We know that
Inverse Variation is a relationship between two variables in which the product is a constant
so
let
x------> a pitch of a musical instrument
y------> the wavelength
x*y=k
find the value of k
for x=220 hertz y=3 ft
x*y=k
220*3=k
k=660
for x=165 hertz y=4 ft
x*y=k
165*4=660
k=660
the answer part a) is
the type of variation between pitch and wavelength is an inverse variation
part b) What is the pitch when the wavelength is 5 feet?
x=?
y=5 ft
k=660
x*y=k------> solve for x
x=k/y----------> x=660/5-----> x=132 hertz
the answer Part b) is
132 hertz
Answer:
<h3>x = 22.62°</h3>
Step-by-step explanation:
To find the measure of angle x we use cosine
From the question
PO is the hypotenuse = 13
The adjacent is 12
Substitute the values into the above formula
That's
x = 22.6198
We have the final answer as
<h3>x = 22.62° to the nearest hundredth</h3>

Answer:
1a) 1:2
1b) 2:3
Step-by-step explanation:
1a) 4:8 = 1:2
1b) 4 white and 8 red means 12 total so ratio for red would be 2:3
