If -3 is one root of the equation 3x2 = – mx – 3 What is the value of m?
What is the other root?

6xy and -16xy000000000

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

There is 240 red cars and there is 400 blue cars because 240/3=80 and 80*5=400
