hello your question is incomplete below is the complete question

verify the conclusion of Green's Theorem by evaluating both sides of the equation for the field F= -2yi+2xj. Take the domains of integration in each case to be the disk. R: x^2+y^2 < a^2 and its bounding circle C: r(acost)i+(asint)j, 0<t<2pi. the flux is ?? the circulation is ??

answer :  attached below

Step-by-step explanation:

Attached below is the required verification of the conclusion of Green's Theorem

In the attached solution I have  proven that Green's theorem ( ∫∫c F.Dr ) .

i.e. ∫∫ F.Dr = ∫∫r ( dq/dt - dp/dy ) dx dy = 4πa^2

Answer:

B

Step-by-step explanation:

In a triangle the longest side is opposite the largest angle.

∠ Y = 180° - (60 + 43)° = 180° - 103° = 77°

∠ Y is the largest angle in the triangle, then the side opposite is the longest

That is XZ is the longest side → B

Answer: A

Step-by-step explanation:

she can carry 1.5 pounds of books plus the extra 3 pounds as long as its less than or equal to 15 lbs

The inequality that shows the number of books that Diana can carry in her bag if she has her lunch and gym shoes is 3 + 1.5x  ≤ 15.

The first step is to determine the total weight of the items in her bag:

1 + 2 = 3lbs

The second step is to determine the inequality sign to use:

the inequality sign to be used is the less than or equal to sign - ≤

The equation becomes: weight of items in her bag + (weight of one book x total number of books) ≤ weight the bag can carry

3 + 1.5x  ≤ 15

Answer:

6 friends can share the pizza

Step-by-step explanation:

1 1/2 ÷ 1/4 =6

Answer:

Divide 1 1/2 by 1/4. Note that 1 1/2 = 1 2/4 = 6/4. So now we divide 6/4 by 1/4, obtaining 6.

6 friends can enjoy an equal share.

This question is incomplete, the complete question is;

A sociologist wants to construct an 80 confidence interval for the proportion of children aged 8-10 living in New York who own a cell phone.

(a) A survey by the National Consumers League taken in 2012 estimated the nationwide proportion to be 036. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.02?

Answer:

the required or needed sample size is 946

Step-by-step explanation:

Given the data in the question;

confidence level = 80%

⇒ 100( 1 - ∝ )% = 80%

100 - 100∝ = 80

100∝ = 100 - 80

∝ = 20/100

level of significance ∝ = 0.2

[tex]Z_{\alpha /2[/tex] = [tex]Z_{0.10[/tex] = 1.2816 { from z-table }

p = 0.36

Allowable margin of error E = 0.02

let n be the required sample size.

we know that

E = √( p( 1 - p) / n )

given that margin of error E = 0.02

⇒ √( p( 1 - p) / n ) × [tex]Z_{\alpha /2[/tex] = 0.02

⇒ √( 0.36( 1 - 0.36) / n ) × 1.2816  = 0.02

⇒ √( 0.2304 / n ) × 1.2816 = 0.02

√( 0.2304 / n ) = 0.02 / 1.2816

√( 0.2304 / n ) = 0.01560549

( 0.2304 / n ) = ( 0.01560549)²  

0.2304 / n  = 0.000243531318

n = 0.2304 / 0.000243531318

n = 946

Therefore, the required or needed sample size is 946

Answer:

x=2

Step-by-step explanation:

The solution is, The equation the line is, x =2

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have to points (2,4) and, (2,-7)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>(y-4)/(x-2)=(-7-4)/(2-2)

=>0 = x-2

=>x =2

Hence, the required equation is,  x =2

[tex]-\frac{1}{9}[/tex]

Step-by-step explanation:

between (1, 9) and (10, 8), the x moves by 9 and y moves by -1

The slope is equal to: [tex]\frac{\Delta y}{\Delta x} = \frac{-1}{9} = -\frac{1}{9}[/tex]

Answer:

-1/9

Step-by-step explanation:

Here is the explanation I wrote on the paper. ASK QUESTIONS IN THE COMMENTS! I absolutely LOVE answering questions, and you understanding what I mean in my answer means the world to me.

Answer and Step-by-step explanation:

Expressions that represent the total area are:

6(m + n)

6n + 6m

(n + m)6

That is because to find the area of these rectangles, we multiply the length by the width. We would get 6m and 6n, which is one of those options.

Now, if we take out the 6 from each of the values, we get 6(m + n), or (n + m)6.

Answer:

WT=63

Step-by-step explanation:

[tex] \frac{56}{5 \times x + 3} = \frac{40}{4 \times x - 3} \\ x = 12[/tex]

So

[tex]5 \times x + 3 = 5 \times 12 + 3 = 63[/tex]

36^6 or 2176782336

Step-by-step explanation: if you multiply 10^2 would equal because you would multiply 10 by 10 and 4^3 would equal 64 because you would have to multiply four 3 times (4 x 4 x 4) and you subtract 100 and 64 (100 - 64) and you get 36 BUT, the question says "Give your answer as APO 6, so you put your answer as 36^6 or 2,176,782,336

Answer:

5 stick lengths

Step-by-step explanation:

The question is not structured well. However, the following can be deduced

[tex]Wire = \frac{5}{8}yd[/tex]

[tex]Stick = \frac{1}{8}yd[/tex]

Required

How many of the stick length can be gotten from the wire length

To do this, we simply divide the length of the wire by the length of the stick.

So, we have:

[tex]Number = \frac{Wire}{Stick}[/tex]

[tex]Number = \frac{5/8yd}{1/8yd}[/tex]

[tex]Number = \frac{5/8}{1/8}[/tex]

Using a calculator, we have:

[tex]Number = 5[/tex]
