Answer:
Period = pi
Angular frequency = 2
Amplitude = 5
Midline is the line y = 3
Step-by-step explanation:
A sinusoidal wave is written in the general form as:
f(x) = A*cos(w*x) + C
Where:
- A is the amplitude.
- w is the angular frequency, this is equal to 2*pi/T
where T is the period.
- y = C is the midline.
Then in the equation:
f(x) = 5*cos(2*x) + 3
- 5 is the amplitude.
- 2 is the angular frequency (in the image is called frequency, but this quantity must be in radians/time, while the normal frequency is only in Hz)
- We know that the angular frequency is equal to 2*pi/T, whit this eqation we can find the period:
2 = 2*pi/T
T = 2*pi/2 = pi
pi is the period.
- y = 3 is the midline.

Answer: 0.77
Step-by-step explanation:
17/22 = 0.7727
To the nearest hundredth in math means to round off to two decimal places, so here, 2 is less than 5, and so the final answer is
= 0.77
Answer:
-3
Step-by-step explanation:
- Plug in the value of x: 2(-3) + 3
- 2(-3) = 2 × -3 = -6
- Plug -6 in: -6 + 3
- -6 + 3 = -3
I hope this helps!
