Answer:
48 +j64 ohms
Step-by-step explanation:
The impedance of a series circuit is the sum ...
R + jXl -jXc
= 48 +j100 -j36
= 48 +j64 . . . . ohms

"j" is the electrical engineer's name for √-1, because "i" is used to represent current.
Answer:
25) 3 = 5 + secΘ where we have 2 possible values of Θ (2π/3 or 4π/3)
<em>3 = 5 + sec (2π/3)</em>
<em>3 = 5 + sec (120 degrees)</em>
<em>3 = 5 + (-2)</em>
<em>3 = 3</em>
theta = 4π/3
<em>3 = 5 + sec (240 degrees)</em>
<em>3 = 5 + (-2)</em>
<em>3 = 3</em>
Therefore, the equation is true for both 2π/3 and 4π/3
27) -2 SinΘ = -1 {π/6 , 5π/6}
<em>-2 * sin(π/6) = -1 </em>
<em>sin(π/6) = 1/2</em>
1/2 = 1/2
LHS = RHS
theta = 5π/6
<em>-2 sin(5π/6) = -1 </em>
<em>sin(5π/6) = 1/2 </em>
1/2 = 1/2
LHS = RHS
