Answer:
Step-by-step explanation:
Given: Jabari's total fee, f, for a single job is a function of the number, t, of hours it takes him to complete the job.
For every job, he charges an initial fee plus $30 for each hour of work.
let m be his initial fee.
Then .......(1)
Also, his total fee for a 4-hour job, for instance, is $170.
Put t=4 and f=170 in (1), we get
Now, put m=50 in the (1), we get the function's formula for Jabari's total fee, f as
Trigonometry functions is often employed in taking the measurement of the level or the pitch of a sound wave or musical note.
The change of amplitude of a sound wave's amplitude is linked to the change in pressure that occurs due to the wave measured at a given location.
Frequency tells the number of waves that pass a fixed location in a specific time frame.
<h3>How does sound waves relate to trigonometric functions?</h3>Sound engineers uses the basic laws of trigonometry via sine and cosine graphs.
Note that all sounds can be broken down into a lot of sine waves, as sine waves comes together to form sounds.
Therefore, Trigonometry functions is often employed in taking the measurement of the level or the pitch of a sound wave or musical note.

Answer:
The saucer's circumference is <u>25.12 centimeter</u>.
Step-by-step explanation:
Given:
Linda calculated that the saucer for her tea cup has an area of 50.24 square centimeters.
Use 3.14 for π.
Now, to find the saucer's circumference.
So, we get the radius first by putting the formula of area:
Area = 50.24 square centimeters.
Let radius be
As given we use 3.14 for π.
<em>Dividing both sides by 3.14 we get:</em>
<em>Using square root on both sides we get:</em>
Thus, the radius = 4 centimeters.
Now, to get the circumference we put formula:
Circumference = 25.12 centimeter.
Therefore, the saucer's circumference is 25.12 centimeter.
