The base of a solid right pyramid is a square with an

zhuklara [117]

Answer:

Volume = ⅓n²(n-1) or ⅓(n³ - n²)

Step-by-step explanation:

Given

Solid Shape: Right pyramid

Edge= n units

Height= n - 1 units

Required

Volume of the pyramid

The volume of a right pyramid is

Volume = ⅓Ah

Where A represents the area of the base

h represent the height of the pyramid

Since it has a square base;

The area is calculated as follows

Area, A = edge * edge

A = n * n

A = n²

Recall that

Volume = ⅓Ah

Substitute n² for A and n - 1 for h

The expression becomes

Volume = ⅓ * n² * (n - 1)

Volume = ⅓n²(n-1)

The expression can be solved further by opening the bracket

Volume = ⅓(n³ - n²)

Geometry Question Please Help!!!!

lora16 [44]

The equation of a parabola is given by $f(x)=a(x-h)^{2}+k$ where $(h,k)$ is the vertex.

We have the vertex is (-3,-2) so we have $h=-3$ and $k=-2$

Substituting -3 and -2 into the $f(x)$
$f(x)=a(x--3)^{2}+(-2)$
$f(x)=a(x+3)^{2}-2$

Hence, the correct answer is option D
