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.

If the image is the one shown, then these are the answers:

The image is a reduction, the M’, S’, V’ triangle is smaller than the original, M, S, V triangle.  

The scale factor is 2/3, as the points are M (-3,3),  M’(-2,2),  S (6,3),  S’(4,2),  V (2,-2), and V’(3,-3).

Step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
