The sounds of music are related to trigonometric functions because trigonometry is used in measuring the level of the pitch of a sound wave or musical note.
<h3>How is trigonometry used in sound?</h3>
It should be noted trigonometry is important for measuring pitch level. The notes are measured in Hertz.
A sound wave's amplitude relates to the change in the pressure that's caused by the wave measured at a specific location.
The sound is perceived as louder when the amplitude increases.
Pieces of music often have repetitive choruses or bars, similar to patterns. In mathematics, we look for patterns to interpret and predict the unknown. Music uses the same techniques. If you look at a piece of music, artists look at the notes they see to find the rare (high or low) and uncommon notes.
In this way, the notes are related. Relationships are important in mathematics and create an interesting link between music and mathematics.

Answer:
The rate of Yvone's hair growth is 3.1 cm per month.
Step-by-step explanation:
WIth the data from Yvonne's hair we can create a sequence that goes as follows:
A = {47, 50.1, 53.2, 56.3, 59.4,...}
This is an arithmetic sequence, the numbers are related to each other by a common difference, in other words to find the next number we just need to add a constant "r". To find this constant we can subtract any adjacent numbers on this sequence, this is shown below:
r = 50.1 - 47 = 3.1
r = 53.2 - 50.1 = 3.1
r = 56.3 - 53.2 = 3.1
and so on.
The rate of Yvone's hair growth is 3.1 cm per month.
Most of these are wrong....?
4+1=5
2+5 is not 12, it is 7
3+6 is not 21, it is 9
8+11= 19
