Answer:

D

Step-by-step explanation:

I is true. Limits don't care if the point defined or not. All they care about is if they are approaching a value from both sides, unequivocally.

II is not true. We need more information about the type of function.

III is true. Since the point isn't defined but the limit exist, we have a removable discontinuity

Answer 80

Step-by-step explanation:

If the line is a straight line through two parallel lines then the angles of the two intersections should be the same. Basically because they are both on the bottom right they will be the same.

The value of 'y' is 80 degrees. option B

Note that alternate angles are equal

The intersections of a transversal with two parallel lines forms various types of pairs of angles such as

In this case, the transverse line forms alternate angles of line c and b

Angle at line c = 80 degrees

Angle at line b = y

Since they are alternate angles, y = 80 degrees

Therefore, the value of 'y' is 80 degrees. option B

Answer:

True

Step-by-step explanation:

y = -2x + 9 is already in slope-intercept form, so we can leave it be. 8x + 4y = 28, however, is not, so we have to convert it to find the answer.

To do this we have to separate the variable 4y from the rest.

We get 4y = -8x + 28.

But, y must equal zero, so to achieve this, we divide the entire equation by 4.

Then we get y = -2x + 7

Since the slopes are the same (-2x = -2x) the lines are parallel.

The expression sin2x is a trigonometric expression

The equivalent of sin2x is (d) 2sinxcosx

The expression is given as:

sin2x

Rewrite properly as:

sin(2x)

To solve the expression, we make use of the following double angle ratio

sin(2a) = 2sin(a)cos(a)

Substitute x for a in the above equation

sin(2x) = 2sin(x)cos(x)

Rewrite the equation as

sin2x = 2sinxcosx

Hence, the equivalent of sin2x is (d) 2sinxcosx

Answer:

1) La piedra permanece en el aire en 4 segundos.

2) La piedra alcanza una distancia horizontal de 32 metros.

3) La velocidad de la piedra con la que alcanza el suelo es aproximadamente 40.792 metros por segundo.

Step-by-step explanation:

El problema nos indica un caso de tipo parabólico, el cual consiste en la suma de un movimiento horizontal a velocidad y un movimiento uniforme acelerado por la gravedad desde el reposo.

1) El tiempo total que la piedra permanecería en el aire es tiempo requerido entre la parte superior del acantilado y el fondo. La ecuación cinemática que vamos a utilizar es la siguiente:

[tex]y = y_{o} + v_{o,y}\cdot t +\frac{1}{2}\cdot g \cdot t^{2}[/tex] (Ec. 1)

Donde:

[tex]y_{o}[/tex] - Altura inicial, medida en metros.

[tex]y[/tex] - Altura final, medida en metros.

[tex]v_{o,y}[/tex] - Velocidad vertical inicial de la piedra, meadida en metros por segundo.

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

[tex]t[/tex] - Tiempo, medido en segundos.

Si sabemos que [tex]y_{o} = 80\,m[/tex], [tex]v_{o,y} = 0\,\frac{m}{s}[/tex] y [tex]g = -10\,\frac{m}{s^{2}}[/tex], entonces encontramos la siguiente función cuadrática:

[tex]-5\cdot t^{2}+80 = 0[/tex] (Ec. 2)

El tiempo en el que la piedra permanece en el aire es:

[tex]t = 4\,s[/tex]

La piedra permanece en el aire en 4 segundos.

2) La distancia horizontal es descrita por la siguiente fórmula cinemática:

[tex]x = x_{o}+v_{o,x}\cdot t[/tex] (Ec. 3)

Donde:

[tex]x_{o}[/tex] - Posición horizontal inicial, medido en metros.

[tex]x[/tex] - Posición horizontal final, medido en metros.

[tex]v_{o,x}[/tex] - Velocidad horizontal inicial de la piedra, medida en metros por segundo.

Si sabemos que [tex]x_{o} = 0\,m[/tex], [tex]v_{o,x} = 8\,\frac{m}{s}[/tex] and [tex]t = 4\,s[/tex], entonces la distancia horizontal alcanzada por la piedra es:

[tex]x = 0\,m + \left(8\,\frac{m}{s}\right)\cdot (4\,s)[/tex]

[tex]x = 32\,m[/tex]

La piedra alcanza una distancia horizontal de 32 metros.

3) En primer lugar, determinamos los componentes vertical y horizontal de la velocidad final de la piedra por medio de las siguientes fórmulas cinemáticas:

Velocidad final horizontal ([tex]v_{x}[/tex]), medida en metros por segundo.

[tex]v_{x} = \frac{x-x_{o}}{t}[/tex] (Ec. 4)

Velocidad final vertical ([tex]v_{y}[/tex]), medida en metros por segundo.

[tex]v_{y} = v_{o,y}+g\cdot t[/tex] (Ec. 5)

Si [tex]x = 32\,m[/tex], [tex]x_{o} = 0\,m[/tex]. [tex]t = 4\,s[/tex], [tex]v_{o,y} = 0\,\frac{m}{s}[/tex] y  [tex]g = -10\,\frac{m}{s^{2}}[/tex], los componentes de la velocidad final de la piedra son:

[tex]v_{x} = \frac{32\,m-0\,m}{4\,s}[/tex]

[tex]v_{x} = 8\,\frac{m}{s}[/tex]

[tex]v_{y} = 0\,\frac{m}{s}+\left(-10\,\frac{m}{s^{2}} \right) \cdot (4\,s)[/tex]

[tex]v_{y} = -40\,\frac{m}{s}[/tex]

Por último, determinamos la velocidad final de la piedra por Teorema de Pitágoras:

[tex]v = \sqrt{v_{x}^{2}+v_{y}^{2}}[/tex] (Ec. 6)

[tex]v = \sqrt{\left(8\,\frac{m}{s} \right)^{2}+\left(-40\,\frac{m}{s} \right)^{2}}[/tex]

[tex]v \approx 40.792\,\frac{m}{s}[/tex]

La velocidad de la piedra con la que alcanza el suelo es aproximadamente 40.792 metros por segundo.

Answer:

28 m

Step-by-step explanation:

Length = x

90 = 2(17 + x)

17 + x = 90/2 = 45

so

x = 45 - 17 = 28 m

Step-by-step explanation:

x - the part

3x one part(first number)

4x second part (second number)

so u have

3x + 4x = 1001

7x= 1001

x = 1001/7

x= 143. First number : 3x = 3• 143 = 429

Second number : 4x = 4• 143= 572

So, 429 and 572 are the numbers

Step-by-step explanation:

An Egyptian fraction is the sum of distinct unit fractions. Here, we're asked to decompose 1/3 into an Egyptian fraction sum of two fractions. There are formulas available when the sum has a numerator value of 2.

Here, the sum is a unit fraction. A reasonable approach is to use 1/(n+1) as the larger portion of 1/n. Then the other portion is 1/(n(n+1)). That is effectively what we end up with here.

Multiplying by 3AB gives ...

  AB = 3B +3A

Solving for B, we find ...

  AB -3B = 3A

  B(A -3) = 3A

  B = 3A/(A -3)

In order for A-3 to be a factor of A, or equal to 3, we must have ...

  A-3 = 1  ⇒  A = 4

  A-3 = 3  ⇒  A = 6

  A-3 = 3×3  ⇒  A = 4×3

This will give integer values for B when A is one of 4, 6, or 12. In the case of A=6, the two fractions are equal, which is not what you want

The two solutions are ...

  (A, B) = (4, 12) or (12, 4)
