Answer:
4th
Step-by-step explanation:
string length is 0.5m and the wavelengths are 0.25meters. This tells us there are two complete waves in the guitar string. This gives us a total of four antinodes; thus we are in the fourth harmonic.
So first lets do the fraction: 68/80. This is probably the most simple part, but if you want to simplify it you could go all the way down to 17/20.
For decimalthen you divide 68 by 80, and that is .85! Then to get your percentage, you multiply it by 100 and end up with 85%.
Percent: 85%
Fraction: 68/80 or 17/20
Decimal: 0.85
Hope this helps!
Okay. Let's start with eliminating answers. Because they're colored in dots, we know that this is a line segment. That means the domain is restricted. So not D.
A, B, C, are in correct because they're just like it's anything larger -1. This is true, but because this is a segment, then we know that it ends at some point.
So it's E.
Final answer: solve for the the dividend and the divisor. Then divide and you should have the answer of 560
