Question

Given a dilation with the origin O (0, 0), by observation determine the scale factor "K." DO, K = (5, 0) (10, 0) What is the scale factor K? Answers 1/2, 2, 5

Answer 1

Answer:

k = 2

Step-by-step explanation:

Given :  a dilation with the origin O (0, 0), by observation determine the scale factor "K."

Given the point  (5, 0) is dilated to point (10, 0) .

We have to determine the scale factor K.

DILATION is the process by which we can increase or decrease the size of an figure by a scaling factor.

If scaling factor is greater than 1 then the figure increase its size and if scaling factor is less than 1 then the figure decrease its size.

Since dilation with the origin O (0, 0) of point  (5, 0) is dilated to point (10, 0) .

Thus, the size of line segment is increases and thus the scaling factor is given by  $\text{scale factor}=\frac{\text{new figure}}{\text{original figure}}$

Thus, for given

$\text{scale factor}=\frac{10}{5}=2$

Thus, k = 2
