Answer:

\frac{n^{2}  (n - 1)}{3} \\

Step-by-step explanation:

1) Using the formula for finding the volume of a pyramid:

A = (1/3)lwh

2) Since the base is a square, the length and width will be the same:

A = (1/3) x n x n x (n-1)

A = \frac{n^{2}  (n - 1)}{3} \\

For this case we have that by definition, the volume of a pyramid is given by:

V = \frac {A_ {b} * h} {3}

Where:

A_ {b}:It is the area of the base

h: It is the height

According to the data we have that the base of the pyramid is square, so its area is:

A_ {b} = n * n = n ^ 2\\h = n-1

Substituting we have:

V = \frac {n ^ 2 * (n-1)} {3}

Answer:

V = \frac {n ^ 2 * (n-1)} {3}

1.(03.03 MC) The table below represents a linear function f(x) and the equation represents a function g(x).
Mama L [17]
The slope of f(x) is 10 and the slope of g(x) is 5; g(x) has the greater y-intercept.

To find the slope of f(x), we use the slope formula:  m=(y₂-y₁)/(x₂-x₁) = (-1--11)/(0--1) = (-1+11)/(0+1) = 10/1 = 10.

To find the slope of g(x), we just look at the form it is in.  It is written in slope-intercept form, y=mx+b, where m is the slope.  The number in g(x) that would correspond to m is 5.

The y-intercept of f(x) is found by looking at the points.  Any y-intercept will have an x-coordinate of 0; the only point like this in the table is (0, -1) so the y-intercept is -1.

For g(x), we again look at the form y=mx+b.  The number that corresponds with b is the y-intercept; in this case, it is 1.  1>-1, so g(x) has the larger y-intercept.

A regular polygon inscribed in a circle can be used to derive the formula for the area of a circle. The polygon area can be expr
Marat540 [252]

Answer:

Option (D)

Step-by-step explanation:

Formula to get the area of a regular polygon in a circle will be,

Area = n[\frac{1}{2}\times (\text{Base})\times (\text{Height})]

        = n[\frac{1}{2}\times (\text{s})\times (\text{h})]

Here 'n' is the number of sides.

If n increases, h approaches r so that 'rh' approaches r².

In other words, if the number of sides of the polygon gets increased, area of the polygon approaches the area of the circle.

Therefore, Option (4) will be the answer.
