Answer:
The formula for period is T = 1 / f , where "T" is period – the time it takes for one cycle to complete, and "f" is frequency.
To get period from frequency, first convert frequency from Hertz to 1/s.
Now divide 1 by the frequency. The result will be time (period) expressed in seconds.
Answer:
40
Step-by-step explanation:
5 x 5 is 25 so 2 x 5, 20 times makes 40
Answer:
C.
Step-by-step explanation:
The minus sign (of the multiplier -1/3) changes the direction of z by 180°. The magnitude of the multiplier 1/3 reduces the magnitude of the product to 1/3 that of z. The graph that has these characteristics is graph C.
