Answer:

He earned for washing 30 windows this month =  $960.

Earning per window this month = $32

He earned for washing 30 windows this month =  30 *32 =$960.

Complex numbers zj and zz are given by zj = 3- j2, zz = - 4 + j3. (a) express zj and zz in polar form. (b) find lz1l by first ap
inna [77]

Solution:

Given: zj = 3- j2, zz = - 4 + j3

Part a:

zj = 3- j2 = 3.6e^{-j33.7^{\circ}}

zz = - 4 + j3 = 5e^{j143.1^{\circ}}

Part b:

|zj| = |3− j2| =  √3² +(−2)² = √13 = 3.60

|z1| =  √(3− j2)(3+ j2) = √ 13 = 3.60.

Part c:

With the help of part a:

z1z2 = 3.6e^{-j33.7^{\circ}}.5e^{j143.1^{\circ}}

Fine the two consecutive whole numbers the square root is between: √(26) & √(60)
blondinia [14]
The consecutive number = 1,2 or 7,8 not 5,8 etc

whole number = 1,6,100 

square root of 60 = 7.746

so, if you want to know two consecutive whole numbers b/w swrt of 60
that would be
