We know that
Inverse Variation is a<span> relationship between two variables in which the product is a constant
so
let
x------> a pitch of a musical instrument
y------> </span><span>the wavelength
x*y=k
find the value of k
for x=</span><span>220 hertz y=3 ft
</span><span>x*y=k
220*3=k
k=660
</span>for x=165 hertz y=4 ft
x*y=k
165*4=660
k=660<span>
the answer part a) is
</span><span>the type of variation between pitch and wavelength is an inverse variation
</span>
part b) <span>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</span>
Answer:
Step-by-step explanation:
Answer:
F(x) and h(x)
Step-by-step explanation:
f(x) has a high of three and so does H(x), g(x) has a high of -2 so it doesn't count
Answer:
59.0 miles per hour
Step-by-step explanation:
When you have an equation with an absolute value, you must consider two options: one with a positive result and another one with a negative result.
In this case you need the maximum safe driving speed which is 59.2 miles per hour
Imaginary numbers ? just equate the imaginary with imaginary and real with real
