#4.)
1/4 + 3/8 + 1/2 + 5/8 + 3/4
Answer:
A
Step-by-step explanation:
The equation y =1, means that y is one for any value of x. Therefore you will get a straight horizontal line that goes through (-1,1) (0,1), (1,1), (2, 1) etc.. It will be parallel to the y-axis, but one unit up, as I have tried to illustrate below:

Phase angle (∅) in a parallel RL circuit is given by the formula; tan∅ 
where
is current through the inductor and given by 
and
is current through the resistor and given by 
hence, tan∅
or ∅ = 26.565 degree
