The formula of a volume of a pyramid:

V=\dfrac{1}{3}A_BH

A_B - area of a base

H - height of a pyramid

Calculate the area of the base:

A_B=10^2=100\ u^2

Calculate the length of height of the pyramid using the Pythagorean theorem:

H^2+5^2=13^2\\\\H^2=25=169\ \ \ |-25\\\\H^2=144\to H=\sqrt{144}\to H=12

Calculate the volume of the pyramid:

V=\dfrac{1}{3}\cdot100\cdot12=100\cdot4=400\ u^3

Find the Riemann sum for
Rom4ik [11]

Mathematically speaking, the Riemann sum of the <em>linear</em> function is represented by A ≈ [[4 - (- 6)] / 5] · ∑ 2 [- 6 + i · [[4 - (- 6)] / 2]] - [[4 - (- 6)] / 5] · ∑ 1, for i ∈ {1, 2, 3, 4, 5}, whose representation is represent by the graph in the lower left corner of the picture.

<h3>What figure represents a Riemann sum with right endpoints?</h3>

Graphically speaking, Riemann sums with <em>right</em> endpoints represent a sum of <em>rectangular</em> areas with equal width with <em>excess</em> area for <em>positive</em> y-values and <em>truncated</em> area for <em>negative</em> y-values generated with respect to the x-axis. Mathematically speaking, this case of Riemann sums is described by the following expression:

A ≈ [(b - a) / n] · ∑ f[a + i · [(b - a) / n]], for i ∈ {1, 2, ..., n}

Where:

a - Lower limit

b - Upper limit

n - Number of rectangles

i - Index of a rectangle

If we know that f(x) = 2 · x - 1, a = - 6, b = 4 and n = 5, then the Riemann sum with right endpoints of the area below the curve is:

A ≈ [[4 - (- 6)] / 5] · ∑ 2 [- 6 + i · [[4 - (- 6)] / 2]] - [[4 - (- 6)] / 5] · ∑ 1, for i ∈ {1, 2, 3, 4, 5}
