Answer:

492.87cm^3

Step-by-step explanation:

Given data

Diameter= 4.9cm

The expression for the volume is

V= 4/3 πr^3

Substitute

V= 4/3*3.142*4.9^3

V= 4/3*3.142*117.649

V=1478.612632 /3

V=492.87 cm^3

Hence the volume is 492.87cm^3

On a coordinate plane, quadrilateral Q R S T has points (0, 2), (negative 4, 0), (0, negative 3), and (4, 0).
Afina-wow [57]

By applying the definitions of <em>rigid</em> transformation ((x, y) → (0.5 · x, 0.5 · y)) and dilation, we conclude that the coordinates of Q'(x, y) are (0.1).

<h3>How to apply rigid transformations on a point</h3>

Herein we must apply a rigid transformation into a given point to determine an image. <em>Rigid</em> transformations are transformations applied on a <em>geometric</em> locus such that <em>Euclidean</em> distance is conserved. Dilations are a kind of <em>rigid</em> transformations such that:

(x, y) → (k · x, k · y), for k > 0

If we know that Q(x, y) = (0, 2) and k = 0.5, then the coordinates of Q' are:

Q'(x, y) = (0.5 · 0, 0.5 · 2)

Q'(x, y) = (0, 1)

By applying the definitions of <em>rigid</em> transformation ((x, y) → (0.5 · x, 0.5 · y)) and dilation, we conclude that the coordinates of Q'(x, y) are (0.1).

Write the equation of the line that passes through the points (-6,8)(−6,8) and (8,8)(8,8). Put your answer in fully reduced poin
Artemon [7]

Answer:

y=8

Step-by-step explanation:

Point slope is y2-y1 over x2-x1

So its 8-(-6)  over 8-8 which equals 14/0 which means the equation of the line is y=8

This is a horizontal line on 8 on the y axis
