Total impedance of circuit is Z1 + Z2
Here it is important that real numbers we sum with real numbers and complex numbers with complex numbers
Let Zs represent total impedance.
Zs = Z1 + Z2 = 3 + 4i + 5 - 2i = 3 + 5 + 4i - 2i = 8 + 2i
Answer is :
8+2i
Answer:
The number of years to double the lump sum in value is;
N = 72/10 = 7.20
N = 7.20 years
Step-by-step explanation:
Using the rule of 72 for the approximation:
The formula for rule of 72 is;
Number of years to double = 72/interest rate in percentage
Given;
Interest rate = 10%
The number of years to double the lump sum in value is;
N = 72/10 = 7.20
N = 7.20 years
18 chocolate cakes were made. 40(3)= 120 cakes in total. 15%=.15 .15(120)= 18
Slope =2/3
70,80) (10,40)
(80-40)/(70-10) = 40/60
4/6
2/3
