A triangle with vertices at A(0, 0), B(0, 4), and C(6, 0) is dilated to yield a triangle with vertices at A′(0, 0), B′(0, 10), a
sineoko [7]
ANSWER

The scale factor is
2.5

EXPLANATION

The given triangle has vertices,

A(0,0),B(0,4),\:and\:C(6, 0).

The vertices of the image triangle is,

A'(0,0),B'(0,10),\:and\:C'(15, 0).

The scale factor is given by

k = \frac{image \: length}{object \: length}

So we can use any of the corresponding sides to determine the scale factor,

k = \frac{|A'B'|}{ |AB|}

k = \frac{ |10 - 0| }{ |4 - 0|}

k = \frac{ |10| }{ |4 |} = \frac{10}{4} = 2.5

Or

k = \frac{|A'C'|}{ |AC|}

k = \frac{ |15 - 0| }{ |6 - 0|}

k = \frac{ |15| }{ |6|} = \frac{15}{6} = 2.5


Or

k=\frac{|B'C'|}{|BC|}

k = \frac{\sqrt{(15 - 0)^2+(0-10)^2 }}{\sqrt{(6 - 0)^2+(0-4)^2}}

k = \frac{ 5\sqrt{13}}{2\sqrt{13}} = \frac{5}{2} = 2.5

The correct answer is C

Vsevolod [243]

Answer:

The result is

\frac{5}{2}

Or

2.5

Step-by-step explanation:

We want to simplify

\frac{5}{8}  \times 4

We know that 4 goes into 8 twice.

This implies that:

\frac{5}{8}  \times 4 =  \frac{5}{2}

We can convert the result into decimals as follows:

\frac{5}{2}  =  \frac{25}{10}  = 2.5
