Question

the function y=290000(0.92)^x represents the value of an old home that has been abandoned by its owners x years ago. Find the decay rate of the old home. @Luigi0210

Answer 1

is it 8%

Answer 2

y = 290000(0.92)^x
substitute values of x to find y
if x = 1 , x = 2 , x =3 and so on. I think.

Answer 3

then compare the values of the years

Answer 4

yup its 8%

Answer 5

okay

Answer 6

do you live in united states??

Answer 7

yep

Answer 8

If an exponential decay is written in the form: y = a(1 - r)^x then r will be the rate of decay.
So y = 290000(0.92)^x can be written as y = 290000(1 - 0.08)^x
r = 0.08 or 8%

Answer 9

thanks sir.

Answer 10

you are welcome.
