A scientist has 50 grams of a radioactive element. The amount of radioactive element remaining after t days can be determined using the equation
f(0) - 50
(3)
After two days the scientist receives a second shipment of 50 grams of the
same element. The equation used to represent the amount of shipment 2 remaining after t days is R8) - 50
50l
. Which
of the following is an equivalent form of the expression for the amount remaining in shipment 2?

step-by-step explanation:

idk what the heck he answer is, i’m just putting this here so i finish my account

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.
