<h2>The answer is: D</h2>

(12 x 4= 48) + (4 x 2=8) = 56

The 4 is for the $4 amount spent on adult tickets. The 2 is for the $2 amount spent on child tickets.

HOPE THIS HELPS!

Answer:

D) 12 adult tickets and 4 child tickets

Step-by-step explanation:

I did process of elimination

A) 4*4=16

12*2 = 24

16+24=40 is not equal to 56

B) 8*4=32

8*2=16

32+16= 48 is not equal to 56

C) 10*4=40

6*2=12

40+12=52 is not equal to 56

D) 12*4=48

4*2=8

48+8=56 is equal to 56

Answer:

38cm taller

Step-by-step explanation:

jack is 178cm tall

the ladder is 280cm tall

jack standing on the ladder is 280cm taller

so 178+280=458

the tree is 420cm tall

458>420

which means that jack is now taller than the tree standing in the ladder

458-420=38

so jack is 38cm taller than the tree standing on the top of the ladder

Use Green's Theorem to calculate the circulation of F =2xyi around the rectangle 0≤x≤8, 0≤y≤3, oriented counterclockwise.

Tamiku [17]

Green's theorem says the circulation of $\vec F$ along the rectangle's border $C$ is equal to the integral of the curl of $\vec F$ over the rectangle's interior $D$ .

Given $\vec F(x,y)=2xy\,\vec\imath$ , its curl is the determinant

$\det\begin{bmatrix}\frac\partial{\partial x}&\frac\partial{\partial y}\\2xy&0\end{bmatrix}=\dfrac{\partial(0)}{\partial x}-\dfrac{\partial(2xy)}{\partial y}=-2x$

So we have

$\displaystyle\int_C\vec F\cdot\mathrm d\vec r=\iint_D-2x\,\mathrm dx\,\mathrm dy=-2\int_0^3\int_0^8x\,\mathrm dx\,\mathrm dy=\boxed{-192}$

Can somebody help me with this ?? :)

Answer:

Your answer would be D, the equation is a function because it is a polynomial and all polynomials are functions.

Step-by-step explanation:

I like to remember that polynomials have no negative , fraction exponents and no division. In this case everything is positive so I knew it was a polynomial , and like the answer says all polynomials are functions !

Hope this helped
