Answer:
Option (1)
Step-by-step explanation:
Equation of the given wave function,
f(x) = acos(bx)
Here, a = amplitude of the wave
Period of the wave = ![\frac{2\pi }{B}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%20%7D%7BB%7D)
From the graph attached,
Amplitude = ![\frac{4-(-4)}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B4-%28-4%29%7D%7B2%7D)
= ![\frac{4+4}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B4%2B4%7D%7B2%7D)
= 4
Period of the wave = π - 0
= π
From the formula of the period,
Period = ![\frac{2\pi }{b}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%20%7D%7Bb%7D)
![\pi =\frac{2\pi }{b}](https://tex.z-dn.net/?f=%5Cpi%20%3D%5Cfrac%7B2%5Cpi%20%7D%7Bb%7D)
b = 2
Therefore, a = 4 and b = 2.
Option (1) will be the answer.

Answer: They need 20 more meters of tape.
This is because they are putting tape around the perimeter. To find the perimeter you add up each side.
This is shown like this
20+20+40+40=120meters.
But the question is asking how many more meters of tape does the company so we subtract the amount of tape they already which is 100meters from 120meters.
So it can be written like this
120m -100m = 20meters of tape
Answer: the company needs 20 more meters of tape.

Step-by-step explanation:
Answer: If ∡PQR = 82°, and the ray QS bisects it, it cuts ∡PQR into two equal halves, ∡PQS and ∡RQS, each of which is then 82/2, or 41°.
