Answer:
The Riemann Sum for with n = 4 using midpoints is about 24.328125.
Step-by-step explanation:
We want to find the Riemann Sum for with n = 4 using midpoints.
The Midpoint Sum uses the midpoints of a sub-interval:
where
We know that a = 4, b = 5, n = 4.
Therefore,
Divide the interval [4, 5] into n = 4 sub-intervals of length
Now, we just evaluate the function at the midpoints:
Finally, use the Midpoint Sum formula
This is the sketch of the function and the approximating rectangles.
