Answer:

46.9333 feet per second

Step-by-step explanation:

Answer:

The wire is about 18.44 feet long.

Step-by-step explanation:

From the question:

The wire is √340 feet long.

This implies that the length of the wire is √340 feet.

Converting the value of this length (√340) to decimal gives;

√340 = 18.439

Now, let's convert 18.439 to the nearest hundredth of a foot.

18.439 ≅ 18.44

Therefore, the length of the wire to the nearest hundredth of a foot is 18.44 feet.

In other words, the wire is about 18.44 feet long.

Answer: 1,4,5

Step-by-step explanation:

The correct options are, The simplified expression for g(f(x)) is x.

The functions are not inverses of each other.

First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.

We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.

Given, f(x) = 1/(8x³).

f(x) = 1/(2x)³.

y = 1/(2x)³.

(2x)³ = 1/y.

[tex]2x = \frac{1}{y^\frac{1}{3}}[/tex].

[tex]x = \frac{1}{2y^\frac{1}{3}}[/tex].

[tex]f^{-1}(x) = \frac{1}{2x^\frac{1}{3}}[/tex] and g(x) = [tex]2x^\frac{1}{3}[/tex] so, they are not inverses of each other.

Now, f(g(x)) = [tex]\frac{1}{8((2x)^\frac{1}{3})^3}[/tex].

f(g(x)) = 1/16x.

g(f(x)) = [tex]2(1/8x^3)^\frac{1}{3}[/tex].

g(f(x)) = x

Answer:

AC = 25

Step-by-step explanation:

Since B is on the segment AC, then

AC = AB + BC, substitute values

5x = 2x +10 + x , that is

5x = 3x + 10 ( subtract 3x from both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Thus

AC = 5x = 5(5) = 25

(92-1512)=17

Answer:

A. 12 and 43

Step-by-step explanation:

Pythagorean theorem is given as = [tex] a^2 + b^2 = c^2 [/tex]

Where, a and b are the two legs of the right triangle, while c is the hypotenuse/longest leg of the triangle.

In the figure given, the side of the largest square = the hypotenuse of the triangle = c

While the side of the other squares = a and b respectively, of the triangle.

Area of square = s², where s is the side length of the square.

Since we are given that the area of the largest square = 55, this is also equivalent to c² in the Pythagorean theorem.

The side length of the largest square = √55 ≈ 7.4 = c

Therefore, to determine the area of the other squares, check the options given if they add up to give 55.

Option A: 12 + 43 = 55

Option B: 14 + 40 = 54

Option C : 16 + 37 = 53.

The correct possible areas of the smaller squares would be A. 12 and 43.

Answer:

María solamente debe venderle al cliente 10 unidades

Step-by-step explanation:

Explicación paso a paso:

Una docena representa un total de doce (12) unidades. Los huevos se empacan por docena, por lo tanto si nos piden solo 5/6 de la docena, multiplicamos dicha fracción por 12 unidades:

5/6 · 12 = (12 · 5)/6 = 60/6 = 10 unidades

Por lo tanto, María solamente debe venderle al cliente 10 unidades, es decir 5/6 representa 10 unidades de los huevos

Usando conceptos de proporción, se encuentra que Martha debe vender 10 huevos al cliente.

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

1 docena - 12 huevos

5/6 de docena - x huevos

Aplicando multiplicación cruzada:

[tex]x = 12 \times \frac{5}{6} = \frac{12 \times 5}{6} = 2 \times 5 = 10[/tex]

Martha debe vender 10 huevos.

Answer:

-26 or 14

Step-by-step explanation:

Given that

Coordinate of point A is -6.

Length of AB = 20

To find:

Coordinates for the point B = ?

Solution:

We are given that:

AB = 20

In other words, we can use modulus function to define the distance between A and B:

|Coordinates of B - Coordinates of A| = 20

Let the coordinates of B = [tex]x[/tex]

Kindly refer to the attached image for the given situation.

Point B might be either on the left or on the right side of A.

That means:

[tex]|x-(-6)| = 20\\\Rightarrow |x+6|=20[/tex]

Now, let us have a look at the modulus function:

[tex]|y|=\left \{ {-{y}\ if\ y<0 \atop {y}\ if\ y>0} \right.[/tex]

So,

[tex]|x+6|=\left \{ {-{(x+6)}\ if\ (x+6)<0 \atop {(x+6)}\ if\ (x+6)>0} \right.[/tex]

[tex](x+6 ) =20\\\Rightarrow x =14[/tex]

[tex]-(x+6 ) =20\\\Rightarrow x =-26[/tex]

Therefore, the answer is:

-26 or 14
