(I)
firstly , we will find maximum and minimum y-value
we can see that
maximum value is 5
minimum value is -5
so, we can find amplitude
..........Answer
(II)
we know that
wave length is the length of one wave
we can see that from B to F , there is one wave
and we are given it's length as 20cm
so, wavelength is 20cm......Answer
(III)
we know that
we are given
frequency =100hz
wavelength =20cm
now, we can find velocity
............Answer
Answer:
(3x +4)(9x^2-12x+16)
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
The question asks for f(3). f(3) is the y value. "3" is the x value. In other words the question asks, "What is the value of y when x is 3?"
When x is 3, y=7.
Answer: The answer is 10. X = 10.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given the system of equations:
You can pply Substitution method:
First you must solve for "y" from the first equation:
Therefore, the second and final step to solve the system of equations is to substitute the value of "y" into the second equation and solve for "x":
