165 = 0.044v^2 + 1.1v
---
0.044v^2 + 1.1v - 165 = 0
---
the above quadratic equation is in standard form, with a=0.044, b=1.1, and c=-165
---
to solve the above equation using the quadratic formula, plug this:
0.044 1.1 -165
into this: https://sooeet.com/math/quadratic-equation-solver.php
---
the roots (solutions) of the above quadratic equation are:
50
-75
---
in this context, the negative root (-75) doesn&#39;t make sense, so use the positive root (50)
