Determine what type of model best fits the given situation: the value of a vehicle decreased by 20% each year.

Let value intially be = P

Then it is decreased by 20 %.

So 20% of P =

So after 1 year value is decreased by 0.2P

so value after 1 year will be = P - 0.2P (as its decreased so we will subtract 0.2P from original value P) = 0.8P-------------------------------------(1)

Similarly for 2nd year, this value 0.8P will again be decreased by 20 %

so 20% of 0.8P =

So after 2 years value is decreased by (0.2)(0.8P)

so value after 2 years will be = 0.8P - 0.2(0.8P)

taking 0.8P common out we get 0.8P(1-0.2)

= 0.8P(0.8)

-------------------------(2)

Similarly after 3 years, this value will again be decreased by 20 %

so 20% of

So after 3 years value is decreased by

so value after 3 years will be =

taking common out we get

-----------------------(3)

so from (1), (2), (3) we can see the following pattern

value after 1 year is P(0.8) or

value after 2 years is

value after 3 years is

so value after x years will be ( whatever is the year, that is raised to power on 0.8)

So function is best described by exponential model

where y is the value after x years

so thats the final answer

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

answer: it's a
