money earned the most value because deflation means that the currency is gaining value as time passes. It is the opposite to inflation where a currency loses value as time passes.
