{(-12,-5),(-10,5), (10,-5), (12,5)}
A. Domain: -12 Range: -5 sys5
B. Domain: {-5,5)
Range:{-12, -10, 10, 12}
C. Domain: {10, 12}
Range: {5}
D. Domain: {-12, -10, 10, 12)
Range: {-5,5)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
