7. Given the function sin(-x – ) a) Sketch the terminal arm in the correct quadrant.
b) Simplify sin(-x -).

a is the right answer

it is 10.6 according to my calculations

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.

sorry for any inconvenience this may have caused try again

try again.
