Answer: D
Frequency = 587.32 Hz
Step-by-step explanation:
One octave above has a frequency of 2 × 146.83 Hz = 293.66Hz (D4). Two octaves above has afrequency of 2 × 293.66 Hz = 587.32 Hz (D5)
Answer:
3x
Step-by-step explanation:
givens: x=4
now try your options:
3(4)+3=15
12+3=15
15=15
The first option is correct, therefore the answer is 3x
Answer:
Step-by-step explanation:
Identities : -
cot = cos / sin
tan = sin / cos
( cot + tan ) sin = sec
LHS
= ( cot + tan ) sin
= ( ( cos / sin ) + ( sin / cos ) ) sin
= ( ( cos sin ) / sin ) + ( sin² / cos )
= cos + ( sin² / cos )
LCM = cos
= ( cos² / cos ) + ( sin² / cos )
= ( cos² + sin² ) / cos
Identity : -
cos² + sin² = 1
= 1 / cos
= sec
= RHS
Hence proved.
