38 is 95% is what number?

40

Step-by-step explanation:

let the number be 'x'

95 % of x = 38

(95 / 100)x =38

x = 38 × 100 / 95

x = 2 × 100 / 5

x = 2 × 20

x = 40

We have the following function that has been plotted in the figure below:

So we need to find three characteristics of this functions, namely, its period, range and amplitude, so let's find out:

1. Period

Consider this equation:

The period of this function is given by:

2. Range

The range of a function is the set of outputs. Therefore, as shown in the figure the range of this function is:

3. Amplitude

The amplitude represents half the distance between the maximum and minimum values of the function and is given by:
