if you mean this:

x=21+2x

minus x on both sides

0=21-x

add 21 on both sides

21=-x

g Farmer Violet wants to enclose one 990 square foot rectangular area of land using fencing. One side will use special fencing costing $12 per foot. The remaining three sides of fencing will be formed using standard fencing costing $10 per foot. Find the dimensions of the corral that would minimize the cost of the fencing required for this project, rounded (if necessary) to the nearest hundredth of a foot

Answers

Answer:

Sides of the rectangular area:

x =  30  f

y =  33  f

Step-by-step explanation:

Let´s call   x  and y the sides of the rectangular area

A = x*y  = 990          y  = 990/x

The function cost is:

C = Costs ( sides x)  + costs ( sides y )

Cost of sides x    =  12*x +  10x

Cost of sides y    =  10*y  +  10 *y   =  2*10*y  = 20*y

C = 12*x + 10*x + 20*y =  22*x  + 20*y

The function cost as function of x is:

C(x)  = 22*x + 20*(990/y)  =  22*x  +  19800/x

Tacking derivative on both sides of the equation:

C´(x)  = 22  + [ - 19800/x²]

C´(x) = 0       22  - 19800/x²  =  0

Solving for x

22*x²  - 19800  =  0

22x²  =  19800

x² =  19800/22 =  900

x₁,₂ = ± 30        We dismiss negative root ( we never have negative lenghts)

Then     x =  30 f

And  y  =  990 / 30      y  = 33  

To see if x = 30 is a minimum for function C(x) we evaluate the second derivative.

C´´(x) = 2*x* 19800/x⁴      

C´´ (x) = 39600/x³    so C´´ is always greater than 0 then C (x) has a minimum at x = 30

Sides of the rectangular area are:

x  =  30

y  =  33

line parallel to y=8-1/8x

Answers

Answer:

Y = (-1/8) X + C is the equation of a line parallel to y=8-1/8x

Step-by-step explanation:

Complete question.

Find the line parallel to y=8-1/8x

Solution

For two lines to be parallel to each other it is essential that their slopes must be same

For any line of the form

Y = mX +b

m is the slope

Here the equation of given line is  y=8-1/8x

on rearranging, we get

Y = (-1/8) X + 8

here m = (-1/8)

Hence, line parallel to y=8-1/8x is any line with slope equal to (-1/8)

Or we can say that equation of parallel line would be

Y = (-1/8) X + C

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 24

A
12
D
24

Answers

Answer: x=48

Step-by-step explanation:

The length AC of the right-angle triangle will be 48 units.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.

AC / AB = AB / AD

AC / 24 = 24 / 12

AC = 48 units

The length AC of the right-angle triangle will be 48 units.

More about the right-angle triangle link is given below.

The ratio of 8:5=(?)% 1 It was the last day of school; the kids were gone, the books had been collected, and Principal Drake was handing out final paychecks. This was normally a relaxed meeting at which teachers wearing casual clothes smiled and wished each other well for the summer. But no one was smiling today, because a story in the local newspaper had exploded like a crack of thunder.2 The headline read, Board of Education Plans New Middle School, and the staff members of East Orange Elementary were rattled.3 Principal Tom Drake opined, I am concerned about a situation in which a newspaper already knows school district information that comes as a surprise to me and my teachers. He continued, But of far greater concern is what this means for us, for our colleagues at West Orange, and students and parents throughout the district.4 Coach Melinda Gardner whispered to her friend, Mr. Dale French, Old Tom is just worried the Board might ask him to retire and make someone else principal of the new campus.5 Mr. French whispered back, Melinda, you be nice now, but he couldnt help smiling at his friends remark.6 As the meeting went on, many teachers worried out loud about what might happen if grades 6-8 from East and 6-8 from West consolidated.7 Ever since the two elementary schools had opened, decades ago, the district had proudly maintained a unique system. While surrounding districts had built new middle schools, Orange kept two elementary buildingsEast and Westwith K-8 graders in each.8 Now, according to the paper, the results of the 2010 census were in. They suggested population growth would soon fill both elementary schools with K-5 students only. Apparently, the Board thought the time was ripe to build one new middle school for 6-8 graders.9Will one campus need two middle school science labs? Dr. Fred Davis, the science department head, asked the group in his usual shy, quiet voice.10Since there is only one middle school library, is the Board going to honor seniority? Mrs. Betty Green asked brashly. Or the Board could just keep whichever librarian has the coolest photos on her social media site, she added sarcastically.11Mrs. Green is worried her lack of computer skills might finally hurt her, Coach Gardner whispered to Mr. French again.12Coach Gardner, please! Principal Drake scolded his gym teacher for whispering. You would not tolerate it if your students were rude. This turn of events has caused real alarm so lets be sensitive to each others concerns.13I apologize for both of us, Tom, Mr. French offered. But lets not get carried away and spoil our summers over this. We dont know if this proposed new campus will actually be built. The census projections could be wrong. Even if they are right, the cost of raising taxes to pay for a new school might not go over well with voters.14 Mr. French continued, I plan to enjoy my summer and expect another great year. Chances are well all have jobs because several teachers retire every year and the Board moves us around to fill the vacancies. Some of us may have new assignments, but well all land somewhere.15 All around the room, there were nods of agreement. The atmosphere of gloom gave way to the usual feelings of accomplishment and relief at the end of school.16 Mr. French offered one more uplifting thought. Each spring we graduate our eighth graders and send them on to Central High. If they can adjust to a new building, I think we can too.17 With that, the teachers adjourned and summer vacation began.Write a complete and accurate summary of this text.

Help!solve this problem So im about done with my essay how does it look so farVaping can expose you to nicotine, and that can cause cravings and other symptoms of addiction. It can also expose your lungs to toxic metals like nickels, lead, chromium, tin, and aluminum. Nicotine changes the way your brain works so as a teen your brain is still developing and that can make it where you're more vulnerable to nicotine addiction. You inhale 3 chemicals when you vape. When addicted to vaping you can get popcorn lung and the effects are, coughing, wheezing, chest pain, shortness of breath. It also can affect your memory. 1. Diacetyl: This food additive, used to make the flavor, will damage small passageways in the lungs. It's also a compound found in foods and additives used for dairy flavoring. It's found in brown flavors, such as caramel, butterscotch, and other sweeteners. 2. Formaldehyde: This can cause lung disease and contribute to heart disease. It's a colorless, strong-smelling gas used in making building materials and many household products. It is also used in pressed-wood products, like particle board, plywood, and fiber board. 3. Acrolein: It's most often used as a weed killer, this can also damage lungs. It's a colorless liquid with a piercing, acrid smell. The smell of burnt fat. Vaping has some effects like tobacco as in picking at your face so much it leaves scars. It also gives you mood swings. Vaping can lead to other addictions in life. You will feel more anxious than usual. It can also lead to cancer, diabetes, eye problems, sickness, gum infection and disease, heart problems, impotence, infertility, lung disease, pregnancy complications. If you're athletic it would be harder to do your sport because you would lose breath faster and you wouldn't be able to do it for a long time. So if you play sports and you vape you will have to quit your sport or quit vaping. It also makes you depressed (more) because of the brain damage you're causing .
