3. Consider this dilation.
(a) Is the image of the dilation a reduction or an enlargement of the original figure? Explain.
(b) What is the scale factor? Explain.

 The answers are:

(a) The dilation is a reduction of the original figure.

(b) The scale factor of dilation is 2/3

Step-by-step explanation:  We are given a dilation from ΔMSV to ΔM'S'V'.

We are to check whether the dilation is a reduction or an enlargement of the original figure. Also, to find the scale factor of dilation.

We know that if a figure is dilated to form the image figure, then the scale factor of dilation is given by

If S < 1, then the dilation will be a reduction and if S > 1, then the dilation will be an enlargement.

We can note from the figure that

the co-ordinates of the vertices of the original triangle MSV are M(-3, 3), S(6, 3) and V(3, -3),

and the co-ordinates of the dilated triangle M'S'V' are M'(-2, 2), S'(4, 2) and V'(2, -2).

So, the lengths of the corresponding sides MS and M'S' of both the original and dilated figures are calculated using distance  formula as follows:

Therefore, the scale factor of dilation is given by

Step-by-step explanation:

b

Step-by-step explanation:

the scale factor is b

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
