You have to fill in 3 for x so it woul look like 3x3-3 and that would be 6.
First you find the circumference... 2pi*r... and then you multiply that by 2.125. To find out the total amount of meters that the man walks!
Sorry i just need points, hope you get ur answer
Answer:
8 years
Step-by-step explanation:
Compound interest formula

A(t) is the final amount 55000
A_0= 40000, r= 4% = 0.04, for quarterly n=4

divide both sides by 40000


Take ln on both sides

divide both sides by ln(1.01)

Divide both sides by 4
t=8.00108
So it takes 8 years
Let A(4,12) and B(6,18)
RATE OF CHANGE = m = (y₂ - y₁) / (x₂ - x₁) = (18-12)/ (6-4)
m= 6/2 or m = 3
