Aboat costs $11850 and decreases in value by 10% per year how much will the boat be worth after 8 years

the boatf will be worth $5101 after 8 years.

A decrease of 10% is equivalent to multiplying the current value by 0.9.

Every year the value gets multiplied so we get an exponential function in years:

value after y years =

value after 8 years =

The different possible outcomes if you spin a spinner labeled

Red, Blue, Yellow, Green, Purple three times is 360 outcomes

This question has to do with the arrangement since, for each spin, the colors can fall in different positions.

If the spinner is spun once, the total number of possible outcomes if you spin a spinner labeled  Red, Blue, Yellow, Green, Purple is 5! (there are 5 colors)

5! = 5 * 4 * 3 * 2

5! = 120 ways

If you spin the spinner 3 times, the total possible outcomes will be 3(120) = 360 ways
