...

The steps

Multiply all terms by (x-3)(x+3) and cancel:

x(x+3)+2x(x−3)=18

3x2−3x=18(Simplify both sides of the equation)

3x2−3x−18=18−18(Subtract 18 from both sides)

3x2−3x−18=0

3(x+2)(x−3)=0(Factor left side of equation)

x+2=0 or x−3=0(Set factors equal to 0)

x=−2 or x=3

Check answers. (Plug them in to make sure they work.)

x=−2 (Works in original equation)

x=3 (Doesn't work in original equation)

The solution set for the number line of inequality can be represented as,

{x | x ≤ 4. 5}

The number line is the way of representation of number and digits in a arranged form to understand the data batter.

The meaning of circle in number line,

The number line going from negative 5 to positive 5 and a solid circle appears between positive 4 and positive 5. The middle point of 4 and 5 is 4.5.

The solid or closed circle means that the value has less than or equal to 4.5. Thus, the solution set for the number line of inequality can be represented as,

{x | x ≤ 4. 5}

Attached is what the graph should look like.

Step-by-step explanation:

|2x + 2| > 4

Separate the equations into two different ones:

2x + 2 > 4                                                    2x + 2 < - 4

Answer:

  (b)  19.6 square feet

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr²

If the diameter is 5 feet, the radius is 2.5 feet, so the area is ...

  A = (3.14)(2.5 ft)² ≈ 19.625 ft² ≈ 19.6 ft²

The area of a base circle is about 19.6 square feet.

Answer:

19.6 square feet

Answer:

  g(x) = 3f(-x/2)

Step-by-step explanation:

g(x) is 3 times the height of f(x), and 2 times its width. It is also reflected over the y-axis.

The relevant transformations are ...

  g(x) = k·f(x) . . . . scales f(x) vertically by a factor of k

  g(x) = f(-x) . . . . . reflects f(x) over the y-axis

  g(x) = f(x/k) . . . . scales f(x) horizontally by a factor of k

__

The three transformations we described at the beginning mean that g(x) is ...

  g(x) = 3f(-x/2)

Answer:

11.08 cm/s

Step-by-step explanation:

Here it is given that the edges of a cube are increasing at a rate of 6.4 cm/s . And we need to find out the rate at which the diagonals are increasing . If we assume each side of the cube to be x , then ;

[tex]\longrightarrow \dfrac{da}{dt}= 6.4 \ cm/s\dots (i) [/tex]

Now we can find diagonal as ,

[tex]\longrightarrow d = \sqrt{ length^2+breadth^2+height^2} [/tex]

Here l = b = h = a ; so ,

[tex]\longrightarrow d =\sqrt{ a^2+a^2+a^2} [/tex]

Simplify,

[tex]\longrightarrow d =\sqrt{3a^2} [/tex]

Take out a from square root,

[tex]\longrightarrow d =\sqrt3 a[/tex]

Now , we can find the rate of change of diagonal as ;

[tex]\longrightarrow r =\dfrac{d\sqrt3 a}{dt} [/tex]

Take out the constant,

[tex]\longrightarrow r = \sqrt3\dfrac{da}{dt} [/tex]

From equation (i),

[tex]\longrightarrow r = 1.732 \times 6.4 \ cm/s [/tex]

Multiply ,

[tex]\longrightarrow \underline{\underline{ rate_{of\ change \ of \ diagonals}= 11.08\ cm/s}}[/tex]

This is the required answer!

If the side length increases at a rate of 6.4 cm/s, then the diagonal increases at a rate of 11.1 cm/s

The diagonal of a cube of side length S is given by:

d = S*√3

In this case, we know that the side length increases at a rate of 6.4 cm/s, then we can write:

S = S₀ + 6.4cm/s*t

Where S₀ is the initial side length, replacing that on the diagonal formula we get:

d = (S₀ + 6.4cm/s*t)*√3

Now if we differentiate it with respect to the time t, we get:

d' = 6.4cm/s*√3 = 11.1 cm/s

So, if the side length increases at a rate of 6.4 cm/s, then the diagonal increases at a rate of 11.1 cm/s.

To solve this problem, we can use cross multiplication:

First, we can to convert inches into feet so...

5 inches = 0.416667 ft

7 inches = 0.583333 ft

(0.416667 ft/ 0.583333 ft) = (12 ft/ x ft)

x = 16.8 ft

So the actual width is 16.8 ft.
