Answer:

a) How many loops does this pattern exhibit = 3Loops

b) What is the fundamental frequency of vibration of the wire = 50Hz

c) how many loops arepresent in the new pattern = 1 Loop

Step-by-step explanation:

The concept of general wave equation is applied and then compared to the equation given in the question to determine the amplitude A, and angular frequency w as shown in the attached file.

PART A
Coefficient
Coefficient h is 7.50
Coefficient s is 0.20

Variable
h and s

Constant
40

PART B
7.50h + 0.20s + 40
= 7.50(25) + 0.20(300) + 40
= 187.5 + 60 + 40
= 287.5
She earns $287.5

PART C
Yes, the coefficient of h would change to 9, the rests are still the same. Because she's no longer receive 7.50 per hour, and start earning 9 per hour, so the coefficient should change.
The expression would be
9h + 0.20s + 40

Find the area of the circle. Leave your answer in terms of pi.

Tom [10]

<h2>Answer:</h2>

$A=4.2025\pi$

<h2>Step-by-step explanation:</h2>

A circle is a curve made up of all the points having the same distance from the center. In terms of the diameter, that is any chord that passes through the center, the area can be found as:

$A=\pi (\frac{d}{2})^2$

We know that $d=4.1m$ then:

$A=\pi (\frac{4.1}{2})^2 \\ \\ A=\pi (2.05)^2 \\ \\ A=4.2025\pi$

So $4.2025\pi$ is the result and as you can realize this area is in terms of π
