(a)
or 
(b)
or
Step-by-step explanation:
Given
--- North Dakota
--- Cheyenne, Wyoming
Solving (a): Inequality to compare both temperatures
From the given temperatures, we can conclude that:
or 
Because
i.e. 1 is greater than -2
or
i.e. -2 is less than 1
Solving (b): Inequality to compare the absolute values of the temperatures
We have:


The absolute values are:




By comparison:
or 
Because
i.e. 2 is greater than 1
or
i.e. 1 is less than 2

Answer:
Total impedance in circuit = 8 - 2j ohms
Step-by-step explanation:
Given:
Circuit one = 1 + 3j ohms
Circuit two = 7 - 5j ohms
Find:
Total impedance in circuit
Computation:
Total impedance in circuit = Circuit one + Circuit two
Total impedance in circuit = 1 + 3j + 7 - 5j
Total impedance in circuit = 8 - 2j ohms
