Triangle STV has vertices S (-3, -2) , T (-4, 3) and V (-2, 3). If (x, y) arrow (x+2, y-3), what are the vertices of its image?

jeka94

Answer:

see below

Step-by-step explanation:

The mapping tells you how to find the vertices of the image:

(x, y) ⇒ (x +2, y -3)

S(-3,-2) ⇒ S'(-3 +2, -2 -3) = S'(-1, -5) . . . . . matches choice D

T(-4, 3) ⇒ T'(-4 +2, 3 -3) = T'(-2, 0)

V(-2, 3) ⇒ V'(-2 +2, 3 -3) = V'(0, 0)

Find the volume of a cylinder whose base is an ellipse with axes of 12 inches and 7 inches. The altitude of the cylinder is 21 i

Tpy6a [65]

if the ellipse has a major axis of 12 inches, that means its major radius is half that, or 6, and if its minor axis is 7, then its minor radius is half that, 3.5.

$\bf \textit{volume of an elliptical cylinder}\\\\
V=\pi ab h~~
\begin{cases}
a=\textit{major axis radius}\\
b=\textit{minor axis radius}\\
h=height\\[-0.5em]
\hrulefill\\
a=6\\
b=3.5\\
h=21
\end{cases}
\\\\\\
V=\pi (6)(3.5)(21)\implies V\approx 1385.44236023309881816203$
