Answer:
6 × 1/4 = 4
4 × 1/4 = 1
4 ÷ 1/4 = 16
All three of these are correct
Step-by-step explanation:
16 × 1/4 = 4
16/4 = 4
4 = 4
1/4 ÷ 4 = 116
1/4 × 1/4 = 116
1/16 ≠ 116
4 x 1/4 = 1
4/4 = 1
1 = 1
4 ÷ 1/4 = 16
4 × 4 = 16
16 = 16
Current balance - 12 months a year times the monthly fee
=75-12(12.50)
=75-150
=-75
She will have negative $75 so she will be below zero.
Answer:
a. cosθ = ¹/₂[e^jθ + e^(-jθ)] b. sinθ = ¹/₂[e^jθ - e^(-jθ)]
Step-by-step explanation:
a.We know that
e^jθ = cosθ + jsinθ and
e^(-jθ) = cosθ - jsinθ
Adding both equations, we have
e^jθ = cosθ + jsinθ
+
e^(-jθ) = cosθ - jsinθ
e^jθ + e^(-jθ) = cosθ + cosθ + jsinθ - jsinθ
Simplifying, we have
e^jθ + e^(-jθ) = 2cosθ
dividing through by 2 we have
cosθ = ¹/₂[e^jθ + e^(-jθ)]
b. We know that
e^jθ = cosθ + jsinθ and
e^(-jθ) = cosθ - jsinθ
Subtracting both equations, we have
e^jθ = cosθ + jsinθ
-
e^(-jθ) = cosθ - jsinθ
e^jθ + e^(-jθ) = cosθ - cosθ + jsinθ - (-jsinθ)
Simplifying, we have
e^jθ - e^(-jθ) = 2jsinθ
dividing through by 2 we have
sinθ = ¹/₂[e^jθ - e^(-jθ)]
