What does “period” do or mean when graphing a periodic function?

1 answer:

5 0

Hello!

A period of a function like the sin graph or cosine graph are periodic because they repeat themselves on a interval and never end and each interval from trough to trough or peak to peak is called one period. Or another way if looking at it is one period is the time for one complete cycle of motion before it repeats itself.

Hope this helps thanks.

Matt needs to swim 8 meters in 25 seconds yo qualify as a state swimer. Which unit rate describes the speed Matt needs to swim

fiasKO [112]

Answer:

Option D, 0.32 meters per second

Step-by-step explanation:

Step 1: Find the unit rate at which Matt needs to swim

Make an equation to represent the scenario.

25m = 8

Step 2: Solve for m by dividing both sides by 25

25m / 25 = 8 / 25

m = 0.32

Step 3: Check

To check, you can multiply the number of second, 25, by the meters per second to see if you get the total meters, 8.

0.32 * 25

8

So, the answer is correct :)

0.32 means that Matt needs to swim 0.32 meters per second to qualify as a state swimmer.

Answer: Option D, 0.32 meters per second
