The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
(1)
Where:
- Final temperature, in degrees Celsius.
- Initial temperature, in degrees Celsius.
- Time, in minutes.
- Cooling rate, in
.
- Current temperature, in degrees Celsius.
Please notice that substance reaches thermal equilibrium when
, that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that
,
,
and
, then the cooling rate of the substance is:





The cooling rate of the substance is approximately 0.0732.

If triangle ABC undergoes a dilation of scale factor 3 centered at the origin, the coordinate of the image of point B is known to be option D. (6,9).
<h3>What is the dilation about?</h3>
The term Dilation is known to be a kind of a transformation, that is used to change the size of an object.
Note that Point B has coordinates of (2, 3)
So the Dilation factor 3 will alter the coordinates as:
(2*3, 3*3)
= (6, 9)
Hence, If triangle ABC undergoes a dilation of scale factor 3 centered at the origin, the coordinate of the image of point B is known to be option D. (6,9).
