Farmer is fed up with aphids and decides to use a pesticide to kill them. unfortunately the
pesticidekills ladybugs at the same rate as aphids. with the pesticide application lotka-volterra
equations are altered to:
dx/dt= 2x−.01xy−.3x
dy/dt=−.5y+.0001xy−.3y
find new equilibrium solutions and advise the farmer if he should go ahead with the pesticide
spraying. explain in a language that a layperson could understand.

7.2 units

Step-by-step explanation:

We have to use the distance formula in this.

The Distance formula says

The distance between two coordinates (a,b) and (c,d) is given by D , then

D= Sqrt { (d-b)^2+(c-a)^ }

Here

(a,b) =  (-2,5)

(c,d) =  ( 4,1)

Hence

D = sqrt { (5-1)^2+ ( 4-(-2))^2}

D = Sqrt { 4^2 + 6^2 }

D= Sqrt { 16+36 }

D = Sqrt 52

D= 7.211

Hence D=7.2 units
