the cost for three packages of moving boxes is modeled by the system of equations below. let s represents the cost of each small box, m represents the cost of each medium box, and l represents the cost of each large box. which order triple (s, m, l) represents the cost of the three boxes

Describe the 2 algebraic methods you can use to find the zeros of the function f(t)=-16t^2+400.

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.

Can some one explain this i got sent this. is this a threat i’m scared
