Se generan ondas, introduciendo en agua el borde de una regla 15 veces en 3.0 segundos. Calcular: a) el periodo de las ondas b) su frecuencia

Answers

Answer 1

Answer:

Ver explicacion

Step-by-step explanation:

La frecuencia de una onda se define como el número de ciclos completos que realiza una partícula en un segundo.

f = n / t = 15 ciclos / 3 segundos = 5 ciclos por segundo o Hertz

El período de una onda es el tiempo que tarda la onda en realizar una oscilación o ciclo completo.

T = t / n = 3/15 = 0,2 segundos

Sophie used the equation y = x + 1 to represent that the length of a piece of fabric needed for a craft project (y) is always 1 inch greater than the length of the object made with the fabric (x). Which graph represents four solutions to Sophie's equation?

Answers

Answer: Last graph, the one with the points (1, 2), (2, 3), (3, 4), and (4, 5)

Step-by-step explanation:

We have the equation y = x + 1

Now we can replace x by different values to get pairs (x, y).

if x = 1, we have:

y = 1 + 1 = 2

then we have the pair (1, 2)

if we have x = 2, then:

y = 2 + 1 = 3

Then we have the pair (2, 3)

So we need to find the graph that has these points.

The only graph that has the points (1, 2) and (2, 3) is the last graph.

A stack of one dozen cookies of diameter
5 in. exactly fits in a cylindrical container of
volume 179.715 in.3. Which is the thickness of
each cookie?

Answers

Answer:

.763 in for each cookie

Step-by-step explanation:

[tex]179.715 =\pi (2.5)^{2} h\\179.715= \pi (6.25)h\\179.715=19.635h\\h=9.153\\[/tex]

After you solve for the height you would divide it by 12 to get the thickness of one cookie which is .763 in.

Answer:

Subtract 5x from both sides of the equation.

7y=1−5x

x+4y=−5

Divide each term by 7 and simplify.

y=17−5x/7

x+4y=−5

Subtract x from both sides of the equation.

y=1/7−5x/7

4y=−5−x

y=1/7−5x/7

Divide each term by 4 and simplify.

y=1/7−5x/7

y=−5/4−x/4

What is a matrix?

A matrix is an array of values arranged in rows and columns, such that they are used to represent a mathematical object.

Matrices are associative when they are multiplied. This means that any two adjacent matrices can be multiplied first and then the third one can be multiplied. This would yield the same answer. This means that equation A is true. In equation B, different matrices are multiplied and added. Therefore, the LHS is not equal to the RHS. In equation C, the order in which the matrices are written and multiplied is different. Matrices aren't commutative with multiplication. Therefore, the LHS is not equal to the RHS. Similarly, equation D is also wrong.

Thus, we have found that among the given equations, equation A is true.

Answers

Answer:

a. y = 3x + 4.5 & y = 7x + 2

b. x = 0.625 (year)

c. 6.375 feet

Explanation:

Type A starts at 4.5 and Type B starts at 2 ,each year can be marked as x

type A grow 3 inches per year = 3x

type B grows 7 inches per year = 7x

y = the total height

Since they both equal to y, you can set them equal to each other

3x + 4.5 = 7x +2

After solve you get answer for b

Work:  3x + 4.5 = 7x + 2

              4.5 = 4x + 2

               2.5 = 4x

              0.625 = x

Substitute the value of x you got from part b into each equation then you will get 6.375 as your y value which is also your height

(PLEASE) Triangle IJK is similar to triangle LMN. Find the measure of side MN. Round your answer to the nearest tenth if necessary. Figures are not drawn to scale.

Answers

Answer:

MN = 126.31

Step-by-step explanation:

ΔIJK = ΔLMN --- (given)

So,-----------------------

KI / KJ = NL / MN

19 / 40 = 60 / MN

MN = 60 × 40 / 19

MN = 126.31

The required measure of side MN will be 126.3 units.

What are Similar Triangles?

Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides. The triangles that like one another but may not be exactly the same size are said to be similar triangles.

Given that triangle ΔIJK ~ ΔLMN in the question.

We know that Similar triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.

As per the similarity rule of triangles, we can write the ratio as:

⇒ KI / KJ = NL / MN

⇒ 19 / 40 = 60 / MN

⇒ MN = 60 × 40 / 19

⇒ MN = 126.3157

Rounded to the nearest tenth to get

⇒ MN = 126.3

A trapezoid with an area of 36 inches squared.

What is the area of the enlarged trapezoid?
54 in.²
81 in.²
576 in.²
864 in.²

Answers

Answer:

B. 81 in.²

Step-by-step explanation:

We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5. We are asked to find the area of the enlarged trapezoid.

The area of the original trapezoid is 36 square inches.

Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.

The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.

1.5 × 1.5 = 2.25

Area of new trapezoid: 2.25 × 36 in²

Area of new trapezoid = 81 in²

The area of the enlarged trapezoid would be 81 in² or option B.

The answer is b. 81 in.²

Find the tangent of angle U.
A) 48/55
B) 48/73
C) 55/48
D) 55/73

Answers

Answer:

C. 55/48

Step-by-step explanation:

perpendicular (p) = 55

base (b) = 48

Tangent < U = p /b = 55 /48

In triangle TUV, the tangent of angle U would be tan U = 55/58. Hence option C is true.

Used the formula of the tangent of an angle that states,

Tan θ = Opposite / Base

Given that,

A triangle TUV is shown in the image.

Now by definition of the tangent of an angle,

tan U = TV/UV

Substitute TV = 55 , UV = 48;

tan U = 55/58

Therefore, Option C is true.
