Answer:
698.46 Hz
Step-by-step explanation:
A note an octave higher than another note is double the amount of frequency.
In this example, the note is 349.23 Hz. Doubled, this is 698.46 Hz. Therefore, the final answer is the first option, 698.46 Hz
It would be the second one because since it’s at 5. You shift from 5 to 8 three units to the right
Answer:
Step-by-step explanation:
A + B = 90
A/6(15.25) = 3B/4
61A/18 = B
18A/18 + 61A/18 = 90
A = 90(18)/79
A = 20 40/79°
B = 90 -A = 69 39/79°
You can tell if two lines are parallel, perpendicular, or neither by looking at their slopes and :
- If , i.e. if the two lines have the same slope, the lines are parallel
- If , the lines are perpendicular
- In all other cases, the lines are not parallel nor perpendicular.
Given two points of a line, the slope is defined as the ratio between the y and x variation:
So in this case, we have
Since the two slopes are the same, the two lines are parallel.
