What is the scale factor of ABC XYZ​

Mathematics

Svetlanka [38]3 years ago

Answer:  The correct option is (A) 6.

Step-by-step explanation:  We are given to find the scale factor of dilation from triangle ABC to triangle XYZ.

From the figure, we note that

The lengths of the sides of triangles ABC and XYZ are as follows :

AB = 5 units, BC = 4 units, AC = 3 units, XY = 30 units, YZ = 24 units and XZ = 18 units.

We know that

\textup{Scale factor}=\dfrac{\textup{length of a side of the dilated figure}}{\textup{length of the corresponding side of the original figure}}.

Therefore, for the given triangles, we get

\textup{Scale factor}=\dfrac{XY}{AB}=\dfrac{30}{5}=6.

Thus, the required scale factor of dilation is 6.

Option (A) is CORRECT.

Answer:

A

Step-by-step explanation:

To calculate the scale factor k, find the ratio of corresponding sides

\frac{XZ}{AC} = \frac{18}{3} = 6

\frac{YZ}{BC} = \frac{24}{4} = 6

Hence the scale factor k = 6 → A

5) Is 3 a zero (or root) of f(x) = x3 - 9x2 + 11x + 21?
frozen [14]

Answer:

Yes

Step-by-step explanation:

f(x) = x³ − 9x² + 11x + 21

f(3) = (3)³ − 9(3)² + 11(3) + 21

f(3) = 27 − 81 + 33 + 21

f(3) = 0

What fraction would represent the ratio of the cost
Stolb23 [73]
To write 3000 as a fraction you have to write 3000 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
3000 = 3000/1 = 30000/10

And finally we have:
3000 as a fraction equals 30000/10

What is the point-slope form of a line that has a slope of 5 and passes through the point (3, –4)?
Alinara [238K]

Answer:

y + 4 = 5(x - 3)

Step-by-step explanation:

In the Point-Slope Formula, <em>y</em><em> </em><em>-</em><em> </em><em>y</em><em>₁</em><em> </em><em>=</em><em> </em><em>m</em><em>(</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em>₁</em><em>)</em><em>,</em><em> </em>all the negative symbols give the OPPOSITE terms of what they really are.
