1. Which of the following is equivalent to the inequality - 8 > 8x + 16 ?
Alex

Answer:

x <  -3 is the solution for the given inequality - 8 > 8x + 16.

Step-by-step explanation:

Here, the given inequality is  - 8 > 8x + 16

Now, we know if equal (positives) are added, subtracted multiplied or divided on both sides of in equality, the signs remain unchanged.

⇒  - 8 > 8x + 16 is equivalent  to   - 8   + 8  > 8x + 16  + 8

or,  0 >  8x  + 24

⇔ -8x  > 8x + 24 - 8x

⇔ -8 x >  24

or, \frac{-8x}{-8}   <   \frac{24}{-8} (REVERSE SIGN as dividing by a a negative number)

or, x < -3

or, x <  -3 is the solution for the given inequality.

The base of a circular fence with radius 10 m is given by x = 10 cos(t), y = 10 sin(t). The height of the fence at position (x,
kirill115 [55]

Answer:

  6.28 L

Step-by-step explanation:

The length of the circular fence is ...

  C = 2πr = 2π(10 m) = 20π m

The height in terms of t is ...

  h(t) = 5 +0.05((10cos(t))^2 -(10sin(t))^2) = 5 +5(1 -2sin(t)^2)

For 0 ≤ t ≤ 2π, the average value of this height function is 5.

The fence has an average height of 5 m and a length of 20π m, so an area of ...

  (one side) fence area = (5 m)(20π m) = 100π m²

The area of both sides is double this, or ...

  total fence area = 2(100π m²) = 2π(100 m²)

Since 1 liter covers 100 m², we need 2π liters to cover the fence.

The amount of paint needed is 6.28 L.

If the volume of a cubical box is 1728cm find its total surface area​
Lera25 [3.4K]

Answer:

<h2>864 cm²</h2>

Step-by-step explanation:

The formula of a volume of a cube:

V=s^3

<em>s</em> - <em>edge</em>

We have

V=1728\ cm^3

Substitute:

s^3=1728\to s=\sqrt[3]{1728}\\\\s=12\ cm[/texbecause[tex]12^3=1728

The formula of a surface area of a cube:

SA=6s^2

(6 square faces of a cube)

Substitute:

SA=6(12^2)=6(144)=864\ cm^2
