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:
Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:
Thus, the correct option is, Exponential Decay, $23,914.85.
Answer:48.56
Step-by-step explanation: 121.40-60%=
Answer:
4.63 cubic yard.
Step-by-step explanation:
Given,
The length of sidewalk, l = 100 feet,
Width, w = 5 feet,
Depth, h = 3 inches = 0.25 feet,
Thus, the volume of the concrete needed for making the sidewalk,
= 125 cubic feet,
∵ 1 cubic yard = 27 cubic feet,
⇒ 1 cubic feet = 
cubic yard,
Thus, the quantity of concrete needed = 
≈ 4.63 cubic yard.
