Answer: 2(5c - 1x)
Step-by-step explanation: It's asking you to take out the greatest common factor (GCF).
The expression is Undefined for x=0, assuming you intend 1/(-8x).
x=0 is "nonpermissible"
Simplified answer is 4+8i
280,706 is the standard form
Answer:
The frequency of the note a perfect fifth below C4 is;
B- 174.42 Hz
Step-by-step explanation:
Here we note that to get the "perfect fifth" of a musical note we have to play a not that is either 1.5 above or 1.5 below the note to which we reference. Therefore to get the frequency of the note a perfect fifth below C4 which is about 261.63 Hz, we have
1.5 × Frequency of note Y = Frequency of C4
1.5 × Y = 261.63
Therefore, Y = 261.63/1.5 = 174.42 Hz.
