A submarine descended 500 feet below sea level

Answers

Answer 1

The submarine is at a position of -775 feet or 775 feet below sea level.

Here, we assume that the submarine was originally at the sea level, which means it was at position 0.

It then descended 500 feet below sea level. Which means it is now at a position of 500 feet below sea level. This, can be written as-

0 - 500

= -500 feet

Further, it is given that the submarine descended another 275 feet. This means that from -500 feet it further descended 275 feet. This can be written as-

-500 - 275

= -775 feet

Thus, the submarine is at a position of -775 feet or 775 feet below sea level.

Triangle B is not a rotation of triangle A because on careful observation of this two triangles, one would see that they are mirror images of each other; reflections of each other.

A mental rotation of triangle A all through the 360° shows that at no point is it seeming exactly like triangle B.

Calculate the work done when a load of 50N is lifted through a distance of 6m.​

Answers

The amount of work done when a load of 50 newton is lifted through a distance of 6m is 300 joules.

What is the amount of work done in lifting the load?

Work done is simply the energy transfer that takes place when an object is either pushed or pulled over a distance by an external force.

It is expressed as;

Work done = force × distance

Given the data in the question;

Force applied = 50N = 50kgm/s²Distance covered = 6mWork done = ?

To determine the work done, plug the given values into the above formula and solve W.

Work done = force × distance

Work done = 50kgm/s² × 6m

Work done = 50kgm²/s² × 6

Work done = 300kgm²/s²

Work done = 300J

Therefore, 300 joules is the work done in lifting the load.

Answers

The loan that was borrowed by Georgina was for a period of 9 years.

How to calculate the value?

From the information, Gregoria borrowed $2,450, to be paid back at 3.5% annual simple interest. She repays $3,221.75. The Interest will be:

= $3,221.75 - $2,450

= $771.75

Therefore, the time taken for the loan will be expressed as:

Interest = PRT/100

where P = Principal

R = Rate

T = Time.

Interest = PRT/100

771.75 = (2450 × 3.5 × T) /100

Cross multiply

8575T = 77175

Time = 77175 / 8575

Time = 9

6.Graph the function

Answers

Based on the definition of the functions, the value of x if f(x) = g(x) is 3

How to determine the value of x?

The equations of the functions are given as

f(x) = -2x + 4

g(x) = 2x - 8

It should be noted that the above equations are linear equations

From the question, we understand that the functions are equal

This means that, we have the following equation

f(x) = g(x)

Substitute the known values in the above equation

So, we have the following equation

-2x + 4 = 2x - 8

Collect the like terms in the above equation

So, we have

2x + 2x = 8 + 4

Evaluate the like terms in the above equation

So, we have

4x = 12

Divide both sides by 4

x = 3

Hence, the value of x such that the equations are equal is 3

As a result, after demonstrating that P(k) is true for any chosen value of k, we also demonstrated that P(k + 1) is true. According to the induction hypothesis, P(n) is true for all n ∈ Z+

What is mathematical induction ?

To demonstrate that the mathematical proposition P(n) holds for all natural integers n = 1, 2, 3, 4,..., one uses the mathematical induction technique. It is frequently referred to as the induction principle in mathematics. We establish that P(1) holds in order to demonstrate a result P(n) using the mathematical induction technique. If P(1) is valid, we can assume that P(k) holds for some natural number k and use this assumption to demonstrate that P(k+1) is valid. The assertion P(n) applies to all natural numbers if and only if P(k+1) holds true.

Let

P(n): 1×2 + 2×3+3×4+........+n(n+1)=[tex]\frac{n(n+1)(n+2)}{3}[/tex]

Putting n =1 we get

P(1):1×2 =2

and

[tex]\frac{1(1+1)(1+2)}{3}=\frac{1(2)(3)}{3} =2[/tex]

Therefore P(1) is true.

Let P(K) is true

So,

P(k): 1×2 + 2×3+3×4+........+k(k+1)=[tex]\frac{k(k+1)(k+2)}{3}[/tex]

Now we have to show that P(k +1 )is also true.

P(k+1): 1×2 + 2×3+3×4+........+k(k+1)+(k+1)(k+2)=[tex]\frac{k(k+1)(k+2)}{3}+ (k+1)(k+2)[/tex]

= (k+1)(k+2)[[tex]\frac{k}{3}+1[/tex]]

=[tex]\frac{(k+1)(k+2)(k+3)}{3}[/tex]

P(k + 1) follows, and it is likewise true.

As a result, after demonstrating that P(k) is true for any chosen value of k, we also demonstrated that P(k + 1) is true. According to the induction hypothesis, P(n) is true for all n ∈ Z+.

Step-by-step explanation:

Find the angle measures

The marks on the sides means the sides are the same length

That means the base angles have the same measurement

<S = <U = 54

The sum of the angles of a triangle equals 180

<S + <U + < T = 180

54 + 54 + < T =180

108 + < T =180

<T =180-108

<T = 72

Answer:

m<U = 54°

m<T = 72°

Step-by-step explanation:

According to the isosceles triangle theorem ( If two sides of a triangle are equal , then the angles opposite to these sides are also equal. ),

ST = UT

So,

m<S = m<U.

Given that,

m<S = 54°

So,

m<U = 54°

Also, we know that the sum of the interior angles of a triangle is added up to 180 degrees.

So,

m<S + m<U + m<T = 180°

54° + 54° + m<T = 180°

108° + m<T = 180°

m<T = 180° - 108°

m<T = 72°

What is meant by the term combination?A combination is an arithmetical technique for determining the number of different arrangements in a set of items in which the order of a selection is irrelevant. You can choose the items in any order in combinations. Permutations and combinations are often confused.We will employ the formula ⁿCₓ = n! / x! * (n - x)! to calculate combinations, where n is the total number of items and x represents the amount of items chosen at a time.

For the given question;

The total number of person in the pool = 11.

The number of jury selected = 3.

Thus, the combination will be ⁿCₓ.

Where, n = 11 and x = 3.

¹¹C₃ = 11!/3!(11 - 3)!

How to Interpret Transformation of a figure?

Transformation could be reflection, translation, rotation or even dilation.

Reflection can be thought of as the mirror image of a shape across a line.

Rotation is when one turns an object around a point

Translation is simply moving an object from one point to another without any change of dimension.

If we look at the given three figures in the attached image, we can see that the second image is the reflection or mirror image of the first figure.

After reflection, we can see that it is undergoes translation, which means it is moved apart from the first figure.

Seven times the sum of a number and 9
is 5

Answers

Seven times the sum of a number and 9 is 5 then the number is -58/7 .

A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, thousand, or a million. There are summations with an infinite number of terms.

We have been given that

Seven times the sum of a number and 9 is 5

Let the number is n.

let's write "the sum of a number and 9"

n + 9 .

Then, "seven times" the sum can be written as:

7 (n + 9)

This "is 5" or "is equal to 5" and can be written as:

7 (n + 9) = 5

To solve, first expand the term in parenthesis on the left side of the equation by multiplying each term in the parenthesis by

(7×n) + (7×9) = 5

7n + 63 = 5

Next, subtract 63 from each side of the equation to isolate the n term while keeping the equation balanced:

7n + 63 - 63 = 5 - 63

7n = -58

Now, divide each side of the equation by 7 to solve for n while keeping the equation balanced:

7n / 7 = -58 / 7

n = -58/7

The number is −58/7.

Hence , the number is -58/7 when a number is seven times its sum and 9 is 5.

SOMEONE HELP PLEASEa clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price, p, it can charge per shirt. In particular, historical data shows that 6000 shirts can be sold at a price of $81, while 10,000 shirts can be sold at a price of $45. Give a linear equation in the form p = mn + b that gives the price p they can change charge for n shirts. Answer: p = ____ Musical Genius: Is It Talent, or Is It Practice?by Marcia Amidon Lusted1 So your mom made both you and your brother take piano lessons. After just a few months, your brother is playing really hard pieces of music. You, on the other hand, cant seem to get out of the beginner music book. You decide that your brother just has musical talent and you dont, and that no matter how hard you practice, youll never be as good as he is. But is that really true? Or are you just looking for an excuse to stop playing the piano?2 This is an argument that musicians and scientists love to revisit: Is musical ability an innate talent, or is it just the result of practice and determination? When someone is very good at a given thing, what is it that actually makes him good? asks Dr. K. Anders Ericsson, a psychology professor at Florida State University. Ericsson led a group of researchers in one of the most important studies about talent versus practice. Ericsson believes that two people can have the same ability to do something, such as play the piano, but the one who can engage in something called deliberate practice will be the one who becomes the most proficient.3 Deliberate practice isnt just logging in so many hours of practice time, but involves setting specific goals of skills the person needs to work on, getting immediate feedback, and concentrating on technique. Ericsson and his colleagues published a 900-page book called the Cambridge Handbook of Expertise and Expert Performance, in which they say that talent is overrated. They write that expert performers are made through practice and hard work, not simply born with amazing talent. They also suggest that if people pursue something that they love, they are more likely to work hard at it and be successful. Many people avoid doing things that they dont think theyre good at. They give up and tell themselves that they just dont have the talent. Instead, what they really dont have is the desire to be really good and the dedication to regularly practice to reach their goal.4 A lot of people believe there are some inherent limits they were born with, Ericsson says. But there is surprisingly little hard evidence that anyone could attain any kind of exceptional performance without spending a lot of time perfecting it.5 In his 2008 book Outliers, author Malcolm Gladwell summed up Ericssons work and repeatedly stated that anyone could become proficient and successful in his or her fieldincluding musicif they practiced for 10,000 hours, which he called the 10,000 Hour Rule. He writes that practice isnt the thing you do once youre good, but rather, the thing you do that makes you good. Even for those people who seem to have talent to start with, this amount of practice can make the difference between being average and being elite.6 Many scientists are questioning the entire idea of talent, calling it a myth. Folk psychologythe beliefs that people have about human behavior, usually handed down over generations as well as coming from individual experienceteaches us that talents are present at birth and only certain people are born with these special abilities. But scientists have studied successful musicians and found that many of them did not show any particular signs of talent at a very early age. Those who did were usually a part of a household where a parent was musical or encouraged musical activities. A child might show interest in music, and the parent then provides the musical training that helps the child become a good musician.How does the author develop the claim that practice is important to musical ability?by describing personal experiencesby discussing the opinions of professional musiciansby providing details about a psychology professor's researchby introducing the concept of working memory capacity I need help with this practice problem solving, having trouble.It is trigonometry.
