For the dilation, DO, K = (10, 0) → (5, 0), the scale factor is equal to _____. -5 5 0.5 2

ozzi

Answer:

The scale factor of the following dilation is, 0.5

Step-by-step explanation:

The rule of dilation with scale factor k is given by:

$(x, y) \rightarrow (kx, ky)$

As per the statement:

Given the following dilation:

(10, 0) → (5, 0) .....[1]

We have to find the scale factor.

Using the above rule we have;

$(10, 0) \rightarrow (10k, 0k)$

Now compare this with equation [1] we have;

(10k, 0) = (5, 0)

⇒10k = 5

After solving we get;

$k = \frac{1}{2}=0.5$

Therefore, the scale factor of the following dilation is, 0.5
