Now examine |a + bi| and complete the definition below. the absolute value of any complex number a + bi is the from (a, b) to (0, 0) in the complex plane.

which is the absolute value of complex plane |a+ib|

Step-by-step explanation:

The absolute value of any complex number is its modulus for which we have a formula of modulus

where a and b are real numbers.

Please look at the attachement for complex plane of the given points (a,b) and (0,0)

The distance between two points and will be

Here we need to find the distance between (a,b) and (0,0)

on substituting the values in distance formula we will get

which is the absolute value of complex plane |a+ib|

the first one isdistance

the second part is... positive real

Step-by-step explanation:

got it right

just keep asking questions until you have a better understanding.

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
