Mekhanik [1.2K]4 years ago
7 0

Answer:

All real numbers are solution for the inequality.

Step-by-step explanation:

Given expression:

2(-6n-5)

Solving the inequality.

Using the distribution.

(2(-6n))+(-2(-5)

-12n-10

Adding 12n to both sides.

-12n+12n-10

We have,

-10

The above statement is always true and thus the inequality has all real number solutions.

The number line graph for the inequality can be shown.

Determine the graph of the polar equation r =6/2-2cos theta<br> (picture provided)
vredina [299]

Answer:

Choice D is correct

Step-by-step explanation:

The first step is to write the polar equation of the conic section in standard form by dividing both the numerator and the denominator by 2;

r=\frac{3}{1-cos(theta)}

The eccentricity of this conic section is thus 1, the coefficient of cos θ. Thus, this conic section is a parabola since its eccentricity is 1.

The value of the directrix is determined as;

d = k/e = 3/1 = 3

The denominator of the polar equation of this conic section contains (-cos θ) which implies that this parabola opens towards the right and thus the equation of its directrix is;

x = -3

Thus, the polar equation represents a parabola that opens towards the right with a directrix located at  x = -3. Choice D fits this criteria

Phil and Stacy create repeating patterns using shapes. Phil's rule is "oval, square," and Stacy's rule is "oval, square, circle,
BigorU [14]

Using proportions, it is found that both patterns have the same number of ovals.

  • This question is solved by <em>proportions</em>, using rule of three.

For Phil:

  • There are 96 shapes.
  • 1 of each two shapes is oval, hence:

1 oval - 2 shapes

x oval - 96 shapes

Applying cross multiplication:

2x = 96

x = \frac{96}{2}

x = 48

For Stacy:

  • There are 96 shapes.
  • 2 of each two shapes are oval, hence:

2 oval - 4 shapes

x oval - 96 shapes

Applying cross multiplication:

4x = 192

x = \frac{192}{4}

x = 48

Both patterns have the same number of ovals.
