Answer:
20,950.12
Step-by-step explanation:
use the formula A=P(1-r/100)^n,P=30000,r=5%,,n=7
y=3÷9
2x-9y=11
or,2×7-9y=11
or,14-11=9y
or,3÷9=y
Solution:
Given: zj = 3- j2, zz = - 4 + j3
Part a:
zj = 3- j2 =
zz = - 4 + j3 =
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 =
