Answer:
Step-by-step explanation:
GIVEN: In , a laptop computer was purchased for . Each year since, the resale value has decreased by . Let be the number of years since .
TO FIND: Let be the value of the laptop computer, in dollars. Write an exponential function showing the relationship between and .
SOLUTION:
value of laptop in
decrease in resale value each year
resale value of laptop after each year
resale value after one year
Now,
Hence relation between value of the laptop computer and time is
Plug in 5 and 10 to the equation.
For the first one would be d(5) = 0.8(5)^2
Multiply the equation d(5) = 4^2
Then you just multiply the exponent the would be d(5) = 10
The second one, you just do the same thing and the answer would be d(10) = 64
No it’s less than because the other ones larger
