Answer:</h2><h2>
The frequency of the guitar string vibrates back and forth 88 times in 1 minute = 1.5 Hz</h2>
Step-by-step explanation:
A hertz is used to measure one cycle (complete wave) of a vibration.
The number of cycles per second is the frequency, measured in hertz.
A guitar string vibrates back and forth 88 times in 1 minute
The vibrations in 1 second = 
= 1.466 Hz ≈1.5 Hz
The frequency of the guitar string vibrates back and forth 88 times in 1 minute = 1.5 Hz
Sin V = opp/hyp
Sin 60 = opp/18
opp = sin 60 x 18
opp = 15.6
opp = 9 root 3

Answer: they do not have enough info but I will try my best to answer if im wrong its not my fault so please add more info
Solution
2. I know that for a Semi-Circle Area = 320 . From this find out Area of the Semi-Circle.
Solution:
Here Area=320(Given)
Area=
πr2
2
r2=
Area⋅2
π
r2=
320⋅2
22
7
r=14.2701
Diameter(d)=2r
=2⋅14.2701
=28.5402
Circumference=πr
=
22
7
⋅14.2701
=44.849
Perimeter=πr+2r
=
22
7
⋅14.2701+2⋅14.2701
=44.849+28.5402
=89.6979

I would say B, one because on A it is not NEARLY it IS, and second it is true, lol.
Answer:
Step-by-step explanation:
It is given that the regression equation
predicts an adult’s height (y) given the individual’s mother’s height (x1), his or her father’s height (x2), and whether the individual is male (x3 = 1) or female (x3 = 0).
The coefficient of x1 = 0.32 represents the increase in height of the child due to one inch increase in mother.
Similarly coefficient of x2 = 0.42 represents the increase in height of the child due to one inch increase in father.
and coefficient of x3 = 5.31 represents the increase in height of the child due to being a male than a female.
