A boat costs 45,000 is depending at a rate of 20% per year. Find the value of the boat after 4 years PLEASE HELP

Year 1 = 36,000

Year 2 = 28,800

Year 3 = 23,040

Year 4 = 18,432

Step-by-step explanation:

Let N = year

Year N = Initial * (1 - rate)^year

Year 1 = 45,000 * (1 - 0.2)^1

Year 1 = 45,000 * (0.8)^1

Year 1 = 45,000 * 0.8

Year 1 = 36,000

Year 2 = 45,000 * (1 - 0.2)^2

Year 2 = 45,000 * (0.8)^2

Year 2 = 45,000 * 0.64

Year 2 = 28,800

Year 3 = 45,000 * (1 - 0.2)^3

Year 3 = 45,000 * (0.8)^3

Year 3 = 45,000 * 0.512

Year 3 = 23,040

Year 4 = 45,000 * (1 - 0.2)^4

Year 4 = 45,000 * (0.8)^4

Year 4 = 45,000 * 0.4096

Year 4 = 18,432

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
