Be sure to answer all parts. list the evaluation points corresponding to the midpoint of each subinterval to three decimal places, sketch the function and approximating rectangles and evaluate the riemann sum to six decimal places if needed. f(x) = x2 + 4,[4, 5], n = 4. give your answer in an ascending order. evaluation points: , ,

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.

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
