If you look at the graph of sin(n), you can notice that it oscillates every kpi/2 when k is odd. This oscillation proves that sin(n) diverges.
Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
Answer:
the answer is D. I just took the exam.
Step-by-step explanation:
P= 4(348) because assuming the wear house has four sides that is the only logical answer
convert the feet to inches
1 foot = 12 inches
so 1.5 ft =1.5*12 = 18 inches
now multiply all 3
14*18*7 = 1764 cubic inches
