Tomas has 2 cars. the value today of 1 car is 21000 dollars. the value of this car decreases exponentially by 18% each year. calculate the value of this car after 5 years. give your answer to the nearest hundred dollars

Using the exponential Decay function, the final value of the car after 5 years, with an exponential decrease of 18% will be $7785.54

The exponential deacy function can be represented as :

Substituting the values into the function ::

Y = 21000(1 - 0.18)^5

Y = 21000(0.82)^5

Y = 21000(0.3707398432)

Y = 7785.5367072

Therefore, the final value of the car after 5 years will be $7785.54

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
