The given table shows the cost f(t), in dollars, of item B after t years. Reminder: The function for item A was c(x) = 72(1.25)x. Which item recorded a greater percentage change in cost over the previous year?

A.
Product A; it changed by 125%

B.
Product A; it changed by 25%

C.
Product B; it changed by 130%

D.
Product B; it changed by 30%

answer: c. im 100 percent sure

step-by-step explanation:

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.

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
