You didn’t post the question. If you post the questions, I can help.
Also, I think you can search the question and find the answers… I remember doing this one.
Answer:
Ver explicacion
Step-by-step explanation:
La frecuencia de una onda se define como el número de ciclos completos que realiza una partícula en un segundo.
f = n / t = 15 ciclos / 3 segundos = 5 ciclos por segundo o Hertz
El período de una onda es el tiempo que tarda la onda en realizar una oscilación o ciclo completo.
T = t / n = 3/15 = 0,2 segundos
3)
(x/3)+(2/5)
(5x/15)+(6/15)
(5x+6)/15
4)
(2/x)+(3/7)
(14/7x)+(3x/7x)
(3x+14)/(7x)
5)
(x/2)+(1/3)+(x/4)
(6x/12)+(4/12)+(3x/12)
(9x+4)/12
Answer:
-625
Step-by-step explanation:
The magnitude gets raised to the power, and the angle gets multiplied by the power:
5(cis7pi/4)^4 = (5^4)cis(4·7π/4) = 625cis(7π) = 625cis(π) = -625
Answer:
it's C
Step-by-step explanation:
Imagine a coordinate plane. Move 5 units away, you'll end up with (-5, 2).
