Find the average rate of change.
alina1380 [7]

The average rate of change = 1.59 ≈ 2

The average rate of change can be calculated by

1) The first one = \frac{3 + 0}{2} = 1.5

2 ) the second can also be solved by ; 8 + 2/ 2 = 5

3 ) the third one will be 20 + 6 / 2 = 13

4) 8.5

5) 12.5

To calculate the average rate of change

we will first add all the distance

Adding all the distance we will get the sum = 3 + 8 + 20 + 10 + 10 = 51

The total time = 2 + 6 + 9 +15 = 32

Thus the average rate of change = 51 / 32 = 1.59

PLS HELP!<br> What is the frequency of the sinusoidal graph?
docker41 [41]

the frequency of the sinusoidal graph is 2 in 2 π interval

Step-by-step explanation:

The frequency of the graphs refers to the number of the cycles, the graph completes in a given fixed interval.  

We already know the formula that  

         P= (1/ F)

Thus, F= (1/ P)

Where F= frequency and P= Period

Period is the horizontal length (x- axis component) of one complete cycle.

Thus, Observing the above graph

We find that the graph completes 1 cycle in π interval and 2 cycles in 2π interval

Thus, the frequency of the sinusoidal graph is 2 in 2 π interval
