Acar is purchased for
$22,500
. after each year, the resale value decreases by
25%
. what will the resale value be after
5
years?

Not sure if you've learned this but we can use exponents to make an equation.

y = cn^x

with y being the new price, c being the original, n being the rate of increase (or decrease) and x being years. This use of exponents has many names in economics and calculus but i wont bore you with that.

in our case:

we can find n by finding how much will be left of the price.
1.00 - 0.25 = 0.75

f(x) = (22500)(0.75)^x

f(5) = (22500)(0.75)^5
     

       =$5339.35

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
