Sagot :
The value of this car is decreasing at a rate of 6% per year.
The function V(t) = 38000 (0.94)^t represents the value (in dollars) of a car "t" years after its purchase
What is rate of change?
Rate of change is defined as the change in value with rest to the time is called rate of change.
Here,
V(t) = 38000 (0.94)^t
Cleary, above function is an exponential function
while putting certain values in equation we have certain outcomes.
for,
V(1) = 35720; V(2) =33576.8; V(3) = 31562.192
Now, the rate of change is given by = [V(2)-V(1)/ V(1)] x 100
= [(33576.8-35720)/35720]*100
= 6%
now V(2) x 6% = V(3)
33576.8 x 6% = 31562.192 = V(3)
Thus, The required rate of decreasing care price is 6%.
