Tan(ANGLE) = Opposite Leg / Adjacent Leg
Tan(60) = Y/8
Y = 8 x tan(60)
Y = 8√3
Y = 13.9
Answer:
r = 2
Step-by-step explanation:
2(8r + 5) = 24 + 9r
16r + 10 = 24 + 9r
16r - 9r = 24 - 10
7r = 14
r = 2
A correlation coefficient of 1 or -1 indicates that the variables form a perfect linear relationship.
The speed at which they are moving apart = 475 + 525 = 1000 mi/h
Time = distance / speed
= 6000 / 1000 = 6 hours
The answer is 6 hours.
