13.5/3 = 4.5
He hiked for 4.5 hours.
Express √3 + i in polar form:
|√3 + i| = √((√3)² + 1²) = √4 = 2
arg(√3 + i) = arctan(1/√3) = π/6
Then
√3 + i = 2 (cos(π/6) + i sin(π/6))
By DeMoivre's theorem,
(√3 + i)³ = (2 (cos(π/6) + i sin(π/6)))³
… = 2³ (cos(3 • π/6) + i sin(3 • π/6))
… = 8 (cos(π/2) + i sin(π/2))
… = 8i
Answer:
x =8
Step-by-step explanation:
-5(x-3)= -25
we apply distributive property
-5*x +5*3 =-25
-5x +15= -25
-5x = -25-15
-5x = -40
x = 40/5
x =8
1. The answer would be RS. 2. The matching angle would be T.
