the function f of x equals negative (x - 3 in the presidency squared plus sine can be used to represent the area of a rectangle with a perimeter of 12 units as a function of the length of the rectangle x what is the maximum area of the rectangle​

Answer:

x = 6

Step-by-step explanation:

7x - 2 = 40

7x - 2 + 2 = 7x

40 + 2 = 42

7x = 42

7x / 7 = x

42 / 7 = 6

x = 6

30+2*75=

...

180

Answer:

30 + 2x = 180

Step-by-step explanation:

This is becuase we know this triangle is an isosceles triangle. (The two markings on the sides prove that.) An isosceles triangle is when two sides (so naturally also two angles) are the same. This means the other angle is x. We know that if we add all of the angles, we'll get 180. So, 30 + x + x = 180 or "30 + 2x = 180".

Also, x = 75.

Here:

30 + 2x = 180

30 - 30 + 2x = 180 - 30

2x = 150

2x / 2 = 150 / 2

x = 75

Answer:

[tex]Longer\ leg = 8[/tex]

Step-by-step explanation:

Given

30-60-90 triangle

[tex]Shorter = \frac{8}{\sqrt 3}[/tex]

Required

The longer leg

The following relationship exists in a 30-60-90 triangle.

[tex]Longer\ leg = \sqrt 3 * Shorter\ Leg[/tex]

This gives:

[tex]Longer\ leg = \sqrt 3 * \frac{8}{\sqrt 3}[/tex]

[tex]Longer\ leg = 1* \frac{8}{1}[/tex]

[tex]Longer\ leg = 1* 8[/tex]

[tex]Longer\ leg = 8[/tex]

Answer:

  y = x + 4

Step-by-step explanation:

Since x > 5, x-3 > 0, x + 2 > 0 and x - 5 > 0

So Ix - 3I = x - 3,   Ix + 2I = x + 2   and x - 5 = x - 5

Therefore, y = x - 3 + x + 2 - x + 5

                  y = x + 4

Answer:

Step-by-step explanation:

It might interest you to know what this question means without the restriction. See graph 36b. This shows exactly what happens to the absolute value. There are all sorts of turns and twists in it. Notice all the changes in direction and the minimum at -2,-2. The y intercept is at 0,0.

0,0 is also one of the x intercepts as well. The other is -4,0. The whole point of showing you this is to make you aware of what the restriction does.

The graph is reduced to a line starting at (5,9)

Answer:

1) La velocidad de la bala después de atravesar el muro es de aproximadamente 435,890 metros por segundo.

2) La potencia del automóvil es 96438,272 watts o 131,208 caballos de vapor.

3) La velocidad del objeto al llegar al suelo es aproximadamente 14,005 metros por segundo.

Step-by-step explanation:

1) La velocidad final de la bala puede determinarse mediante el Teorema del Trabajo y la Energía, a partir del cual se tiene la siguiente fórmula:

[tex]\frac{1}{2}\cdot m\cdot v_{o}^{2} -F\cdot \Delta s = \frac{1}{2}\cdot m \cdot v_{f}^{2}[/tex] (1)

Where:

[tex]m[/tex] - Masa de la bala, en kilogramos.

[tex]v_{o}, v_{f}[/tex] - Velocidades inicial y final de la bala, en metros por segundo.

[tex]F[/tex] - Resistencia del muro al avance de la bala, en newtons.

[tex]\Delta s[/tex] - Espesor del muro, en metros.

Si sabemos que [tex]m = 0,01\,kg[/tex], [tex]v_{o} = 500\,\frac{m}{s}[/tex], [tex]F = 3000\,N[/tex] and [tex]\Delta s = 0,1\,m[/tex], entonces la velocidad final de la bala es:

[tex]v_{f}^{2}=v_{o}^{2} -\frac{2\cdot F\cdot \Delta s}{m}[/tex]

[tex]v_{f} = \sqrt{v_{o}^{2}-\frac{2\cdot F\cdot \Delta s}{m} }[/tex]

[tex]v_{f} \approx 435,890\,\frac{m}{s}[/tex]

La velocidad de la bala después de atravesar el muro es de aproximadamente 435,890 metros por segundo.

2) Asumamos que el automóvil acelera a tasa constante, significando que la fuerza neta será constante. Para un sistema cuya fuerza neta sea constante, la potencia experimentada queda descrita por la siguiente ecuación:

[tex]P = m\cdot a(t)\cdot v(t)[/tex] (2)

[tex]a(t) = a[/tex] (3)

[tex]v(t) = v_{o} + a\cdot t[/tex] (4)

Donde:

[tex]P[/tex] - Potencia, en watts.

[tex]m[/tex] - Masa del automóvil, en kilogramos.

[tex]a(t)[/tex] - Aceleración, en metros por segundo al cuadrado.

[tex]v(t)[/tex] - Velocidad, en metros por segundo.

[tex]v_{o}[/tex] - Velocidad inicial del automóvil, en metros por segundo.

Si sabemos que [tex]m = 1000\,kg[/tex], [tex]a = 3,472\,\frac{m}{s}[/tex], [tex]v_{o} = 0\,\frac{m}{s}[/tex] y [tex]t = 8\,s[/tex] entonces la potencia experimentada por el automóvil es:

[tex]P = 96438,272\,W[/tex] ([tex]131,208\,C.V.[/tex])

La potencia del automóvil es 96438,272 watts o 131,208 caballos de vapor.

3) El cuerpo experimenta un Movimiento de Caída Libre, el cual es un Movimiento Uniformemente Acelerado debido a la gravedad terrestre. La velocidad del cuerpo al llegar al suelo se determina mediante la siguiente fórmula cinemática:

[tex]v_{f} = \sqrt{v_{o}^{2}+2\cdot g\cdot h}[/tex] (5)

Donde:

[tex]v_{o}[/tex] - Velocidad inicial del cuerpo, en metros por segundo.

[tex]v_{f}[/tex] - Velocidad final del cuerpo, en metros por segundo.

[tex]g[/tex] - Aceleración gravitacional, en metros por segundo al cuadrado.

[tex]h[/tex] - Altura recorrida por el cuerpo, en metros.

Si sabemos que [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]g = 9,807\,\frac{m}{s^{2}}[/tex] y [tex]h = 10\,m[/tex], entonces la velocidad al llegar al suelo es:

[tex]v_{f} \approx 14,005\,\frac{m}{s}[/tex]

La velocidad del objeto al llegar al suelo es aproximadamente 14,005 metros por segundo.

Answer:

9/5

Step-by-step explanation:

The common difference = 6 - 2 = 4

The age after 6 is 6 + 4 = 10 = y

The age after 14 is 14 + 4 = 18 = z

z/ y = 18/10 = 9/5

Step-by-step explanation:

1》 x + 74° = 90°

x = 90° - 74°

x = 16°

2》 x + 134° = 180°

x = 180° - 134°

x = 46°

Answer: The answer is 8 lb for $18.80

That is the answer because you have to divide in order to see which is the best buy

You have to divide $4.98 by 2lb and you will get 2.49, divide $12.25 by 5lb which equals 2.45, divide $18.80 and you will get 2.35, divide $23.70 by 10lb and you will get 2.37. So therefore you answer is C.8lb for $18.80 because 2.35 is better than the other deals.

The complete table is

d               t

5              15

Step-by-step explanation:

Here is the correct and complete question:

The total number of hours, t, that Trent has practiced his guitar after d days is modeled by the equation t = 3d.

Complete the table below.

d               t

1

3

               15

Step-by-step explanation:

For the first space, we are to determine the value of t when d is 1

From the given equation, t = 3d, put d = 1 and determine t

t = 3d

∴ t = 3(1) = 3×1

t = 3

For the second space , we are to determine the value of t when d is 3

Put d = 3 in the equation to determine t

t = 3d

∴ t= 3(3) = 3×3

t = 9

For the third space, we are to determine the value of d when t is 15.

Put t = 15 in the equation and then find d

t = 3d

∴ 15 = 3d

Divide both sides by 3

15/3 = 3d/3

5 = d

∴ d = 5

Range

Step-by-step explanation:

To obtain the difference between two extreme values (peak or highest and the bottom or lowest) value of a distribution, the statistical measure which best captures this differ ce is the RANGE. As the range is specifically used for determining the variation between the highest and lowest value of dataset.

The range is defined Mathematically as ;

Range = Maximum value - Minimum value

Hence. To obtain the difference between the maximum and least number of votes, the range is the best measure to use.
