C.
You can factor that equation to the following:
x(x - 3)(x + 2)
Then set each part equal to zero and solve individually.
Answer:
5.5 cm
Step-by-step explanation:
A perfect fifth above a note has a frequency ratio of 3 to 2.
Therefore, we can set the proportion:
164.81 : x = 2 : 3
which gives:
x = <span>164.81 </span>× 3 ÷ 2
= 247.21
Hence, the perfect fifth above E₃ will have a frequency of 247.21Hz which corresponds to a B₃.
For this case we must resolve the following inequality:
Applying distributive property on the left side of inequality we have:
Subtracting 5 from both sides of the inequality:
Subtracting 4x from both sides of the inequality:
Thus, the result is
