Step-by-step explanation:
In this problem we are expected to model the depreciated value of the machine after some years of purchase (n years)
initial value of the machine is $225,000
after a year it reduces by 30%
Therefore the new value is now 70% of the initial value
= $157,500
After another year it reduces by 30%
Hence the new value is
= $110250
that after n years the value will be
MN=8
Step-by-step explanation:
since AM/AC = AN/AB = 2/5,
then ∆ABC similar to ∆ANM.
since ∆ABC ~ ∆ANM,
then MN || BC.
by similarity
MN = BC•2/5 = 8
