The length of the rope was yard
Jeff cut the rope into 3 pieces.
Each piece is a different length measured in eighths of a yard which means that the denominator of each piece should be same which is 8
As each piece is of different length so the numerator of each piece will be different.
But the total of the numerator should be 6
So the numerators will be 1, 2 and 3
Since 1 + 2 + 3 = 6
So length of each piece will be
yard
yard
and yard
Answer:
10 hours or 2 hours
Step-by-step explanation:
Condition 1 - Both the trains are moving the a same direction.
- Time = distance÷(speed of A - speed of B)
- Time = 500÷(150-100) = 10 hrs
- It will take 10 hrs for them to meet and they will meet exactly at 150×10 = 1500 km from Point A
Condition 2 - Both the trains are moving in opposite directions.
- Time = distance÷ (speed of A + speed of B)
- Time = 500÷(150+100) = 2 hrs
- It will take 2 hrs for them to meet and they will meet exactly at 150×2 = 300 km from Point B
I know this because I don’t see a diagram
1. The four subintervals are [0, 2], [2, 5], [5, 6], and [6, 7]. Their respective right endpoints are 2, 5, 6, and 7. If denotes the change in sea level years after 2010, then the total sea level rise over the course of 2010 to 2017 is
approximated by the Riemann sum,
2. The sum represents the definite integral
That is, we partition the interval [1, 4] into subintervals, each of width . Then we sample points in each subinterval, where is the point used in the th subinterval, then take its square root.
3. The integral is trivial:
4. Using the fundamental properties of the definite integral, we have
5. First note that is undefined at , so the integral is improper. Recall that . Then
Now,
where is any integer.
