determine the period. (1,-7) (11,-7) enter
Answer
Explanation:
Step1: Identify key - points on wave
The wave repeats its pattern. The two given points $(1, - 7)$ and $(11,-7)$ are corresponding points on the wave.
Step2: Calculate the period
The period $T$ is the horizontal distance between two corresponding points on a periodic wave. So, $T=11 - 1$. $T = 10$
Answer:
10
