The value of the dirt bike, in dollars, can be calculated using the expression shown below, where t is time, in years. 8,690(0.95)^12t Use the given expression to complete the statements below. The quantity that represents the initial value of the dirt bike is _____. The quantity that reveals the rate at which the value of the dirt bike is decreasing is _____, which means the decay rate of the dirt bike is _____ %. The quantity that represents the number of times the value of the dirt bike decreases each year is _____.

minustempo:

the principal is the initial value here. which is 8690

minustempo:

0.95 means every certain amount of time (determined by the exponent), the bikes value is 0.95 times the value before that time

minustempo:

which means the decay rate is 1-0.95 = 5%

minustempo:

12t where t is in years means that 'certain time' is 12 times per year

minustempo:

hope you understand it now!

Grande03:

1-0.95=5 and 12t is incorrect

minustempo:

the decay rate is 5%, the bike's value decreases 12 times per year sorry
