The function below models the correlation between the number of hours a plant is kept in sunlight (x) and the height (y), in mm,
to which it grows: y = 2 + 4x
What does the y0intercept of this function represent?
The original height of the plant was 4 mm.
The original height of the plant was 2 mm.
The height of the plant increases by 2 mm for every hour of sunlight it receives.
The height of the plant increases by 4 mm for every hour of sunlight it receives.
Decay equation= P*(1-r)^t P= Principal amount= $30,000 r= rate=0.065 t= time (in years) =5 x=30,000(1-0.065)^5 The value of the car in 5 years is approx. $21,438
