If z=3−5i, find |z|.
geniusboy [140]

Answer:

Step-by-step explanation:

The absolute value of z is the distance between the point graphed from the complex number and the origin on a complex plane.  In a complex plane, the x axis is replaced by R, real numbers, and the y axis is replaced by i, the complex part of the complex number.  Our real number is positive 3 and the complex number is -5, so we go to the right 3 and then down 5 and make a point.  Connect that point to the origin and then connect the point to the x axis at 3 to construct a right triangle that has a base of 3 and a length of -5.  To find the distance of the point to the origin is to find the length of the hypotenuse of that right triangle using Pythagorean's Theorem.  Therefore:

|z|=\sqrt{(3)^2+(-5)^2} and

|z|=\sqrt{9+25} and

|z|=\sqrt{34}

I am confused on how to set this question up. Can someone please help me?
gregori [183]

Answer:

Step-by-step explanation:

Comparing triangle EGD and triangle ELA

AL/DG = EL/EG

AL = x, DG = 3, EL = 5+5+5+5= 20

EG = 5

x/3 = 20/5

x/3 = 4

x = 3×4

x = 12

ANYEONESSSSSSSSSS???
Dmitriy789 [7]

Answer:

C. 2

Step-by-step explanation:

To solve slope, the formula is \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }. 9-3 is 6 and 5-2 is 3. So simplify 6/3 to 2.

Hope it's correct!
