the general equation for depreciation is given by y = a(1 – r)t, where y = current value, a = original cost, r = rate of depreciation, and t = time, in years. a car was purchased 6 years ago for $25,000. if the annual depreciation rate is 11%, which equation can be used to determine the approximate current value of the car?
a. 25,000(0.89)^6 b.(25,000 x 0.11)^6 "answers should look something like this."

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

hope i with whatever it is that you need! : )
