5-6. Brianna is a technician at a radio station. She knows that, unlike many other types of waves, radio waves can be very long. Below is the graph for a radio wave that is 1 meter in length.
Here is the function of the radio wave: f(x) = sin (21x)
Graph the function
Write down the amplitude, period, and frequency.
The amplitude is 1
The period is 2
The frequency is 1/2

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
