1 Two negatives make a positive
\frac{3}{4}(8x-12)=5x-2
​4
​
​3
​​ (8x−12)=5x−2

2 Simplify \frac{3}{4}(8x-12)
​4
​
​3
​​ (8x−12) to \frac{3(8x-12)}{4}
​4
​
​3(8x−12)
​​
\frac{3(8x-12)}{4}=5x-2
​4
​
​3(8x−12)
​​ =5x−2

3 Factor out the common term 44
\frac{3\times 4(2x-3)}{4}=5x-2
​4
​
​3×4(2x−3)
​​ =5x−2

4 Simplify 3\times 4(2x-3)3×4(2x−3) to 12(2x-3)12(2x−3)
\frac{12(2x-3)}{4}=5x-2
​4
​
​12(2x−3)
​​ =5x−2

5 Simplify \frac{12(2x-3)}{4}
​4
​
​12(2x−3)
​​ to 3(2x-3)3(2x−3)
3(2x-3)=5x-23(2x−3)=5x−2

6 Expand
6x-9=5x-26x−9=5x−2

7 Add 99 to both sides
6x=5x-2+96x=5x−2+9

8 Simplify 5x-2+95x−2+9 to 5x+75x+7
6x=5x+76x=5x+7

9 Subtract 5x5x from both sides
6x-5x=76x−5x=7

10 Simplify 6x-5x6x−5x to xx
x=7x=7

Draw a rectangle having the base congruent to the nine sevenths of the height.

Let

b-------> the base of rectangle

h-------> the height of rectangle

we know that

b=(9/7)*h-------> this is the equation to obtain the base of the rectangle for a given height

examples

1) for h=7 units

b=(9/7)*7-------->b=9 units

the dimensions are 9 units x 7 units------> see the attached figure

2) for h=5 units

b=(9/7)*5-------->b=(45/7) units

the dimensions are (45/7) units x 5 units

The answer in Italian

Facciamo

b-------> base del rettangolo

h-------> altezza del rettangolo

Noi sappiamo che

b=(9/7)*h-------> questa è l'equazione per ottenere la base del rettangolo per una determinata altezza

esempi

1) per h=7 units

b=(9/7)*7-------->b=9 units


le dimensioni sono 9 units x 7 units-----> vedere la figura allegata

2) per h=5 units

b=(9/7)*5-------->b=(45/7) units


le dimensioni sono (45/7) units x 5 units

Set up a double integral for calculating the flux of the vector field ????⃗ (????⃗ )=????⃗ , where ????⃗ =⟨x,y,z⟩, through the p
Tema [17]

Answer:

-937.5π

Step-by-step explanation:

F (r) = r = (x, y, z) the surface equation z = 3(x^2 + y^2) z_x = 6x, z_y = 6y the normal vector n = (- z_x, - z_y, 1) = (- 6x, - 6y, 1)

Thus, flux ∫∫s F · dS is given as;

∫∫ <x, y, z> · <-z_x, -z_y, 1> dA

=∫∫ <x, y, 3x² + 3y²> · <-6x, -6y, 1>dA , since z = 3x² + 3y²

Thus, flux is;

= ∫∫ -3(x² + y²) dA.

Since the region of integration is bounded by x² + y² = 25, let's convert to polar coordinates as follows:

∫(θ = 0 to 2π) ∫(r = 0 to 5) -3r² (r·dr·dθ)

= 2π ∫(r = 0 to 5) -3r³ dr

= -(6/4)πr^4 {for r = 0 to 5}

= -(6/4)5⁴π - (6/4)0⁴π

= -937.5π

A rectangular storage container with an open top is to have a volume of 10 m3. The length of this base is twice the width. Mater
Gala2k [10]
L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W 
C ` = 60 W - 270 / W² 
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.
