Answer:

C y = 4x - 12

Step-by-step explanation:

(1,-8) means x=1, y=-8

(4,4) means x=4, y=4

so, for which of the offered equations are both pairs right ?

a -8 = 4x1 + 12 = 16 wrong already for the first pair

b -8 = -4x1 - 12 = -16 wrong already for the first pair

c -8 = 4x1 - 12 = -8 hey, right !

4 = 4x4 - 12 = 16 - 12 = 4. hey, right

d -8 = -4x4 + 12 = -16 + 12 = -4. wrong already for the first pair

so, C describes an equation that covers both points. it is a linear function (no squares or so), and so it is a line function passing through both points.

<h2>Answer:</h2>

D. Distance formula

<h2>Step-by-step explanation:</h2>

The \ \mathbf{distance} \ d \ between \ the \ \mathbf{points} \ (x_{1},y_{1}) \ and \ (x_{2},y_{2}) \ in \ the \ plane \ is:\\ \\ d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

As in the statement:

<em>The distance form</em> (0,0) to (0,2) is \sqrt{(0-0)^2+(2-0)^2}=\sqrt{2^2}=2 <em>whose justification is the </em><em>Distance Formula. </em>

<em />

Here in this statement the justification is also the Distance Fromula, so we take the distance from (0,0) \ to \ (1,\sqrt{2}) whose result is also 2 and is the radius of the circle.

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)
