Katie runs 1 mile every 6 mins so she can run 5 miles in 30 mins.
X^2 + Y^2 = 4 This centers at origin, since h and k values are zero ( therefore nonexistent) and the radius is 2 so it goes through (-2,0)
Not sure but I think its C.
The answer is -20 I hope this helped
Answer:
The problem with this question is that it is missing an important number, which is the length of the tube. Assuming that the tube is 10 meters long (=1,000 centimeters long)
time (in distance traveled distance traveled distance
seconds) by particle A in cms by particle B in cms between both
particles in cms
1 97 49 854
2 93 47 714
3 89 45 580
4 85 43 452
5 81 41 330
6 77 39 214
7 73 37 104
8 69 35 0
After 8 seconds both particles should meet. Particle A traveled 664 centimeters and particle B traveled 336 centimeters.
