Find the value of each variable listed.

baherus [9]

Answer:

a = 90

b = 28

c = 68

d = 22

Step-by-step explanation:

$a = 90$

$d=22$

$22+90=112$

$180-112=68$

$c=68$

$62+90=152$

$180-152=28$

$b=28$

Determine whether or not f is a conservative vector field. if it is, find a function f such that f = ∇f. (if the vector field is

sineoko [7]

$\mathbf f(x,y)=(ye^x+\sin y)\,\mathbf i+(e^x+x\cos y)\,\mathbf j$ is continuous, so $\mathbf f(x,y)$ is indeed conservative. So we know there is some scalar function $f(x,y)$ such that $\nabla f(x,y)=\mathbf f(x,y)$ .

$\dfrac{\partial f}{\partial x}=ye^x+\sin y$
$\displaystyle\int\frac{\partial f}{\partial x}\,\mathrm dx=\int(ye^x+\sin y)\,\mathrm dx$
$f(x,y)=ye^x+x\sin y+g(y)$

$\dfrac{\partial f}{\partial y}=\dfrac{\partial(ye^x+x\sin y+g(y))}{\partial y}$
$e^x+x\cos y=e^x+x\cos y+g'(y)$
$0=g'(y)$
$\implies g(y)=C$

So we have

$f(x,y)=ye^x+x\sin y+C$

On monday eliza read her book. on tuesday she read three times as long as she read on monday. on wednesday she read 20 minutes l

stich3 [128]

Monday : x
tuesday : 3x
wednesday : 3x - 20 = 40
thursday: 20

3x - 20 = 40
3x = 40 + 20
3x = 60
x = 60/3
x = 20

monday : 20 minutes
tuesday : 3x....3(20) = 60 minutes
wednesday : 40 minutes
thursday: 20
for a total of : 140 minutes <===
