 Question 233313: The number S of ant species in Kyle Canyon, Nevasa, can be modeled by the function S=-0.000013 + 0.042E - 21 where E is the elevation (in meters). Predict the elevation(s) at which you would expect to find 10 species of ants.Answer by stanbon(57222)   (Show Source): You can put this solution on YOUR website!The number S of ant species in Kyle Canyon, Nevasa, can be modeled by the function S=-0.000013 E^2 + 0.042E - 21 where E is the elevation (in meters). Predict the elevation(s) at which you would expect to find 10 species of ants. --------------------- -0.000013 E^2 + 0.042E - 21 = 10 --------------- -0.000013 E^2 + 0.042E - 31 = 0 --- Solve for E using the quadratic formula and accepting only the positive solution. =========================================== Cheers, Stan H.
