Answer:
The correct option is, Exponential Decay, $23,914.85.
Step-by-step explanation:
A farmer buys a tractor for $50,000.
It is provided that the the tractor depreciates 10% per year.
The exponential function for decay is:
![y=a\cdot (1-r\%)^{t}](https://tex.z-dn.net/?f=y%3Da%5Ccdot%20%281-r%5C%25%29%5E%7Bt%7D)
Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:
![y=a\cdot (1-r\%)^{t}](https://tex.z-dn.net/?f=y%3Da%5Ccdot%20%281-r%5C%25%29%5E%7Bt%7D)
![=50000\times (1-0.10)^{7}\\\\=50000\times 0.4782969\\\\=23914.845\\\\\approx 23914.85](https://tex.z-dn.net/?f=%3D50000%5Ctimes%20%281-0.10%29%5E%7B7%7D%5C%5C%5C%5C%3D50000%5Ctimes%200.4782969%5C%5C%5C%5C%3D23914.845%5C%5C%5C%5C%5Capprox%2023914.85)
Thus, the correct option is, Exponential Decay, $23,914.85.
Tommy’s class rank dropped 10 %
Answer:
y=-4x+9
Step-by-step explanation:
a line parallel to another line means the two lines have the same slope
so you can already cross out the second and last equation
the y-intercept is 9 so it is positive, not a negative 9
