Answer:
A dilation (similarity transformation) is a transformation that changes the size of a figure. It requires a center point and a scale factor , k . The value of k determines whether the dilation is an enlargement or a reduction.
In simple words, it's stretching, when you dilate with scale factor of x, means you multiply the previous value with x, say co-ordinates area -2,4, so you do (-2x,4x) to find the co-ordinates after dialation,
Here the scale factor is 3, so the new co-ordinates are,
(-2×3, 4×3) which is A' (-6, 12)
similarly,
B' (12, -3)
C' (-3, -6)

Answer:
The equations of both cups after t minutes is given by:
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
