The formula for volume always involves three dimensions.

tan 205

sin 25°

cos 65

cos 245

Answers

9514 1404 393

Answer:

tan(205°) = asin(25°) = (a√(a²+1))/(a²+1)cos(65°) = (a√(a²+1))/(a²+1)cos(245°) = -(a√(a²+1))/(a²+1)

Step-by-step explanation:

The tangent function is periodic with a period of 180°. So ...

tan(205°) = tan(25°) = a

The identity relating sine and tangent is ...

sin(x) = tan(x)/√(tan²(x)+1)

Rationalizing the denominator gives ...

sin(x) = tan(x)√(tan²(x)+1)/(tan²(x)+1)

sin(25°) = a√(a²+1)/(a²+1)

cos(65°) = sin(25°) = a√(a²+1)/(a²+1)

cos(245°) = -sin(25°) = -a√(a²+1)/(a²+1)

Answer:

y ≈ 2.262

Step-by-step explanation:

Using the rule of logarithms

log[tex]x^{n}[/tex] = nlogx

Given

[tex]3^{y}[/tex] = 12 ( take log of both sides )

log[tex]3^{y}[/tex] = log12 , then

ylog3 = log12 ( divide both sides by log3 )

y = [tex]\frac{log12}{log3}[/tex] ≈ 2.262 ( to 3 dec. places )

Answers

Step-by-step explanation:

[tex]8x - 3 = 5 + 4y[/tex]

Isolate y first subtract 5 from both sides

[tex]8x - 8 = 4y[/tex]

Divide both sides by 4.

[tex] \frac{8x - 8}{4} = y[/tex]

[tex]2x - 2 = y[/tex]

y= 1

Step-by-step explanation:

Solve for y:

8x - 3 = 5 + 4y

8x = 4y + 5+3

Divide both sides by 8

x = 1÷2y + 1

plug into equation

8 (1÷2y +1) - 3 = 5 + 4y

Distribute

8÷2+ 8 - 3 = 5 + 4y

4 + 5 -5 = 4y

Combine like item

4 = 4y

divide both sides by 4

y= 1

The diagram represents the fencing around a backyard. The fence is formed with parallel lines and a half circle. Write and solve an equation to determine how many feet of fencing are needed. Round the answer to the nearest tenth.

Answers

The amount of fence needed is the perimeter of the fence. The amount of fence needed is 127.1ft

From the diagram of the fence, we have:

[tex]r = 15[/tex] ---- the radius

[tex]l = 40ft[/tex] -- the length of the parallel lines

First, we calculate the length of the arc surrounding the half circle

This is calculated using:

[tex]L = \frac{\theta}{360} \times 2\pi r[/tex]

Because it is a half circle

[tex]\theta = 180[/tex]

So, we have:

[tex]L = \frac{\180}{360} \times 2 \times 3.142 \times 15[/tex]

[tex]L =0.5 \times 2 \times 3.142 \times 15[/tex]

[tex]L =47.13[/tex]

The amount of fence needed is the sum of the length of parallel lines and the semicircle.

So, we have:

[tex]Amount = L + l + l[/tex]

[tex]Amount =47.13 + 40 + 40[/tex]

[tex]Amount =127.13[/tex]

Approximate

[tex]Amount =127.1[/tex]

Hence, the amount of fence needed is 127.1ft

Select three involuntary muscles:

stomach
intestinal
heart
biceps
brain

I'll give Brainliest! :D

Answers

Answers:

A) stomachB) intestinalC) heart

=============================================

Explanation:

The stomach muscle helps digest food. The muscle isn't something a person can control at will. Instead, the body handles it automatically. This is why choice A is one of the answers.

The intestinal muscles work in a similar fashion to help pass nutrients into the blood stream and also pass waste out of the body. All of these processes are done automatically and you don't have to think about them. They just happen. Therefore, choice B is another answer.

Another example of an automatic or involuntary muscle doing its own thing is the heart muscle. It continuously pumps blood to help distribute nutrients and oxygen, and also dump waste byproducts (eg: carbon dioxide) out of the body. So choice C is the third and final answer.

An example of a muscle that's voluntary are the biceps. You can flex these muscles, and move them around at will. For example, when you pick up an item. So this allows us to rule out choice D.

I'm not sure why your teacher listed "brain". It has properties related to muscles such as the idea of practicing a topic to help retain it (similar to exercising to stay in shape); however, the brain itself isn't a muscle on a technical biological level.

--------------------

Extra info:

Some more involuntary muscles are:

The diaphragm muscle to help the lungs expand and contract (to breathe in oxygen or exhale carbon dioxide).The muscles that allow your eyes to blink. The technical name for them isn't coming to mind at the moment. These muscles blink at some fairly random yet consistent rate, and also blink whenever something like dust particles enter the eye (or threaten to).At some level, you could argue that the biceps are involuntary in some way. What I mean by this is that there's a reflex action to them that is automatically controlled. However, for the most part, the biceps are voluntary muscles.

A camera has a listed price of 587.99 before tax. If the sales tax rate is 7.75%, find the total cost of the camera with sales tax included.

Answers

Answer:

Total cost = 633.559225

Step-by-step explanation:

First we can calculate the tax cost for the camera: 7.75% × 587.99 = 45.569225

That is the tax sale or cost.

Then we calculate total cost by adding the listed price with the tax cost:

587.99 + 45.569225 = 633.559225

Just remember these simple equation:

Step 1: Tax Cost = Tax Percentage × Listed Price

Step 2: Total cost = Tax Cost + Listed Price (original price)

HELPPPP ASAPPP! 100 POINTS + BRAINILEST!!!!!!Read the Passage, and answer the 3 questions with small explanations! Thanks! :)(SUPER EASY IF YOU READ THE PASSAGE)Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.QUESTIONS:1.) Which line from the text best explains the main problem with recalling details of a scene or room?
