Given:
The point is B(2,5) and its image is B'(1,2.5).
To find:
The scale factor.
Solution:
If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as
x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is
Therefore, the scale factor is and the correct option is D.

Step-by-step explanation:
The complete exercise says:
Two cups of coffee are poured from the same pot. The initial temperature of the coffee is 180°F, and is 0.2337 (for time in minutes).
Newton's law of cooling:
where,
= room temperature
= initial temperature
k=cooling constant
Hence,
<u>Cup 1:</u>
= 75 °F
= 180 °F
<u>Cup 2:</u>
= 75 °F
= 162 °F
