PLEASE HELP!!!!! A satellite telescope has a parabolic dish. Satellite signals are collected at the focal point (focus) of the
parabola. The distance from the vertex of the parabolic dish to the focus is 40 feet. The vertex of the dish is
located at a point 50 feet above the ground and 100 feet to the east of a computer that reads and records
data from the telescope. The diameter of the dish is 160 feet.

Answers

The dish illustrates operations on a parabola.

The depth of the parabolish dish is 160 feet.

The bowl is said to be a parabola.

So, we have:

[tex]\mathbf{(x -h)^2 = 4p(y - k)}[/tex]

Where:

[tex]\mathbf{Focus: p = 40}[/tex]

[tex]\mathbf{Vertex:(h,k) = (0,0)}[/tex]

From the question, the diameter is 160 feet.

So, the radius (r) is:

[tex]\mathbf{r = \frac{160}{2} = 80}[/tex]

So, the coordinate of the depth of the parabola would be:

[tex]\mathbf{(x,y) = (60 + 100,y)}[/tex]

[tex]\mathbf{(x,y) = (160,y)}[/tex]

Substitute these values in [tex]\mathbf{(x -h)^2 = 4p(y - k)}[/tex]

So, we have:

[tex]\mathbf{(160 - 0)^2 = 4 \times 40 \times (y -0)}[/tex]

[tex]\mathbf{160^2 = 160y}[/tex]

Divide both sides by 160

[tex]\mathbf{160 = y}[/tex]

Rewrite as:

[tex]\mathbf{y = 160 }[/tex]

Hence, the depth of the parabolish dish is 160 feet.

Find the measure of the angle with the red dot (NOT X.)
Picture Included. Thank you!

Answers

Step-by-step explanation:

I can't see picture very well but as I see first angle is

-4x+5 and second is -13x+39 ( if it isn't, correct me)

sum of this angles is 180° because they are inner angles

(-4x+5) + (-13x+39) = 180

-4x+5 -13x+39=180

-17x+44=180

-17x = 180-44

-17x= 136

x= -8

angle -4x+5 will be:

-4*-8 + 5= 32+5= 37°

rectangular equation for the curve whose parametric equations are x = 2cosθ, y = cos2θ.

Answers

The rectangular equation for the curve is [tex]y = \frac{x^{2}}{2} -1[/tex].

In this question, we have a set of parametric equation which must be reduced into a single rectangular equation both by algebraic and trigonometric means, that is to say:

[tex]x = f(\theta), y = g(\theta) \to y = h(x)[/tex]

If we know that [tex]x = 2\cdot \cos \theta[/tex] and [tex]y = \cos 2\theta[/tex], then the rectangular equation is:

[tex]y = \cos 2\theta[/tex]

[tex]y = \cos^{2}\theta - \sin^{2}\theta[/tex]

[tex]y = 2\cdot \cos^{2}\theta -1[/tex]

[tex]\cos \theta = \frac{x}{2}[/tex]

[tex]y = 2\cdot \left(\frac{x}{2} \right)^{2}-1[/tex]

[tex]y = \frac{x^{2}}{2} -1[/tex]

The rectangular equation for the curve is [tex]y = \frac{x^{2}}{2} -1[/tex].

If Marie were to paint her living room alone, it would take 7 hours. Her sister Barbara could do the job in 8 hours. How many hours would it take them working together? Express your answer as a fraction reduced to lowest terms, if needed.

Answers

Answer:

[tex]\sf\longmapsto \: 3.73 hours [/tex]

Step-by-step explanation:

[tex]\sf\longmapsto \: \frac{1}{7 } + \frac{1}{8} [/tex]

[tex]\sf\longmapsto \: \frac{15}{56} [/tex]

Now, Reciprocal–

[tex]\sf\longmapsto \: \frac{56}{15} [/tex]

[tex]\sf\longmapsto \: 3.73 hours [/tex]

The time taken together Marie and his sister to paint the living room are 3.73 hours or 3 hours and 43.8 minutes.

What are work and time?

Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.

Another illustration of labor is when you finish your meal in an hour, which means that you finished your work in an hour.

Given that,

Marie take 7 hours to paint

1 work → 7 hour

1 hour → (1/7) work

Barbara takes 8 hour

1 work → 8 hour

1 hour → (1/8) work

Let's suppose together they take x hour

1 work → x hour

1 hour → (1/x) work

Now,

1-hour work together = 1-hour work of Marie + 1-hour work of Barbara

(1/x) = (1/7) + (1/8)

(1/x) = (7 + 8)/56

x = 56/15

x = 3.73

x = 3 hour and 0.73 × 60 = 43.8 minutes.

Hence "The time taken together Marie and his sister to paint the living room is 3.73 hours or 3 hours and 43.8 minutes".

The correct quotient is -3

The mistake CJ likely made is multiplying using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

From the question,

We are to determine the correct quotient.

The given division operation to be carried out is -3/4 divided by 1/4

The correct quotient can be determined as shown below

[tex]-\frac{3}{4} \div \frac{1}{4}[/tex]

Multiply [tex]-\frac{3}{4}[/tex] by the reciprocal of [tex]\frac{1}{4}[/tex]

The reciprocal of [tex]\frac{1}{4}[/tex] is  [tex]\frac{4}{1}[/tex]

Then, we get

[tex]-\frac{3}{4} \times \frac{4}{1}[/tex]

This gives

[tex]-\frac{12}{4}[/tex]

= -3

The correct quotient is -3

The mistake CJ likely made is multiplying using the reciprocal of -3/4.

Hence, the correct quotient is -3

The mistake CJ likely made is He multiplied using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

But before doing so, there were a few words that he felt it incumbent upon him to say.It was a source of great satisfaction to him, he saidand, he was sure, to all others presentto feel that a long period of mistrust and misunderstanding had now come to an end. There had been a timenot that he, or any of the present company, had shared such sentimentsbut there had been a time when the respected proprietors of Animal Farm had been regarded, he would not say with hostility, but perhaps with a certain measure of misgiving, by their human neighbours. Unfortunate incidents had occurred, mistaken ideas had been current. It had been felt that the existence of a farm owned and operated by pigs was somehow abnormal and was liable to have an unsettling effect in the neighbourhood. Too many farmers had assumed, without due enquiry, that on such a farm a spirit of licence and indiscipline would prevail. They had been nervous about the effects upon their own animals, or even upon their human employees. But all such doubts were now dispelled. Today he and his friends had visited Animal Farm and inspected every inch of it with their own eyes, and what did they find? Not only the most up-to-date methods, but a discipline and an orderliness which should be an example to all farmers everywhere. He believed that he was right in saying that the lower animals on Animal Farm did more work and received less food than any animals in the county. Indeed, he and his fellow-visitors today had observed many features which they intended to introduce on their own farms immediately.What results from the human farmers visit to Animal Farm?
