Answer 2

The graph of the inequality is the second graph.

Which graph represents all the numbers x ≤ -1?

The graph will be a number line, such that we have a closed circle at x = -1, and we shade the region to the left (because x must be smaller than -1).

By looking at the possible options, we can see that the number line that meets this condition is the second one, the graph on the upper right corner.

That is the graph of the inequality: x ≤ -1.

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios. The longest side of a right triangle is called the hypotenuse and the other two sides are called the legs.

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides as follows:

Cosine Ratio

[tex]\displaystyle \cos\theta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]

Sine Ratio

[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

Consider the angle of θ=30°, then we can write:

[tex]\displaystyle \cos 30^\circ=\frac{x}{12\sqrt{3}}[/tex]

Solving for x:

[tex]x=12\sqrt{3}\cos 30^\circ[/tex]

Since:

[tex]\cos 30^\circ=\frac{\sqrt{3}}{2}[/tex]

Then:

[tex]x=12\sqrt{3}\cdot \frac{\sqrt{3}}{2}[/tex]

[tex]x = 18[/tex]

Now apply the sine:

[tex]\displaystyle \sin 30^\circ=\frac{y}{12\sqrt{3}}[/tex]

Solving for y:

[tex]y=12\sqrt{3}\sin 30^\circ[/tex]

Since:

[tex]\sin 30^\circ=\frac{1}{2}[/tex]

Then:

[tex]y=12\sqrt{3}\cdot \frac{1}{2}[/tex]

[tex]y = 6\sqrt{3}[/tex]

Find WZY. (helpp fast)

Answers

Answer:

[tex]m\angle WZY = 24^\circ[/tex]

Step-by-step explanation:

Angles and Lines

The figure shows two triangles WXZ and WYZ. Considering:

* Angles WXZ and WYZ are right (90°)

* Sides XW and YW are congruent (red marker on both)

* They share the side WZ.

We can conclude they are congruent. Thus, angles XZW and YZW are congruent or have the same measure:

5x + 4 = 6x

Subtracting 5x:

4 = x

Or, x =4

Thus:

[tex]m\angle WZY = 6x = 24^\circ[/tex]

Answers

Answer:

V= 50.27

Step-by-step explanation:

V=(3.14)4^2(3/3)

50.27

The volume of the cone created by mike with diameter of 3 feet is 50.24 feet³

Volume of cone-based problem:

What information do we have?

Diameter of cone = 8 feet

Height of cone = 3 feet

Radius of cone = 8 / 2

Radius of cone = 4 feet

Volume of cone = (1/3)(π)(r²)(h)

Volume of cone = (1/3)(3.14)(4²)(3)

Volume of cone = (1/3)(3.14)(16)(3)

Volume of cone = 50.24 feet³

The dots above -10 and 10 are not shaded in meaning those x values do not count towards the domain meaning we will use parenthesis instead of brackets for interval notation or no equal to signs in inequality notation.

Answer:

(3x+21)(x-5)

Step-by-step explanation:

To solve this let's create an equation that has intercepts at -7 and 5

To do this we get the following

(x+7)(x-5)

Now we need to make sure that the line passes through (4,-33) To do so we will plug in 4 to see how far off we are

If you plug in 4 into x you should get -11

To make y= -33 we simply need to put a three in the front and then distribute it to the first bracket

So we have

3(x+7)(x-5)

then distribute the 3 to get

(3x+21)(x-5)

Write an equation of the line that passes through the given points.

Answers

Answer:

y = 8/6x + 10/3

Step-by-step explanation:

You find the slope (m) first which is

Change of y over change of x

(6) - (-2) over (2)- (-4)

8/6 = m

Then you plug it into the equation y = mx + b

y = (8/6)x + b

Now you pick any of the set of points to plug in for x and y to solve for b

(6) = (8/6)(2) + b

6 = 8/3 + b

b = 10/3

Then plug into the equation for just m and b to get the equation of the line that passes thru both sets of points.

y = 8/6x + 10/3

Read this passage about Christopher Reeve.Christopher Reeve was born on September 25, 1952, in New York City. His mother was a journalist, and his father was a professor. As a kid he played sports, did well in school, and liked acting. His passion for acting goes back to playing with his brother when they were little. Reeve acted in his first play at the age of nine. After attending college, taking acting classes, and acting in many plays and movies, Reeve landed his biggest role. In 1978, he played the title role in Superman. He received very positive reviews for his performance and starred as Superman in all the sequels. Reeve was soon acting as the lead role in dozens of movies after Superman. Once well-known, Reeve used his celebrity status for good causes, such as visiting very sick children through the Make-A-Wish foundation. He was also a track and field coach at the Special Olympics.Besides acting, Reeve was also a licensed pilot and liked horseback riding. He learned to ride horses for a movie role, and he continued riding in his free time. Unfortunately, while riding one day in 1995, Reeve fell from his horse and became paralyzed from the neck down. Being confined to a wheelchair did not hold back Reeve from being socially active, and after many surgeries and rehabilitation, he decided to dedicate his life to helping people with spinal-cord injuries. He created the Christopher Reeve Foundation, which supports the improvement of the lives of people with disabilities and helps fund research to find a cure for paralysis. He was also politically active, working with senators to make sure that people with disabilities were treated fairly in the workplace. Reeve received many awards for his dedication to public service. He also wrote two books about his experiences, and a documentary was made about his life. Reeve passed away in 2004, but his legacy lives on today. He touched the lives of many people and showed us what it means to overcome extreme odds by never giving up.Which fact would be most appropriate to include in a yearbook page about Reeve?Reeve created a foundation to help people with disabilities.Reeve spent time working with senators.Reeve learned to ride horses for a role in a movie.Reeve enjoyed playing with his brother when they were little.
