Lyle purchased a motorcycle for $13,430. it depreciates about 4.1% each year. what is the value of the motorcycle after seven years? $13,112.07 $9,575.59 $10,018.58 $17,792.26

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

where  

V is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

substitute the values

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
