Q. A car sells for $5000 \$ 5000 and loses 110 \frac{1}{10} of its value each year.\newlineWrite a function that gives the car's value, V(t),t V(t), t years after it is sold.\newlineV(t)= V(t)= \square
  1. Identify Value and Depreciation Rate: Identify the initial value of the car and the rate at which it depreciates each year.\newlineThe initial value of the car is $5000\$5000. The car loses 110\frac{1}{10} of its value each year, which means it depreciates by 10%10\% annually.
  2. Write Depreciation as Decimal: Write the depreciation as a decimal to use in the function.\newlineSince the car loses 110\frac{1}{10} of its value each year, we convert this fraction to a decimal to get 0.10.1.
  3. Determine Depreciation Factor: Determine the depreciation factor for each year.\newlineTo find the value of the car after each year, we subtract the depreciation rate from 11. This gives us the factor by which the car's value decreases each year.\newlineDepreciation factor = 1depreciation rate=10.1=0.91 - \text{depreciation rate} = 1 - 0.1 = 0.9
  4. Write Function for Car's Value: Write the function for the car's value after tt years.\newlineThe car's value after tt years, V(t)V(t), can be represented by the initial value multiplied by the depreciation factor raised to the power of tt.\newlineV(t)=Initial value×(Depreciation factor)tV(t) = \text{Initial value} \times (\text{Depreciation factor})^t\newlineV(t)=5000×(0.9)tV(t) = 5000 \times (0.9)^t
