No, Yes, No, Yes
using the laws of exponents
(1)
(
)³ = 
4³ × 4³ = 
≠ → No
(2)
(
)^4 = 
× = → Yes
(3)
= (6 × 3 )^8 = 
× ≠ 
× → No
(4)
= (4 × 5 )³ = 4³ × 5³ → Yes
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>
I hope you find the answer I need point sorry
Answer:
(72-40) = 8 x (9-5)
Step-by-step explanation:
GCF = 8
(72-40) = 8 x (9-5)
The answer is 5 . because if you count the # it will go to 28
