Answer:  The correct answer is (B) (4-i).

Step-by-step explanation:  We are given to select the correct complex number that will be plotted below the real axis and to the right of the imaginary axis.

We know that a complex number can be treated as a point in XY-coordinate plane as X-axis is the real axis and Y-axis as the imaginary axis.

That is, x + iy = (x, y).

Therefore, the given points and the corresponding quadrants can be written as

2i - 5 = (-5, 2)        Quadrant II

4 - i = (4, -1)           Quadrant IV

5 + i = (5, 1)           Quadrant I

-5i   = (0, -5)          Y-axis

-2 - i = (-2, -1)        Quadrant III.

Now, the quadrant that lies below the X (real) axis and to the right of Y (imaginary) axis is Quadrant IV.

So, the correct complex number that will be plotted below the real axis and to the right of the imaginary axis is (4 - i).

Option (B) is CORRECT.

Step-by-step explanation:

6. Los valores posicionales de dígitos son;

Miles  {}     cientos       decenas      unidades

4   {}              9                5                   6

 

7. El número de cuadrados que tiene Fernando = 12

El número de cuadrados que tiene Catalina = 16

El largo y el ancho de un cuadrado son iguales, por lo tanto tenemos;

largo × ancho = Área del cuadrado

largo = ancho = lado del cuadrado

Lado del cuadrado × Lado del cuadrado = Área del cuadrado

(Lado del cuadrado) ² = Área del cuadrado

Lado del cuadrado = √ (Área del cuadrado)

Para Fernando, Área del cuadrado = 12

Lado del cuadrado para Fernando = √12 = 2 · √3 cartones

Para Catalina, Área del cuadrado = 16

Lado del cuadrado para Catalina = √16 = 4 cartones

Por tanto, Catalina podrá realizar un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

Which of the following equations best describes a square root function that is reflected across the x-axis and has a vertex of (
Minchanka [31]

Answer:

C

Step-by-step explanation:

Rather than picking, let's try to construct one from the description.

reflected over the x axis means -\sqrt{x}

the vertex is usually at (0,0), now how do we move a graph?  or in other words  translating it.

To move left and right you use \sqrt{x-h} where if you subtract h you move right and if you add h you move left.  we go from (0,0) to (-4,2).  so 0 to -4 is 4 left, so that means we add 4.

To move up and down we use \sqrt{x}+v Here if v is positive you move up and if v is negative you move down.  going from (0,0) to (-4,2) it moves up 2

So now we put them all together -\sqrt{x+4}+2  And if you look, C matches that exactly.
