Suppose the interval [negative 3−3,negative 1−1] is partitioned into nequals=44 subintervals. What is the subinterval length Upper Delta xΔx? List the grid points x0, x1, x2, x3, x4. Which points are used for the left, right, and midpoint Riemann sums?

Δx = 0.5

Step-by-step explanation:

We have the interval:

[−3, −1]

and we partition it into 4 equal intervals.

first, the range of our interval is equal to the difference between the extremes, this is:

-1 - (-3) = -1 + 3 = 2

Then, if we divide it into 4, we have 4 segments with a range of:

2/4 = 0.5

Then the subinterval delta is 0.5, and the 4 intervals are:

[−3, -2.5],  [−2.5, −2],  [−2, −1.5],  [−1.5, −1]

B, 5

Step-by-step explanation:

Alright. I'll try my best to explain how I got the awnser.

Ussualy, you square root a number, not cube root it. When you square root a number, you find the square of the number.

Ex: sqrt 25=5 The square root of 25 is 5, meaning that if you mutiplied 5 by 5, it would be 25.

Cube root is different. You want to find the cube of a number. Its the same as a square root, except you want to mutiply a number by itself 3 times, not two.

Ex: sqrt 8=2 2 times 2 times 2 is 8.

Problem:

sqrt 125=5 since 5 times 5 times 5 is 125.

Hope this helps!
