Mark is using two functions to determine how much money he will have in his account after t years. He uses the constant function f(t)= 2500 and an exponential function g(t)=1.05' to create the function h(t)= f(t):g(t) which represents the value, in dollars, of his account earning interest. Based on the function h(t), what will be the value of the account after 8 years? Round to the nearest dollar.

1. $2625
2. $3694
3. $20,000
4. $21,000

answer: y=0 if that is what u r looking for

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

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.
