Answer:
-17 degrees
Step-by-step explanation:
Given that:
Initial temperature = 2 degrees
Final temperature = -15 degrees
To Determine:
The change in temperature.
Solution:
First of all, let us have a look at the method for calculating the change in any quantity.
Let the initial quantity =
Let the final quantity =
Change in quantity = Final quantity - Initial quantity =
Here, we are given the quantity as temperature.
where degrees and
degrees
Therefore, the change in temperature = -15 - 2 = <em>degrees</em>
To solve this problem you must apply the proccedure shown below:
1. You must multiply the coordinates of by the scale factor given in the problem above. Therefore, you have that the coordinates of
are:
2. The midpoint of has the folllowing coordinates:
3. The center of dilation is a fixed point, with coordinates . Therefore, the distance from the center of dilation to the midpoint of
is:
The answer is the option C:
