Let C be the unit circle in the xy-plane, oriented counterclockwise as seen from above. The divergence of the vector field F~ = (z, x, y) is zero, and as a result the flux through every surface with boundary C should be the same. Confirm that this is the case with the upper half of the unit sphere, the lower half of the unit sphere, and the unit disk in the xy-plane

An electronics firm sells four models of stereo receivers, three CD decks, and six speaker brands. When the three types of components are sold together, they form a "system." How many different systems can the electronics firm offer?A. 169
B. 72
C. 13
D. 36

Answers

Answer:

B. 72

Step-by-step explanation:

The total number of different systems that can be bundled together is the product of the possible number of ways to select 1 out of 4 stereo receivers, by 1 out of 3 CD decks and by 1 out of 6 speakers. Assuming that the order at which products are picked does not matter, the number of different systems is:

n=(4!)/((4-1)!1!)*(3!)/((3-1)!1!)*(6!)/((6-1)!1!)\nn=4*3*6\nn=72\ systems

The electronics firm can offer 72 different systems.

The given system of inequalities is expressed as

\begin{gathered} 24x\text{ + 8y }\ge\text{ 20} \n 3x\text{ - 6y > 24} \end{gathered}

The first step is to change the inequality symbols to that of 'equal to" and plot the straight line graph for each equation.

For the first equation, the line on the graph would be solid because the symbol is "greater than or equal to"

For the second equation, the line would be broken because the inequality symbol does not have an "=" symbol

The graph is shown below

1/2(3/5x-8)+7/4(2/5x+4)

Answers

Answer:

x + 3

Step-by-step explanation:

Use the distributive property, then collect like terms

(1/2)(3/5 x) + (1/2)(-8) + (7/4)(2/5 x) + (7/4)(4)

3/10 x - 4 + 7/10 x + 7

x + 3

What is f ( 1/3)? When the function is f(x) =-3x+7

Answers

Answer:

f(1/3) = 6

Step-by-step explanation:

f(x) =-3x+7

Let x = 1/3

f(1/3) =-3*1/3+7

        = -1 +7

       = 6

Answer:

f(1/3) = 6

Step-by-step explanation:

The function is:

● f(x) = -3x+7

Replace x by 1/3 to khow the value of f(1/3)

● f(1/3) = -3×(1/3) +7 = -1 +7 = 6
