Answer: A∩B is an empty set.

A∩B=\phi

OR

A∩B= { }


Step-by-step explanation:

Given : A = {the sum of the number cubes is odd}

and  B = {the sum of the number cubes is divisible by 2}

We know that odd numbers is not divisible by 2 .

Therefore, the both set have no element common.

Thus, their intersection will be an empty set.

A∩B is an empty set.

A∩B=\phi

OR

A∩B= { }

Evaluate the surface integral. S xz ds, s is the part of the plane 2x 2y z = 4 that lies in the first octant
maksim [4K]

The value of the given surface integral is 4.

The given plane intercepts the coordinate axes at (2, 0, 0), (0, 2, 0), and (4, 0, 0). These point are the coordinates of a triangular region that we can parameterize using.

S(u,v)=(1-u)((1-u)(2,0,0)+u(0,2,0)+u(4,0,0)\\S(u,v)=(2(1-u)(1-v),2u(1-v),4v)

<h3>What is the surface integral?</h3>

A surface integral is a generalization of multiple integrals to integration over surfaces. It can be thought of as the double integral analog of the line integral. Given a surface, one may integrate a scalar field over the surface or a vector field.

with 0≤u≤1 and  0≤v≤1. Then the surface element ds  is equivalent to

ds=\||\:\left(s_u\times \:\:S_v\right)||dudv=12\left(1-v\right)dudv

The surface integral is then

\int \:\int \:_Sxzds=12\int _0^1\:\int _0^1\:\left(2\left(1-u\right)\left(1-v\right),2u\left(1-v\right),4v\right)dvdu=4

Therefore the value of the given surface integral is 4.

Can someone help me with my math homework? It is due today and I don’t understand. Could you also explain how you got the answer
Assoli18 [71]

Answers

(1) a = 16 , (2) x =4 , (3) x = 0 ,(4) n =-20 , (5) r = 20 and (6) x = -11

Step-by-step explanation:

(1) 6 = a/4 + 2

4 = a/4 (It is because when you bring +2 over to the left it will become 6 -2)

a = 16 (it is because of the fraction, so when you bring the divisor over it becomes x 4)

The following questions same as qns 1 too

(2) -6 + x/4 = -5

x/4 = 1

x = 4

(3) 9x -7 = -7

9x = 0

x = 0

(4) 0 = 4 + n/5

-4 = n/5

n = -20

(5) -4 = r/20 -5

1 = r/20

20 = r

(6) -1 = 5 + x/6

-6 = 5 + x

-11 = x
