Answer:

y =54

Step-by-step explanation:

We can use the equation y =kx

If we know y and x we can solve fork

24 = k*4

24/4 = k

6 =k

y = 6x

Substitute in 9

y =6*9

y =54

-5+ 3= 2) -7 -4 3) 122 × (-9) 4) -6 divided by 3/4

lutik1710 [3]

Answer:

Step-by-step explanation:

1) -5 +3 = -2

When two numbers are in different sign, subtract and the result will have the bigger numbers sign. The bigger number is 5. so the result is (-2)

2) -7 - 2 = -9

When two numbers have same sign, add and the result will have the common sign

3) 122 * (-9) = - 1098

4) -6 ÷ (3/4)

$=(-6)*\frac{4}{3}\\\\=-2*4$

= -8

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

gavmur [86]

$\nabla f=(ye^x+\sin y)\,\vec\imath+(e^x+x\cos y)\,\vec\jmath$

then

$\dfrac{\partial f}{\partial x}=ye^x+\sin y\implies f(x,y)=ye^x+x\sin y+g(y)$

Differentiating with respec to $y$ gives

$\dfrac{\partial f}{\partial y}=e^x+x\cos y=e^x+x\cos y+g'(y)$

$\implies g'(y)=0\implies g(y)=C$

So $F$ is indeed conservative, and

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