Answer:
Correct answer:  Third answer  aₙ = -5 · 2⁽ⁿ ⁻ ¹⁾
Step-by-step explanation:
Given:
-5, -10, -20, -40,.....
First term       a₁ = -5
Second term a₂ = -10
Third term     a₃ = -20
Common ratio or quotient
q = a₂ / a₁ = a₃ / a₂ = -10 / -5 = -20 / -10 = 2
q = 2
First term  a₁ 
Second term a₂ = a₁ · q = a₂ · q²
Third term     a₃ = a₂ · q = a₁ · q³
.....................................................
n-th term aₙ = a₁ · q⁽ⁿ ⁻ ¹⁾
aₙ = -5 · 2⁽ⁿ ⁻ ¹⁾

Well all you need to do is add them so 3.45 + 2.2 = 5.65 then add 0.055 to 5.65 which is 5.705 and last but not least, add 9.03 to 5.705 which is 14.735 which makes 14.735 how many miles she ran. Hope this helps
        
             
        
        
        
The given equation is a wave function. When plotted, the graph is shown in the attached picture. However, the unit is in degrees instead of radians. A unit of π  is equivalent to 180°. This plot could determine one variable if the other is given.
