Answer:
B. 4
Step-by-step explanation:
The given function is of the form:
![f(x) = A \cos(x+C).](https://tex.z-dn.net/?f=f%28x%29%20%3D%20A%20%5Ccos%28x%2BC%29.)
A is called the amplitude of the given function.
We can read from the graph that, the function ranges between:
-4 and 4
This implies that:
![|A| = 4](https://tex.z-dn.net/?f=%7CA%7C%20%3D%204)
Therefore the amplitude of the function is 4.
Hence the value of A must be 4.
The correct answer is 6*10^-6 ..........................
Answer:
○ ![\displaystyle 25](https://tex.z-dn.net/?f=%5Cdisplaystyle%2025)
Step-by-step explanation:
![\displaystyle 4 = 2\sqrt{25} - 6 \\ 4 = 2[5] - 6 \\ \\ 4 = 10 - 6](https://tex.z-dn.net/?f=%5Cdisplaystyle%204%20%3D%202%5Csqrt%7B25%7D%20-%206%20%5C%5C%204%20%3D%202%5B5%5D%20-%206%20%5C%5C%20%5C%5C%204%20%3D%2010%20-%206)

Answer:
its a discrete graph
Step-by-step explanation:
hope this helps
Try this solution:
for the circle A: circumference=6π, area=9π
for the circle B: circumference=12π, area=36π
PS. formula for circumference is 'L=2πr', for area is 'S=πr²'.
