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.
Step-by-step explanation:
(2, -3) is in the 4th quadrant. By the counter clockwise rotation of 90° around the origin, it will be in the 1st quadrant.
Any point in the 1st quadrant has both positive x and y coordinates.
So the answer is (3, 2).
Answer:
62.8 cm
Step-by-step explanation:
The circumference of a circle can be found by
C = 2 * pi *r where r is the radius
C = 2*pi* 10
C = 20 pi
Letting pi be approximated by 3.14
C = 20 *3.14
C =62.8 cm
