The correct answer would be to divide both side by 64 so (A)
Answer: 8 meters per second
Step-by-step explanation:
Hi, to answer this, first, we have to divide the time counted by the number of waves, to obtain the time of each wave:
10 /20 = 0.5 seconds per wave
Now, we simply divide the distance given by the time, to obtain the speed rate:
4/0.5 = 8 meters per second

Answer:
(0,0) and (-530,0)
Step-by-step explanation:
If you have to use the quadratic formula, you need to know your A, B, and C values. Your A value is 4, your B is 2120, and your C value, or constant, appears to be zero. Then you need to plug these values into the quadratic formula to get 0 and -530. This would make your roots to be at points (0,0) and (-530,0).

Answer:
x=-1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)=(6-3)/(-1-(-1)=3/(-1+1)=3/0
your slope is undefined.
